Why Informed Consent Fails at Menopause(and how to fix it)

0 Comments

Read Now
 
Summary: How well women feel during menopause depends less on their symptoms and more on their belief that they can manage those symptoms—thus it matters a lot whether doctors help or hurt that belief. Doctors fail women in two ways: using old, outdated information or distrusting good science. Both result in women getting the wrong advice. The fix: women need to build confidence in managing their health and spot good medical care, while doctors need to learn how to tell solid research from weak research. Right now, the system creates a difficult situation, where poor care impairs women's confidence, women’s symptoms get more severe, and leave women with fewer options in life, which makes it harder to design a satisfying life after menopause.Why Informed Consent Fails at Menopause

Quick Takes

#1: The Self-Efficacy MultiplierWomen with high self-efficacy (confidence that they can successfully manage a specific challenge) cope better with menopausal symptoms regardless of severity. But this means that women who struggle the most with self-efficacy will often find themselves seeking help. When they encounter poor medical care, two harms occur: self-efficacy erodes further AND symptoms constrain life more (work, relationships, functioning). Both worsen symptoms. Physicians aren’t just failing to help—they may cause harm by weakening the resource women need most.

#2: Two Paths to Wrong Information
Physicians fail women by: (1) getting stuck on outdated warnings from old hormone formulations, OR (2) rejecting rigorous trials as untrustworthy while focusing on observational studies and animal models as equally valid. Both betray trust. Example: observational studies suggest MHT clearly protects heart and brain, but randomized trials (which remove selection bias) only prove bone benefits. Being "pro-woman" requires engaging with best science, not abandoning rigor.

#3: Informed Consent Needs Both
True informed consent requires scientific accuracy AND respect for autonomy. 
  • Accuracy without respect = paternalism = no informed consent. 
  • Respect without accuracy = informed consent also becomes impossible. 
Women must build self-efficacy and learn to spot quality care. Physicians must develop research literacy, update knowledge regularly, and individualize recommendations. We have work to do.

Favorite Finds

Building Self-Efficacy

There are evidence‑based ways to increase self‑efficacy, including in peri‑ and postmenopausal women. Some interventions have used counseling (Karimlou et al, 2017) or educational sessions (Khandehroo et al, 2025) (Magistro et al, 2025).

Bandura (1977) postulated the existence of 4 sources of self-efficacy, including mastery experiences (choosing a small goal and succeeding), vicarious experiences, verbal persuasion with concrete support, and managing physiological and emotional arousal.


Programs are available in many communities, for example in the Bay Area through
Stanford Medicine and Kaiser Permanente’s virtual Navigating Menopause program, and on the more integrative side, Oakland’s Menopause Wellness Circle, and the Menopausitive Workshop. I am not familiar with the details of these programs but they may be worth exploring.

Science Literacy
Anyone can learn research literacy, for example by taking this beginner “massive open online course” from Coursera: Science Literacy.
Getting what you need from a physician visit (or other provider)
  • What Patients Say, What Doctors Hear – Danielle Ofri’s book gets 4/5 stars on GoodReads.​
  • Doctors Talking with Patients/Patients Talking with Doctors – A classic text on medical communication written mainly for clinicians.
  • SHE+ Patient Advocacy guide — A totally free, very useful toolkit especially addressed to patientswho have experienced dismissal
  • Self‑Advocacy Guide for Women’s Health (Ms.Medicine) – A free (they request your email) women‑specific downloadable guide
  • My Menoplan: menopause‑focused resource that coaches women to set an agenda, prepare a symptom and question list, state visit goals clearly, and use decision tools to guide the discussion
  • Healthline has some good free advice as well.

Deep Dive

The Problem
FACT: Women couldn't vote in the US until 1920 or get credit cards in their own name until 1974. Medical research has systematically neglected women's health. These patterns of dismissing women's importance, autonomy, and concerns persist in clinical practice today.
SOLUTION: Physicians must actively recognize this historical baggage and counteract it with validation, respect, and commitment to filling knowledge gaps.


FACT: Menopause requires of women that they redefine their roles, meaning, relationships, and ways of being in the world. Women who struggle more with this transition experience more disruptive symptoms—and may find themselves needing to seek medical care.
SOLUTION: Recognize menopause as a profound life transition, not just a medical problem. The women in your office are already vulnerable and deserve support.


The Self-Efficacy Connection
FACT: Self-efficacy is your confidence that you can organize and execute a plan to reduce the impact of symptoms on your life. Women with high self-efficacy report better life satisfaction in spite of menopausal symptoms, regardless of symptom severity.
SOLUTION: Build health self-efficacy anytime—even before menopause—the belief that "what I do matters" for health outcomes changes these outcomes.


FACT: When women with lower self-efficacy encounter dismissive or poorly informed physicians, two harms occur: their self-efficacy erodes further AND their symptoms constrain their lives more (work, relationships, sexuality, functioning). Both consequences worsen symptom disruptiveness, creating a downward spiral that can be interrupted by supportive accurate care.
SOLUTION: Physicians must understand they run the risk of worsening one of the root causes of their patients’ distress—they are not just failing to help, but actively damaging women's ability to cope.


The Science Literacy Crisis
FACT: Physicians may fail women in two ways: (1) getting stuck on outdated warnings based on old hormone formulations without knowing current research, OR (2) rejecting rigorous science as untrustworthy while giving undue weight to weaker evidence like observational studies and animal models, or basic petri dish research.
SOLUTION: Real advocacy requires engaging with the best available science. Demand more rigorous research—don't abandon rigor itself. Update knowledge regularly.


FACT: Observational studies show that women who choose hormone therapy (MHT) have better outcomes—but these women also exercise more, eat better, have better healthcare access. This could be the "healthy user effect.” Randomized trials, which remove selection bias, tell a different story: MHT reliably benefits bone health, but cardiovascular and cognitive benefits aren't clearly proven. Also, for breast cancer, while bioidenticals are preferable, if MHT is started within 3 years of menopause and continued past five years, risk increases.
SOLUTION: Understand what research shows so you can be accurate with patients. Promise bone protection, not heart or brain protection. Individualize breast cancer risk assessment. Don't oversell benefits or ignore nuance. Remember to discuss the increased chance of autoimmune disease in women on MHT, and the risks of postmenopausal bleeding. Also be in a position to discuss possible benefits to oral health, skin, hair, and all the other issues MHT can affect.


What Informed Consent Requires
FACT: True informed consent requires both scientific accuracy AND respect for women's autonomy.
SOLUTION: Physicians must weigh multiple factors for each patient: age at menopause, exercise habits, bone health, breast cancer risk, family history, individual goals. Learn to read studies critically, acknowledge uncertainty, and resist oversimplification.


FACT: Most physicians lack training in drawing accurate conclusions from observational studies (selection bias) vs. randomized controlled trials (removes bias), or in clearly defining and evaluating forms of evidence.
SOLUTION: Medical education must include robust research literacy training. Physicians need to understand the consequences of study design.


Action Steps
FOR ALL PATIENTS:
  • Build health self-efficacy anytime
  • Learn what respectful care looks like: listening, validation, evidence-based recommendations
  • Know the red flags: outdated warnings, dismissiveness, inability to explain evidence


FOR PHYSICIANS:
  • Get training in research literacy—understand study design, bias, limitations
  • Examine your biases and update your knowledge regularly
  • Learn to weigh multiple factors for individualized care
  • Apply rigorous evidence evaluation to ALL treatments: hormones, antidepressants, osteoporosis medications


FOR HEALTHCARE SYSTEMS:
  • Stop making overly broad guideline statements
  • Develop better tools for individualized risk assessment
  • Support physician education in research literacy


The Bottom Line
​
FACT: Women deserve physicians who listen AND know how to read studies. They deserve respect AND accuracy. They deserve real empowerment—grounded in the best evidence, honestly interpreted, with uncertainty acknowledged.
SOLUTION: This is informed consent. Anything less is failing women while claiming to help them.

➡️ Multimodal / precision protocols
  • A 9‑month precision‑medicine “multimodal” protocol in patients with MCI or early AD (Toups et al.) reported statistically significant improvements in MoCA, CNS Vital Signs neurocognitive index, and caregiver‑rated change, with MRI volumetrics suggesting reduced hippocampal atrophy; this was a small, uncontrolled proof‑of‑concept study. 
    • Toups K et al. 2022
  • Personalized, multifactorial metabolic programs (diet, hormones, sleep, infection, toxins, etc.) in small uncontrolled series have reported objective cognitive improvements and even return to work in patients with SCI/MCI/early AD.

Kitchen & CookwareCookware
  • 360 Cookware — is highly recommended by my go-to resource Irina Webb
  • Le Creuset — I am in love with mine but it does require some TLC
  • Stargazer Cast Iron — I researched this and it was my favorite, but most cast iron pans will last you forever.
  • All-Clad Pots — Again something that lasts forever and works so well.
  • I am not a fan of any non-stick cookware; after a few years, all the companies so far have ended up in court discussing ingredients they failed to disclose.
Tableware & Storage
  • Glass Cups, Plates, Bowls, and Teapots.
    Unfortunately, too many ceramics leach heavy metals and other toxins, and few companies care to disclose this. I am especially enamored of double-wall borosilicate glass and have an eclectic collection of several that were on sale at Wayfair over the years.
  • Glass and Metal Canisters for the Kitchen
    I live in earthquake prone Bay Area so I keep glass canisters on lower shelves and metal canisters on upper shelves. I’ve found good options at The Container Store.
  • Ball and Mason Jars, Pyrex and SnapLock containers.
    I tend to shop from original websites and prefer to bypass the usual suspects.
Seasonings & Staples
  • Tera's Whey protein powder: tested undetectable for heavy metals (try their website, they may have a discount on there)
  • Diamond Crystal Kosher salt: Unfortunately some salt has a high heavy metal content, and this one tested (by Mamavation) as one of the safer ones.
  • Simply Organics spices and herbs: are tested for heavy metals, which makes them one of the best bets
  • Lundberg rice (especially white rice) is lowest in arsenic
  • 365 brand whole flaxseeds are lowest in heavy metals

  • Grounds for Change Organic Decaf Espresso — I could not find organic decaf espresso in stores anywhere.


Home EssentialsLinens & Textiles
  • Organic Sheets from The California Design Den
  • Organic Towels from Garnet Hill
  • 100% Wool Rugs sometimes from discount sources
Water Filtration
  • Aquagear Water Filter Pitcher; I would be a fan of under-sink water filters, but a system I had previously leaked all over my kitchen sink cabinet and created a very expensive mess that required full mold remediation. I later found out that this is not uncommon for under-sink filters. Also, reverse osmosis filters are good but remove too much magnesium from water, and waste 5x the quantity of water you are drawing.
  • Soda Stream - our favorite way to dilute store-bought kombucha or make lemon fizzy water
  • Air purifiers: there are three brands I trust. Air Doctor for the smallest particles, but also Clean Air Kits for lower priced excellent air filters. Austin Air for VOC filtering as it has a lot more carbon, but doesn’t work as well to filter the smallest particles.
ShoppingBooks from Bookshop: sometimes I want to order a book and not have to drive to my local bookstore — and I don’t want to pile on to the usual suspects websites. I love this option that supports our local bookstores.


Disclaimer: PJ Kabos, Seatopia, and Clean Air Kits are affiliate links. I only recommend products I personally use and love. I am not famous enough (yet!) to be of interest to companies just to promote their products.

Blood Glucose Control Through Gut Health

Blood Glucose Control Through Gut Health

Part 4 of 7: Preventing and Managing Diabetes

Type 2 diabetes doesn't appear overnight. It develops over years as your cells gradually become less responsive to insulin, your pancreas works harder to compensate, and eventually, your blood sugar rises beyond healthy ranges.

What most people don't realize is that your gut bacteria play a direct role in glucose regulation—and optimizing them can produce measurable improvements in fasting blood sugar, HbA1c, and insulin sensitivity, often within 8-12 weeks.

The mechanism isn't mysterious. When bacteria ferment fiber, they produce short-chain fatty acids (SCFAs) that signal your liver to reduce glucose production, improve insulin sensitivity in your muscles and fat cells, strengthen your gut barrier, and reduce the systemic inflammation that worsens insulin resistance.

This is precision medicine through food.

The Clinical Evidence

Study 1: Inulin in Type 2 Diabetes

Type 2 diabetes patients consumed 10g/day of inulin for 8 weeks. Results:

Blood sugar metrics:
- Fasting blood sugar: ↓ 8.5%
- HbA1c: ↓ 10% (e.g., from 7.0% to 6.3%)

Lipid improvements:
- Triglycerides: ↓ 23%
- LDL cholesterol: ↓ 35%

To get 10g inulin from food:
- 1-2 large onions daily, OR
- 65g Jerusalem artichoke, OR
- 20g chicory root, OR
- Multiple smaller portions from garlic, leeks, asparagus throughout the day

Study 2: Oligofructose-Enriched Inulin

An 8-week study using oligofructose-enriched inulin showed:

Glucose control:
- Fasting glucose: ↓ 9.4%
- HbA1c: ↓ 8.4%

Oxidative stress and inflammation:
- Malondialdehyde (MDA): ↓ 39.7%
- Total antioxidant capacity: ↑ 20%
- LDL cholesterol: ↓ 21.7%

The oxidative stress reduction is critical—oxidized LDL is more dangerous than regular LDL because it promotes plaque formation in arteries. Reducing oxidative stress keeps your cholesterol healthier.

Study 3: Lower Dose, Still Effective

A study using just 3g inulin plus fermented soy for 12 weeks showed:
- Improved post-meal glucose response
- Suggested improved muscle insulin sensitivity

This demonstrates that even lower doses work, especially when combined with diverse fiber sources and consistency.

Other Prebiotic Fibers: Inflammation Reduction

Studies using resistant starch, galacto-oligosaccharides, and Jerusalem artichoke showed dramatic reductions in inflammatory markers that drive insulin resistance:

Pro-inflammatory markers decreased:
- C-reactive protein (CRP): ↓ 3.8-4.6 ng/mL
- TNF-α: ↓ 2.9-3.4 pg/mL
- IL-6: ↓ 1.3 pg/mL
- Endotoxin (LPS): ↓ 4.2-6.0 EU/mL

Anti-inflammatory markers increased:
- IL-10: ↑ 1.9 pg/mL
- IL-4: ↑ 7.41 pg/mL

When inflammatory markers drop, insulin sensitivity improves. Your cells become more responsive to insulin's signal, and your pancreas doesn't need to work as hard.

The Mechanism: How Gut Bacteria Control Blood Sugar

Understanding the mechanism helps you appreciate why this works and what you're actually doing when you eat these foods.

Step 1: You Eat Prebiotic Fiber

Sources include:
- Inulin: Onions, garlic, leeks, asparagus, Jerusalem artichoke
- Resistant starch: Beans, lentils, cooked-then-cooled potatoes/rice
- GOS: All legumes (chickpeas, black beans, lentils)
- Various polysaccharides: Vegetables, whole grains, mushrooms

Step 2: Fiber Reaches Your Colon Intact

Because you lack the enzymes to digest these complex carbohydrates, they pass through your small intestine and arrive in your colon where trillions of bacteria are waiting.

Step 3: Bacteria Ferment Fiber into SCFAs

Specific bacterial species—Bifidobacterium, Faecalibacterium prausnitzii, Roseburia, Eubacterium rectale—use their specialized enzymes to break down fiber and produce:
- Butyrate
- Propionate
- Acetate

Step 4: SCFAs Enter Your Bloodstream

These SCFAs are absorbed through your colon wall into the hepatic portal vein and travel throughout your body.

Step 5: Multiple Pathways Improve Glucose Control

Propionate signals your liver:
- Reduces gluconeogenesis (glucose production from non-carbohydrate sources)
- Your liver makes less glucose, so blood sugar stays lower

Butyrate strengthens your gut barrier:
- Prevents bacterial endotoxins from leaking into circulation
- Less endotoxin = less inflammation = better insulin sensitivity

SCFAs reduce systemic inflammation:
- Lower inflammatory cytokines (TNF-α, IL-6, CRP)
- Inflammation interferes with insulin signaling
- Less inflammation = cells respond better to insulin

SCFAs improve insulin sensitivity:
- Direct effects on muscle and fat cells
- Enhance glucose uptake in response to insulin
- Your cells become more responsive to insulin's signal

SCFAs may influence incretin hormones:
- GLP-1 and other gut hormones that regulate glucose
- These hormones stimulate insulin secretion and suppress glucagon
- Better hormonal control of blood sugar

Polyphenols Add Another Layer

Remember from Part 1: 90-95% of polyphenols pass through your small intestine unabsorbed. Bacteria biotransform them into phenolic metabolites that provide additional benefits for blood sugar control.

Polyphenol effects:
- Reduce oxidative stress (preventing LDL oxidation)
- Decrease inflammation in blood vessels
- May improve insulin signaling
- Promote growth of beneficial bacteria (which produce more SCFAs)

Best polyphenol sources for glucose control:
- Berries (especially blueberries)
- Extra virgin olive oil (high-polyphenol versions)
- Green tea
- Dark chocolate (70%+ cacao)
- Coffee
- Apples with skin

Studies show polyphenol consumption increases:
- Bifidobacterium: ↑ 56%
- Lactobacillus: ↑ 220%
- Akkermansia muciniphila (key SCFA producer)

More beneficial bacteria = more SCFA production = better glucose control.

Practical Protocol for Blood Sugar Management

If You Have Pre-Diabetes or Diabetes

Minimum effective dose approach:

Inulin-rich foods (target 8-12g daily):
- 1 large onion (raw in salads or cooked in meals)
- 4-6 cloves garlic (in cooking)
- 1 cup asparagus or leeks
- OR combination of smaller amounts from multiple sources

Resistant starch (target 15-20g daily):
- 1 cup cooked-then-cooled potatoes
- 1 cup beans or lentils
- 1 green/slightly green banana

GOS from legumes:
- 1-2 cups legumes daily (in addition to above)
- Rotate types: black beans, lentils, chickpeas

Polyphenol-rich foods:
- 1 cup berries (fresh or frozen)
- 30-60 mL extra virgin olive oil (2-4 tablespoons)
- 2-3 cups green tea or coffee
- 20-30g dark chocolate (70%+ cacao)

Other beneficial foods:
- Variety of vegetables (especially cruciferous)
- Whole grains (oats, quinoa, brown rice)
- Fatty fish 2-3x weekly (omega-3s improve bacterial composition)

If You're Preventing Diabetes

Lower maintenance approach:

Prebiotic fiber (target 5-8g inulin-type fructans):
- Onions and garlic in daily cooking
- Regular inclusion of asparagus, leeks, or artichokes
- Diverse vegetable intake

Resistant starch (target 10-15g):
- Beans/lentils 4-5x weekly
- Occasional cooked-then-cooled potatoes or rice
- Regular oats

Polyphenols:
- Daily berries (0.5-1 cup)
- 30 mL EVOO minimum (2 tablespoons)
- Green tea or coffee
- Dark chocolate a few times weekly

Overall diversity:
- Aim for 30+ different plant foods weekly
- Include variety of vegetables, fruits, legumes, whole grains, nuts, seeds
- Consistency matters more than perfection

Timeline: What to Expect

Weeks 1-2:
- May experience increased gas/bloating as bacteria adjust
- This is normal and typically resolves
- Increase fiber gradually if this is problematic

Weeks 2-4:
- Digestive symptoms improve
- Better satiety after meals
- More stable energy throughout day
- Fewer cravings for refined carbohydrates

Weeks 4-8:
- Noticeable improvements in fasting blood sugar (if monitoring at home)
- Better post-meal glucose response
- Weight may decrease modestly (if overweight)

Weeks 8-12:
- Measurable improvements in HbA1c
- Lipid panel improvements (lower triglycerides, LDL; higher HDL)
- Reduced inflammatory markers (if tested)
- Potential reduction in diabetes medication needs (work with your doctor)

Beyond 12 weeks:
- Continued optimization as bacterial populations stabilize
- Long-term protection against complications
- Sustained improvements with consistent approach

Important Considerations

Individual Variation

Not everyone produces the same amount of SCFAs from identical fiber intake. Factors include:

Current bacterial composition:
- Previous antibiotic use may have depleted key species
- Years of low-fiber diet starve SCFA producers
- Some people lack specific beneficial species

Baseline inflammation:
- Higher baseline inflammation may show more dramatic improvements
- Lower baseline may show more modest (but still meaningful) changes

Medication effects:
- Metformin actually supports beneficial bacteria
- Some medications may interfere with bacterial function
- Don't stop medications without medical guidance

Working with Medication

As your blood sugar improves, you may need medication adjustments. Signs you need to discuss with your doctor:
- Fasting blood sugar consistently lower than usual
- Hypoglycemic episodes
- Post-meal readings significantly improved
- HbA1c dropping below target range

Never adjust diabetes medications on your own. Work closely with your healthcare provider to titrate doses as your glucose control improves.

Monitoring Your Progress

Home monitoring:
- Fasting blood sugar daily (first thing in the morning)
- Post-meal readings 1-2 hours after main meals
- Track trends over weeks, not day-to-day fluctuations

Lab testing (every 3-6 months):
- HbA1c (comprehensive 3-month average)
- Fasting glucose
- Lipid panel
- Consider inflammatory markers (CRP, if available)

Keep a food journal:
- Track which fiber sources you're eating
- Note amounts and frequency
- Correlate with blood sugar readings
- Identify what works best for you

Beyond Blood Sugar: Additional Benefits

When you optimize gut bacteria for glucose control, you simultaneously improve:

Cardiovascular health:
- Lower LDL and triglycerides
- Reduced oxidative stress
- Less arterial inflammation
- Better blood pressure (in many studies)

Weight management:
- SCFAs increase satiety
- Better glucose control reduces cravings
- Improved metabolism
- Modest weight loss common (especially with excess weight)

Cognitive function:
- Reduced brain inflammation
- Better blood-brain barrier function
- Neuroprotective metabolites from polyphenols
- (We'll cover this more in Part 6)

Overall inflammation:
- System-wide reduction in inflammatory markers
- Better immune function
- Reduced risk of inflammatory complications

Common Mistakes

1. Inconsistency
Eating high-fiber meals sporadically doesn't establish stable bacterial populations. Your bacteria need regular feeding to thrive and produce consistent SCFA levels.

2. Too much too fast
Jumping from 10g to 40g fiber overnight causes digestive distress. Increase gradually over 2-4 weeks. Your bacteria need time to expand populations.

3. Only focusing on one fiber type
Eating only beans or only inulin limits bacterial diversity. Different fibers feed different species. You need variety.

4. Ignoring food preparation
The cooling trick for resistant starch matters. Overcooking destroys some beneficial compounds. These details affect results.

5. Expecting immediate results
Blood sugar improvements take weeks, not days. HbA1c reflects 3-month averages. Be patient and consistent.

How We Help

In our practice, we create personalized protocols based on:

Your current status:
- Current HbA1c and fasting glucose
- Medication regimen
- Dietary starting point
- Digestive tolerance

Your specific situation:
- Food preferences and restrictions
- Cooking skills and time
- Budget considerations
- Cultural food preferences

Structured approach:
1. Assess baseline (labs, diet history, symptoms)
2. Create gradual introduction plan
3. Monitor progress with home testing and labs
4. Adjust fiber types and amounts based on response
5. Coordinate with your physician on medication adjustments
6. Optimize for long-term sustainability

The clinical evidence shows what's possible. Our role is helping you achieve those results in your actual life, with your specific circumstances.

Part 3 of 7: Practical Food Strategies

In Parts 1 and 2, you learned that you can't digest fiber or polyphenols without gut bacteria, and that when bacteria ferment these compounds, they produce SCFAs that regulate your metabolism, inflammation, and brain health.

Now comes the practical question: What do you actually eat?

This isn't about generic advice to "eat more vegetables." Different fibers feed different bacterial populations, and different bacteria produce different beneficial compounds. Your goal is diversity and consistency—feeding a wide range of bacterial species with the right substrates.

The Four Main Categories of Prebiotic Fiber

1. Inulin-Type Fructans

These are prebiotics that pass through your small intestine intact and reach your colon where specific bacteria ferment them into SCFAs.

Best food sources:
- Onions (2.5-6g inulin per 100g) - Raw has more than cooked
- Garlic (9-16g per 100g) - One of the richest sources
- Leeks (3-10g per 100g)
- Asparagus (2-3g per 100g)
- Jerusalem artichoke (16-20g per 100g) - Highest source, but can cause gas
- Chicory root (15-20g per 100g) - Often sold as a supplement
- Slightly green bananas (resistant starch + inulin)

Clinical dosing: Studies showing blood sugar improvements used 10g/day of inulin. To get this from food:
- 1-2 large onions (raw or cooked), OR
- 65g Jerusalem artichoke, OR
- 20g chicory root, OR
- Multiple smaller portions from various sources (recommended approach)

Which bacteria these feed: Bifidobacterium, Lactobacillus, Faecalibacterium prausnitzii - all major SCFA producers

2. Resistant Starch

This is starch that "resists" digestion in your small intestine and reaches your colon intact. There are different types, but the most practical for daily eating is RS3 (retrograded starch).

Best food sources:
- Cooked-then-cooled potatoes - Cooling after cooking increases resistant starch 2-3x
- Cooked-then-cooled rice - Same principle applies
- Cooked-then-cooled pasta
- Beans and lentils (15-20g RS per 100g cooked)
- Green/slightly green bananas (8-12g RS per 100g)
- Oats (especially overnight oats)

The cooling trick: When you cook and then cool starches (refrigerate overnight), the starch molecules rearrange into a form your enzymes can't break down. You can reheat them and they'll retain much of the resistant starch.

Clinical dosing: Studies used 15-30g/day of resistant starch. To get 20g:
- 1 cup cooked-then-cooled potatoes + 1 cup beans, OR
- 2 cups cooked-then-cooled rice, OR
- Mix of beans, lentils, and cooled starches throughout the day

Which bacteria these feed: Ruminococcus bromii, Bifidobacterium, Eubacterium rectale - butyrate producers

3. Galacto-Oligosaccharides (GOS)

These are present in all legumes and are particularly effective prebiotics.

Best food sources:
- Lentils (all varieties - red, green, brown, black)
- Chickpeas/garbanzo beans
- Black beans
- Kidney beans
- Pinto beans
- White beans/cannellini
- Peas (green peas, split peas)

Practical target: 1-2 cups of legumes daily provides substantial GOS plus resistant starch, fiber, and protein

Which bacteria these feed: Bifidobacterium (significantly increased), Lactobacillus, various butyrate-producing species

4. Non-Starch Polysaccharides

These are complex carbohydrates from various plant sources.

Best food sources:
- Mushrooms (all varieties - button, shiitake, oyster, portobello) - contain beta-glucans
- Root vegetables: Carrots, beets, sweet potatoes, parsnips, turnips
- Whole grains: Oats, barley, wheat berries, quinoa, brown rice
- Cruciferous vegetables: Broccoli, cauliflower, Brussels sprouts, cabbage

Practical target: Include 2-3 different types daily

Which bacteria these feed: Diverse populations depending on the specific polysaccharide structure

Polyphenol-Rich Foods: Dual Benefits

Remember from Part 1: 90-95% of polyphenols pass through your small intestine unabsorbed. Bacteria biotransform them into absorbable metabolites AND polyphenols promote beneficial bacterial growth.

Top Polyphenol Sources

Berries (especially important):
- Wild blueberries - Higher polyphenol content than cultivated
- Strawberries
- Black raspberries
- Blackberries
- Cranberries

Clinical dosing: Studies showing cognitive benefits used 178g wild blueberries daily (about 1.5 cups). Start with 0.5-1 cup daily of mixed berries.

Extra Virgin Olive Oil (EVOO):
- High-polyphenol versions (800+ mg/kg polyphenol content)
- Look for darker color, peppery/bitter taste
- Brands: Check labels or sites like Olive Oil Lovers, PJ Kabos, Lakonikos Zoi

Clinical dosing: 30-60 mL (2-4 tablespoons) daily showed benefits for cardiovascular health and cognition. Use in salad dressings, drizzle on cooked vegetables, or take straight.

Other rich sources:
- Green tea (3-4 cups daily, or matcha)
- Coffee (2-3 cups daily)
- Dark chocolate (70%+ cacao, 20-30g daily)
- Pomegranate (fresh fruit or 100% juice)
- Apples with skin
- Walnuts (1-2 oz daily)

Effect on bacteria: Increases Bifidobacterium (56%), Lactobacillus (220%), Akkermansia muciniphila, while decreasing harmful Clostridium species.

Other Beneficial Compounds

Sulforaphane Sources

  • Broccoli sprouts (highest concentration - 10-100x mature broccoli)
  • Broccoli (especially lightly steamed)
  • Brussels sprouts
  • Cauliflower
  • Cabbage
  • Kale

Tips: Chop and wait 40 minutes before cooking to allow enzyme activation. Lightly steam rather than boil. Add mustard powder to increase sulforaphane availability.

Carotenoid Sources

  • Orange/yellow vegetables: Carrots, sweet potatoes, butternut squash, pumpkin
  • Dark leafy greens: Spinach, kale, collards (contain lutein and zeaxanthin)
  • Red/orange fruits: Tomatoes, red peppers, watermelon
  • Salmon and fatty fish (astaxanthin)

Effect on bacteria: Shifts microbiome toward Akkermansia, Lachnospiraceae, Alistipes (beneficial species) and away from pro-inflammatory taxa.

Omega-3 Sources

  • Cold water fish: Salmon, sardines, mackerel, anchovies (2-3 servings weekly)
  • Flaxseed (ground, 1-2 tablespoons daily)
  • Chia seeds (1-2 tablespoons daily)
  • Walnuts (1-2 oz daily)

Effect on bacteria: Alters composition toward anti-inflammatory taxa and improves metabolic signaling.

The 30-Plant Challenge: Why Variety Matters

Research shows that people who eat 30+ different plant foods per week have more diverse gut bacteria than those eating 10 or fewer.

Why diversity matters:
- Different fibers have different structures (degree of polymerization, particle size, solubility, viscosity)
- Different bacteria specialize in different fiber types
- Cross-feeding: One bacterium's breakdown products become another's fuel
- More diverse bacteria = more comprehensive health benefits

What counts toward 30:
- All vegetables
- All fruits
- All legumes (beans, lentils, peas)
- All whole grains
- All nuts and seeds
- Herbs and spices (yes, these count!)

Practical example week:

Vegetables (10): Onions, garlic, broccoli, carrots, spinach, tomatoes, bell peppers, mushrooms, asparagus, Brussels sprouts

Fruits (7): Blueberries, strawberries, apples, bananas, avocado, pomegranate, oranges

Legumes (4): Black beans, lentils, chickpeas, peas

Whole grains (4): Oats, brown rice, quinoa, whole wheat

Nuts/seeds (3): Walnuts, chia seeds, flaxseed

Herbs/spices (2+): Turmeric, ginger, cinnamon, black pepper, oregano

Total: 30+

Practical Daily Eating Strategy

Morning:
- Overnight oats with chia seeds, ground flaxseed, berries, walnuts
- Green tea or coffee

Lunch:
- Large salad with mixed greens, carrots, tomatoes, chickpeas, avocado
- EVOO-based dressing with garlic
- Side of cooked-then-cooled potato salad or rice

Snack:
- Apple with skin
- Dark chocolate (70%+ cacao)
- OR green banana
- OR small serving of nuts

Dinner:
- Salmon or other protein
- Roasted vegetables (broccoli, Brussels sprouts, sweet potato)
- Lentils or beans
- Side salad with EVOO

Throughout day:
- 30-60 mL extra virgin olive oil (in dressings, drizzled on food)
- 3-4 cups green tea or 2-3 cups coffee
- Plenty of water

Common Mistakes to Avoid

1. Too much too fast
If you're currently eating low fiber, jumping to 40g+ fiber overnight will cause gas, bloating, and discomfort. Your bacteria need time to adjust. Increase gradually over 2-4 weeks.

2. Only eating one type of fiber
Eating only beans or only inulin feeds limited bacterial species. You need variety to support diverse populations.

3. Inconsistency
Eating high fiber 2 days per week doesn't work. Your bacterial populations adapt to regular feeding patterns. Consistency matters more than occasional "perfect" days.

4. Ignoring food preparation
The cooling trick for resistant starch actually matters. Overcooking vegetables destroys sulforaphane. These details affect what your bacteria receive.

5. Buying low-polyphenol olive oil
Not all EVOO is equal. Low-polyphenol versions (most commercial brands) don't provide the same benefits. Check labels or buy from specialty sources.

What About Supplements?

Studies used concentrated forms (inulin powder, berry extracts) for precision and compliance. But whole foods provide:
- Multiple types of fiber in one food
- Phytonutrients beyond what's studied
- Synergistic effects from food matrix
- Better adherence (real food vs powder)

Our approach: Prioritize whole foods. Consider targeted supplementation temporarily if:
- You are accustomed to it and are making a transition
- You're traveling or in situations where food access is limited

Monitoring Your Progress

How do you know it's working?

Subjective markers (2-4 weeks):
- Improved digestion and regularity
- Better energy levels
- Reduced bloating (after initial adjustment period)
- Better satiety after meals

Objective markers (8-12 weeks):
- Fasting blood sugar and HbA1c
- Lipid panel (total cholesterol, LDL, HDL, triglycerides)
- Inflammatory markers (CRP, if tested)
- Blood pressure
- Cognitive function (if that's a concern)

Advanced testing (optional):
- Stool microbiome analysis
- SCFA production levels
- Gut barrier function markers

How We Help

In our practice, we don't hand you this list and say "good luck." We:

  1. Assess your current diet - What are you already eating? Where are the gaps?
  2. Identify your tolerance - How much fiber can you handle now? What's the realistic starting point?
  3. Create a personalized plan - Based on your health goals, food preferences, and lifestyle
  4. Provide specific meal plans - Not just food lists, but actual meals and recipes
  5. Monitor and adjust - Track your progress with objective markers and refine the approach
  6. Address barriers - Time constraints, cooking skills, food access, budget concerns

The clinical evidence is clear: the right foods, eaten consistently, in the right combinations, produce measurable health improvements. But translating research into daily practice requires personalization.

What Are SCFAs and How Do They Control Your Metabolism

0 Comments

Read Now
 

Part 2 of 7: Understanding Short-Chain Fatty Acids

When your gut bacteria ferment dietary fiber, they produce three main molecules: butyrate, propionate, and acetate. These are short-chain fatty acids (SCFAs), and they're not waste products—they're powerful signaling molecules that regulate your metabolism, immune function, and inflammation throughout your entire body.

Here's what makes them remarkable: after production in your colon, SCFAs are absorbed into your bloodstream and travel to your liver, brain, pancreas, muscles, fat tissue, and bones. They bind to specific receptors on cells in these organs and trigger cascades of beneficial effects.

What happens in your gut doesn't stay in your gut.

The Three Main SCFAs and What They Do

Butyrate: Your Gut's Preferred Fuel

Butyrate is the primary fuel source for colonocytes (the cells lining your colon). About 70% of the energy these cells use comes from butyrate produced by bacteria.

What it does:
- Strengthens the intestinal barrier, preventing "leaky gut" where bacterial toxins (endotoxins) enter your bloodstream
- Provides anti-inflammatory signaling throughout your body
- Regulates immune cell function
- May protect against colon cancer by promoting healthy cell turnover

When your gut barrier weakens, bacterial endotoxins leak into circulation. This triggers systemic inflammation that worsens insulin resistance, contributes to cardiovascular disease, and accelerates cognitive decline. Butyrate prevents this cascade.

Which bacteria produce it: Faecalibacterium prausnitzii, Roseburia, Eubacterium rectale, Anaerostipes

What feeds them: Resistant starch (beans, lentils, cooked-then-cooled potatoes/rice), inulin (onions, garlic, asparagus), and various fibers from whole grains

Propionate: The Glucose Regulator

Propionate travels to your liver where it directly influences glucose metabolism and lipid production.

What it does:
- Signals your liver to reduce glucose production (gluconeogenesis)
- Increases feelings of fullness (satiety) by triggering gut hormones like PYY and GLP-1
- May improve insulin sensitivity
- Influences cholesterol synthesis

This is why fiber intake improves blood sugar control even in people without diabetes—propionate is literally telling your liver to produce less glucose.

Which bacteria produce it: Bacteroides, Phascolarctobacterium, Dialister, Veillonella, Megasphaera

What feeds them: Inulin-type fructans, resistant starch, and various complex carbohydrates

Acetate: The Systemic Messenger

Acetate is the most abundant SCFA in your colon and enters systemic circulation at higher levels than butyrate or propionate.

What it does:
- Influences metabolism throughout the body
- Modulates immune function in distant organs
- May affect appetite regulation through central nervous system pathways
- Serves as a substrate for cholesterol and fatty acid synthesis
- Crosses the blood-brain barrier and may influence brain function

Which bacteria produce it: Many bacterial species produce acetate, making it the most abundant SCFA

What feeds them: Wide variety of dietary fibers and fermentable carbohydrates

How SCFAs Actually Improve Your Health

Blood Sugar Control

The mechanism is elegant and well-documented:

  1. You eat fiber (inulin, resistant starch, diverse plant foods)
  2. Bacteria ferment it and produce propionate and butyrate
  3. Propionate signals your liver to reduce glucose production
  4. Butyrate strengthens your gut barrier, reducing inflammatory endotoxin leakage
  5. Less systemic inflammation = better insulin sensitivity

The clinical evidence: In Type 2 diabetes patients, 10g/day of inulin for 8 weeks:
- Fasting blood sugar ↓ 8.5%
- HbA1c ↓ 10%
- Triglycerides ↓ 23%
- LDL cholesterol ↓ 35%

Another study using oligofructose-enriched inulin showed similar results plus a 39.7% decrease in oxidative stress markers.

Inflammation Reduction

Studies using resistant starch, galacto-oligosaccharides, and Jerusalem artichoke (all SCFA-producing fibers) showed:

Pro-inflammatory markers decreased:
- C-reactive protein (CRP): ↓ 3.8-4.6 ng/mL
- TNF-α: ↓ 2.9-3.4 pg/mL
- IL-6: ↓ 1.3 pg/mL
- Endotoxin (LPS): ↓ 4.2-6.0 EU/mL

Anti-inflammatory markers increased:
- IL-10: ↑ 1.9 pg/mL
- IL-4: ↑ 7.41 pg/mL

This shift from inflammatory to anti-inflammatory signaling demonstrates how feeding your gut bacteria the right substrates fundamentally changes your body's inflammatory state.

In rheumatoid arthritis patients, 10g/day of inulin for 8 weeks produced:
- Decreased C-reactive protein
- Lower disease activity scores
- Increased hand grip strength
- Decreased morning stiffness

Cardiovascular Protection

SCFAs influence cardiovascular health through multiple mechanisms:

  1. Reduced systemic inflammation (less inflammatory damage to blood vessels)
  2. Improved lipid profiles (propionate influences cholesterol synthesis)
  3. Better blood pressure regulation (SCFAs activate receptors that influence vascular tone)
  4. Reduced oxidative stress (less LDL oxidation)

The gut-liver axis is critical here. What your bacteria produce in your colon directly influences what your liver produces—including cholesterol, glucose, and inflammatory mediators.

Why SCFA Production Varies Between People

Not everyone produces the same amount of SCFAs, even when eating identical foods. This depends on:

Bacterial composition: Do you have sufficient populations of SCFA-producing bacteria?
- Previous antibiotic use can deplete key species
- Low-fiber diets starve SCFA producers
- Chronic stress alters bacterial populations

Fiber diversity: Different bacteria specialize in different fibers
- Eating only one type of fiber feeds limited bacterial species
- Diverse fiber intake supports diverse bacterial populations
- Target: 30 different plant foods per week

Colonic transit time:
- Too fast: bacteria don't have enough time to ferment fiber
- Too slow: may produce excess gas and discomfort
- Individual variation is significant

The Cross-Feeding Effect

Here's where it gets interesting: bacteria don't work in isolation. They cooperate through a process called "cross-feeding."

Primary degraders break down complex fibers into smaller pieces. Secondary degraders then use these breakdown products as their fuel. One bacterium's waste is another's food.

This assembly line increases overall SCFA production efficiency. But it only works when you have diverse bacterial populations—which requires diverse fiber intake.

This is why eating varied fiber sources matters more than just "eating more fiber."

Practical Takeaways

To maximize SCFA production:

  1. Eat diverse fiber sources daily
  2. Resistant starch: beans, lentils, cooked-then-cooled potatoes/rice
  3. Inulin: onions, garlic, leeks, asparagus, slightly green bananas
  4. Various fibers: whole grains, vegetables, fruits

  5. Aim for 30 different plant foods per week

  6. Include herbs and spices—they count
  7. Variety feeds diverse bacterial populations
  8. Different bacteria produce different SCFAs

  9. Be consistent

  10. Bacterial populations adapt to regular feeding
  11. Sporadic fiber intake doesn't allow stable communities to establish
  12. Think of it as feeding a garden, not just yourself

Why You Can't Digest Healthy Foods Without Gut Bacteria

0 Comments

Read Now
 
​
Part 1 of 7: Understanding the Gut-Health Partnership
Here's something that might surprise you: 90-95% of the polyphenols you consume from blueberries, olive oil, tea, and dark chocolate pass through your small intestine completely unabsorbed.
Your body can't process them. The molecular structures are too complex, and you lack the enzymes needed to break them down.

But in your colon, gut bacteria transform these compounds into simple metabolites that ARE absorbable—and that actually benefit your health. Without this bacterial work, those expensive "superfoods" you're buying deliver almost no benefit.

This is the first in our 7-part series where we'll explain exactly how this gut-bacteria partnership works and how optimizing it leads to measurable improvements in blood sugar, cardiovascular health, cognitive function, and inflammation.

The Two-Part Digestion System You Didn't Know You Had
Part 1 (Your Small Intestine): You digest the basics—simple sugars, amino acids, fats, vitamins, minerals.
Part 2 (Your Colon): Bacteria digest what you can't—dietary fiber and complex polyphenols.
You literally lack the carbohydrate-active enzymes (CAZymes) needed to break down fiber. Your gut bacteria evolved to specialize in this task. They possess the enzymatic machinery you're missing, and in return for being fed, they produce molecules that regulate your metabolism, immune system, and brain health.

What Your Bacteria Actually Do
When you have enough of them, your gut bacteria perform three critical functions:
1. Transform Fiber Into SCFAs (Short-Chain Fatty Acids)
When bacteria ferment fiber, they produce butyrate, propionate, and acetate.
These aren't waste products—they're signaling molecules that:
  • Tell your liver to reduce glucose production
  • Improve insulin sensitivity in muscles and fat cells
  • Strengthen your gut barrier
  • Travel through your bloodstream to your brain, lungs, pancreas, and other organs

In diabetes patients, 10g/day of inulin (a prebiotic fiber) for 8 weeks dropped fasting blood sugar by 8.5%, HbA1c by 10%, and LDL cholesterol by 35%. The mechanism? Fiber feeds bacteria → bacteria produce SCFAs → SCFAs regulate glucose metabolism.

2. Convert Polyphenols Into Absorbable Metabolites
Those polyphenols from berries and olive oil that you can't absorb? Bacteria break them down into phenolic metabolites that:
  • Reduce oxidative stress (keeping cholesterol healthier)
  • Decrease inflammation in blood vessels and brain
  • Cross the blood-brain barrier for neuroprotection
  • Support BDNF production (critical for memory and learning)

Studies show 30 mL/day of high-polyphenol olive oil for 6 months improved memory, behavior, and blood-brain barrier function in people with mild cognitive impairment.

3. Shift Your Bacterial Population Toward Health
The right foods don't just feed bacteria—they change which species dominate. Polyphenol consumption increases:
  • Bifidobacterium (up 56%)
  • Lactobacillus (up 220%)
  • Akkermansia muciniphila (key SCFA producer)
While decreasing harmful species linked to inflammation and GI disease.

Why Some People Don't Get Results
Many patients come to us after years of "clean eating" but still struggling with blood sugar, inflammation, or cognitive decline. The problem? Their gut bacteria were disrupted by:
  • Restrictive diets that eliminated diverse plant foods
  • Antibiotic courses
  • Chronic stress
  • Standard American diets low in fiber and polyphenols
  • Toxins in the environment
  • Lack of fermented foods
Even if you're eating organic blueberries and expensive olive oil, without optimized gut bacteria, you're not getting the metabolic, cardiovascular, and cognitive benefits you're paying for.

Time-Restricted Eating and the Gut Microbiome: Health Implications

1 Comment

Read Now
 

Time-restricted eating (TRE) is a highly promising dietary approach that improves health outcomes in part by modifying the gut microbiome. Recent research is revealing how the timing of meals affects our microbial communities and, in turn, our health (Pérez-Gerdel et al., 2023).

Impact on Microbial Composition
Studies show that TRE can significantly change gut microbial ecology, though these changes return to baseline when the intervention stops (Pérez-Gerdel et al., 2023) suggesting that TRE is a lifestyle and not a one-time intervention. Research has documented several key changes in bacterial populations, and these appear particularly important for metabolic health and obesity resistance (Zeb et al., 2023; Ribas-Latre et al., 2024).

Some details:
    - Increased Bacteroidetes and Prevotellaceae
    - Decreased Escherichia, Shigella, and Peptostreptococcus
    - Enhanced cyclical variety in metabolically important bacterial families
    - Reintroduction of beneficial Ruminococcaceae, including Oscillibacter species
    - Increased Lachnospiraceae, Parasutterella, and Romboutsia with 12-week TRE
    - Enrichment of Parabacteroides distasonis and Bacteroides thetaiotaomicron in shorter interventions like Ramadan fasting

How TRE Works
Time-restricted eating improves metabolic markers through the production of beneficial compounds, regulation of daily rhythms, control of metabolism, and effects on immune function (Ribas-Latre et al., 2024).

Bile Acid Signaling
TRE works partly by changing bile acid signaling, which is involved in most aspects of health, from glucose regulation to liver function, and immune competence. Lactobacillus bacteria, which increase with TRE, produce enzymes that modify bile acids, affecting both metabolism and heart health (Zeb et al., 2023).

Metabolic Control
TRE influences metabolism through several mechanisms:
   - Early-day eating reduces insulin levels throughout the day (Longo & Panda, 2016) which would be expected to reduce diabetes risk;
   - Changed bacterial populations affect brain signaling through glucocorticoid pathways (Luo et al., 2018);
   - Microbiome changes alter metabolic signaling molecules (Sonnenburg & Bäckhed, 2016), which alters how diet impacts glucose and lipid regulation.

Health Benefits
Cardiovascular Health: Recent studies show clear links between TRE-induced microbiome changes and improved heart health markers (Zheng et al., 2024).

General Health: Research shows promising effects from research in mice. TRE can:
   - Increase protective bile acids like TUDCA
   - Improve gut barrier function Increase protective goblet cells in the gut
   - Reduce inflammatory cytokines in the blood

Eye Health: In mice, these changes brought about by TRE protect against diabetic eye disease (Beli et al., 2018) and may reverse age-related eye changes (Huston et al., 2024)

Stroke Protection: Changes in the microbiome caused by TRE can reduce stroke damage in animal studies (Delgado Jimenez et al., 2021).

Clinical Considerations (in humans): Several key factors affect TRE's success:

   - Duration: Brief interventions (8-hour fasting) may not sufficiently change the microbiome in people with obesity (Guo et al., 2021).
   - Individual Differences: Response to TRE varies significantly between people.
   - Timing: Early-day eating appears most effective for metabolic benefits (Ribas-Latre et al., 2024).

Conclusion
Evidence strongly supports TRE's ability to beneficially modify the gut microbiome and improve health markers. The only thing holding me back from enthusiastically recommending that everyone adopt a TRE lifestyle is that some studies have shown loss of muscle mass. This was seen for instance in a study of individuals fasting 16 hours per day, and eating between 12 noon and 8 PM. Thus the TRE for them was both short and late in the day (Lowe et. al, 2020).

I have a tip: if you have chosen to eat within a short window (because you are trying to keep calories down) a bit too late in the day, make sure you engage in resistance training. You can gain muscle mass on TRE when you are engaged in strength training. In a 2021 study (Kotarsky), TRE subjects lost more weight than control subjects. TRE subjects gained 0.5% muscle, while control subjects gained 1.9%. The difference was not statistically significant, and neither group lost muscle mass.

In another study, young men assigned to TRE (and strength training) made improvements in muscle strength (though not muscle size) that were sometimes superior to that of the subjects who were eating normally (Tinsley).
​

So we can improve on Michael Pollan’s excellent health advice “Eat food. Not too much. Mostly plants.” And “stop early in the day.” But watch your muscle mass because all the research is not in.

WHAT YOUR BACTERIA WANT YOU TO KNOW

0 Comments

It's been 34 years since I graduated from medical school, so I’ve seen quite a few ideas come and go. In my opinion, the two most exciting advances in our understanding have been the discovery of the microbiome and of epigenetics.

We now know that bodies change on a daily or even hourly basis via processes that are potentially reversible: the modification of gene expression (epigenetics), and the modification of a factory of organisms living within us. This collection of microscopic organisms is called “microbiota.” The collection of all their genetic material is the “microbiome.” Estimates are that 30-50% of the substances circulating in our bloodstream are made by bacteria.


HOW DISEASE DEVELOPS

These minute-to-minute changes in our gene expression and microbiota, if they keep going in the same direction over time, result in the symptoms of a variety of conditions. To the extent these changes are reversible, the array of symptoms they result in, which we call “diseases,” are also reversible, unless much damage has been done.

This may be easier to understand for anyone who has tried to tend a garden: the same plant in two different spots, say one with direct sun, and one in the shade, will look entirely different. If you notice this within a few weeks of putting your plant in the ground, you can move the plant and save it. If you wait too long, the plant may not survive. It’s easy to see in plants because they have “continuous embryogenesis,” that is, they never stop developing. It’s harder to see in humans because we look fairly unchanged from the outside. But on the inside, our immune system and endocrine system set the tone best suited to the moment.

What tells our immune system what the tone should be? It’s done by turning certain genes on , and other genes off. This is also known as modification of gene expression (our genes as well as microbial genes). The signals come from our changing gut bacteria, the food we eat, the activities we engage in, how much sleep we get, the events that occur in our lives and how we interpret them in light of everything that has come before, and the impact of toxins from the environment. Each of these affects all other aspects, and each impacts gut bacteria, which as I just remarked, make 30-50% of the substances in our blood: these substances get to work changing the immune and metabolic characteristics in ways we are barely beginning to understand.

Thus the task is to get to the root cause of a problem in order to reverse this problem. We target diet, exercise, sleep, stress, events, and toxins, and in turn that modifies our gut bacteria. Much of conventional medicine uses medications meant to modify our own biochemistry, and that has proven quite useful, but too often does not restore us back to a state of health.

HOW TO IMPROVE GUT BACTERIA

So the question is how to impact our microbiota, given that they have such broad impacts. Clearly, diet, stress reduction, exercise, sleep, and toxin exposure will play a role. A recent article by leading gut researchers at Stanford (see article by Wastyk et. al. below), including Erika and Justin Sonnenburg, describes a 10 week intervention where subjects were instructed to either double the amount of fiber in their diet, or drastically increase their intake of fermented foods. The researchers thought that if they could modify the microbiota, they might find improvements in the immune system and metabolic markers (glucose regulation for example, or blood pressure and cholesterol).


To their surprise, adding fermented foods worked much better overall than increasing fiber. Their conclusions were that too many people don’t have a good enough microbiome (the bacteria in their gut between them do not have enough genes) to make proper use of the added fiber. A few people in the study were indeed able to make use of the fiber (as evidenced by whether there were undigested carbohydrates in their stool, or not) and those people got an anti-inflammatory boost from the fiber.

However, in the fermented food section of the study, 10 weeks was sufficient to improve microbiota diversity. The new bacteria acquired were not mostly from the fermented foods themselves. They were from elsewhere in the environment, but the fermented foods were somehow able to help them thrive. The subjects in the study consumed about 6-7 portions of fermented foods each day. One portion is equivalent to 6 oz of kefir, yogurt, fermented cottage cheese, 1/4 cup of kimchi or sauerkraut, or 2 oz of fermented brined vegetable juice.

In a side experiment (see video referenced below), the Sonnenburgs gave some people probiotic capsules to see if supplements (like the bacteria in the fermented foods) would result in a more diverse microbiome with anti-inflammatory  benefits. They found that this was the case only for a minority of participants. Probiotics were beneficial only in the subset of people already consuming lots of vegetables and fruit. Thankfully, that does describe the majority of our functional medicine patient population, but it doesn’t necessarily fit most of the American public. This second experiment with the probiotics wasn’t published so I can’t comment on which probiotics were used, or how much benefit was derived compared to eating fermented foods.

Now that we know this, we can have some fun creating and consuming a wide range of fermented foods. We can circle back to raising the fiber in our diets when we get some better bacteria as a result.

FERMENTING

The simplest foods to ferment at home are from the cruciferous vegetable family. Many recipes are available online and in books on fermentation (a couple of books I liked are listed in the references below). Cabbage, cauliflower, kohlrabi, turnips, daikon radish, and others just need to be cut up, mixed with salt, and massaged for a few minutes. Liquid will appear as you do that, and you can stuff them into a jar below the level of the liquid if you push hard enough (usually). Then they need to be weighted down, with a glass weight, or a sterilized rock (boil it for 12 minutes). Finally, you want to place a permeable lid (I like airlock lids that let gases out but not in), and keep the mixture at room temperature, 60-75 F, for a few days. Taste them once a while and decide when they are done. You can add other vegetables to the mix, or ferment just carrots, onions, cucumbers, etc., but you’ll have to find recipes that tell you how much salt to use, and which starter culture to add. If you also add hot peppers, you can make kimchi.


Fermented drinks are also quite simple to make. You can place grated ginger and raw unprocessed sugar in a jar and leave the mixture at 70-80 F for a few days, feeding it additional sugar and ginger daily. This will create a “ginger bug” and you can use some of the liquid to make bubbly gingery drinks, while keeping the “bug” going over time.

If you purchase (or obtain from friends) a “symbiotic colony of bacteria and yeast” (SCOBY), either milk kefir grains, water kefir grains, or a kombucha SCOBY, you can turn milk, water, coconut water, nut milks, or tea into fermented drinks. The first fermentation (1-21 days, depending on the preparation and temperature) isn’t very bubbly, but then you can ferment your drink further in a sealed container (“second fermentation”), at room temperature, for 1-2 days, maybe adding fruit and herbs, to increase the carbonation and flavor. In other words, there is an endless world of creativity out there! The kefir grains and SCOBY are living organisms, so you have to figure out what to do with them to keep them healthy between making batches of fermented drinks.

One more option: fermented vegetable tonics. This is vegetable juice such as carrot or tomato juice or a mix, fermented at 65-75 F with the addition of brine from a previous ferment, for 3 days. This produces a highly nutritious drink — just 2 ounces constitutes a portion of fermented foods. There’s also beet kvass, which is cut up beets soaked in salt water for a few days. This can also be secondary-fermented into a more complex and bubbly drink.

HUGE VARIETY

Of course there is also yogurt, cultured cottage cheese, cultured cream, and butter. A recent report revealed that many commercial products do not contain the probiotics they claim to contain. Making these products at home could be one solution to this problem.
Meats can be fermented (salami, corned beef), as well as grains. Soybeans and other legumes, and hot peppers and garlic can be fermented into useful sauces. It’s truly endless. There’s even a book about fermenting wild radish seed pods and cattail stems.


With the Holidays almost upon us, we naturally think about all the multiple roles of food, nourishment, tradition, togetherness, celebration, and delight. It can be a good time to venture into learning about the playful art and science of fermentation.

Avoiding Antibiotics

1 Comment

Read Now
 
The Journal of the American Medical Association (JAMA) this week has 2 articles on avoiding antibiotics for childhood sinusitis.

One is a research article showing that there is no difference in the rate of symptom improvement unless the culture is positive for either Strep pneumonia or Hemophilus influenza, and only about 50% of the cases have one or the other of these.
It also reveals that the color of the nasal discharge is no help in telling us whether there will be any response to antibiotics.

The accompanying editorial goes further in saying that even when there is improvement, this improvement is not striking: it might be a slight decrease in the duration or the cough frequency, and in return, you get all the drawbacks of an antibiotic course. Read further for tips on avoiding antibiotics in several different situations.


Tips for Avoiding Antibiotics

By now, we’ve all heard that we need to try to avoid antibiotics. But did you know that at least 50% of all antibiotic prescriptions are unnecessary? This conjures up images of bored tired careless time-pressed doctors, but I think that is the wrong image. I think a lot of well-educated people who are otherwise getting good care are ending up on too many antibiotics because doctors don't have enough other tools.

The illnesses for which antibiotics are often not needed range from a variety of upper respiratory infections (bronchitis, sinusitis, pharyngitis and otitis), to skin infections, and perhaps urinary tract infections. In functional medicine, we almost always focus on improving the gut microbiome. Thus, I am often disappointed when, in the middle of trying to improve their inflammation, my patients unnecessarily end up on antibiotics!

The list of where antibiotics don’t help just keeps growing. We know of several conditions where antibiotics just set you up for the next infection by eliminating the beneficial bacteria that keep things in check.

Here’s what I would do for some common conditions:

1. Sinusitis

There is no evidence that antibiotics make a difference here. Whenever a study is done comparing different antibiotics and placebo, no difference is detected. Yet so many of my patients swear that they would get extremely sick if they didn’t have their antibiotics. So since sinusitis is a viral illness (unless you have a fever of 102.5); and since you can’t kill bacteria before they develop (resistant ones would develop in their place); here’s what I would like people to try before filling a prescription: an antiviral regimen. Purchase a bottle of Sambucol (NOT Sambucus) from Amazon ahead of time and keep it in your house in case you get a virus. At the first sign that you are coming down with a cold, take a dose of Sambucol and call me for a full antiviral protocol: it involves large doses of vitamin A, vitamin D, and other supplements. Let’s try to nip this in the bud and give you some strategies for the future.

2. Ear infections

While these are very painful, about 99% of them resolve on their own, and that is also true in most children. I like to use ear drops with garlic and mullein, and if the infections are frequent, look for an underlying cause of allergies, such as food intolerance, or a history of water damage in the home.

3. Skin infections

The first line of treatment for a break in the skin (a cut or abrasion) should be careful cleansing with soap and water, and very quick scrubbing of the area to remove dead skin. It is very hard for bacteria to infect live skin, but they go for those leftover bits if you are too gentle. Then elevate the area if appropriate, to prevent excessive swelling and give infection-fighting cells a chance to get to the wound.

4. Bronchitis

This is also almost always viral. The exception is for chronically ill people, such as long-time smokers with chronic bronchitis, who can get their diseased lungs infected with bacteria. The rest of us just get cough with phlegm (that is the definition of bronchitis). It does not matter whether the phlegm is clear, creamy, yellow or green – it’s all viral (rust or blood requires investigation). Make sure you drink plenty of water to keep phlegm thin so you can cough it out more easily. If you get bronchitis often, let’s look for an underlying source of inflammation. I know from personal experience that improving your overall health can eliminate bronchitis from your life completely. But please avoid antibiotics.

5. Bladder Infections

These are very common. They start with feeling like you need to urinate frequently, and a sensation of burning when urinating. Many women know to quickly get started on some cranberry concentrate, but don’t have any additional tools. When the cranberry fails, too many rush to their primary care provider, or even call and get a prescription over the phone. If you are at risk of urinary tract infections, please call me and let’s have a short visit. There are several treatments that would be appropriate for non-pregnant adults.​

So are they placebo?

While the effect of unnecessary antibiotics could simply be placebo, it does seem like it could be something else when so many people swear by them. One theory I have is that antibiotics make people feel better by changing the mix of gut bacteria. Perhaps there are other ways of accomplishing this! Get some rest; change your diet; take probiotics?

And in case you are wondering what else is overprescribed, here’s a list from the “Choosing Wisely” campaign, which attempts to improve the quality of care by physicians

7. Conjunctivitis: most pinkeye is also viral

8. Back pain: steroids do not work

9. Back pain again: MRIs rarely change management

10. Reflux in babies: antacids almost never work

11. Medications to bring down fever: almost never needed

12. Antibiotics for prevention of complications (for the dentist for example) when patients have mitral valve prolapse

13. Routine antacids to prevent ulcers in hospitalized patients


I hope this helps you keep your personal collection of beneficial bacteria happy and thriving!

Unconventional Longevity

4 Comments

Read Now
 
What might be a functional medicine approach to extending the "healthspan?"
Picture
Dr. Peter Attia, well-known to people interested in cutting edge science related to longevity, recently published his first book, Outlive, now a non-fiction New York Times best seller. The book is receiving mostly high praise on Amazon and Good Reads.
At this point, most people know the basics of longevity:
  • eat your vegetables
  • exercise regularly
  • treat known conditions
  • do preventative testing
  • don’t smoke
We also understand that we want to live not only longer, but also be as healthy as possible hopefully until the end.
Conventional medicine has long taught that there are actionable ways to avoid an early death. Public health has supported “health promotion and disease prevention,” and sets periodic goals for individual preventive services. The US Preventive Services Task Force publishes guidelines after reviewing the latest evidence. A service needs not only to be effective in reducing the harm from a certain disease, it also needs to not cause significant additional harm.


Medicine 3.0

I admit I have not read Outlive, but I have been a faithful listener of 250 or more of Attia's podcasts, since the first one came out in 2018. I am very familiar with his outlook and recommendations.
Attia introduces the concept of “Medicine 3.0.” The idea is that Medicine 1.0 is what happened when we found effective treatments for acute illnesses. Medicine 2.0, which is what most doctors are practicing, addresses chronic illness with certain medications. It also recommends certain diets (for example, the DASH diet for hypertension), and admits that sufficient exercise, stress reduction, and sleep are relevant to avoiding and managing chronic conditions. By Attia’s definition, Medicine 3.0 would build on its precursor by integrating advances in technology, data analytics, and systems biology to deliver truly personalized and precision medicine. Medicine 3.0 would leverage digital health technologies, artificial intelligence, and predictive analytics to optimize health outcomes and enable earlier detection and intervention. Under this banner, Attia also promotes the concept of “healthspan" extension, aiming to prolong healthy and functional life by targeting the underlying mechanisms of aging and age-related diseases.

Interestingly I don’t think this type of medicine is available, many of the tests may be used in research settings but not in clinical settings, and only a few people can afford all the high tech tools, some of which have no proven net benefit. Accordingly, the most common critique of Outlive appears to be that it fails to give practical information.

Picture

​Functional Medicine and the Healthspan


Attia is not trained in functional medicine, and what he recommends overlaps with but does not encompass all of functional medicine. For example, I have never heard him or any of his podcast guests mention that an “elimination diet” meant to improve the quality and quantity of gut bacteria can powerfully impact cholesterol, including his favorite metric, the apolipoprotein B. But I have observed this repeatedly in my practice. It is almost a surprise when it doesn’t happen. To be fair, there does not appear to be research on this, but I learned it from my teachers in functional medicine.

So as I scanned the several hundred reviews of Attia’s book, I wondered how the functional medicine approach to longevity and the health span would be different. The only study of longevity (actually using the Horvath clock as a proxy for longevity) showed that a specific diet (“Younger You”) resulted in the subjects becoming 3 years younger on average, after an 8-week diet change (Fitzgerald et al, 2021).

Functional medicine has called itself “21st Century Medicine.” The emphasis on lifestyle, systems biology, and abundant lab work is present in both functional medicine and Medicine 3.0.

However, functional medicine also emphasizes the following, and Attia fails to do so, in spite of the fact that there is reasonable evidence for their importance:
  1. Environmental toxins are playing a significant role in ill health, and this is gaining mainstream recognition (Lamas et al, 2023). We are exposed to neurotoxins, immunotoxins, endocrine disruptors, and carcinogenic substances. These need attention.
  2. Many people have inadequate nutrients. While conventional medicine focuses on a few (B12, iron, sometimes vitamin D), and Attia mentions folate and magnesium, we have good evidence for the importance of optimizing several others, including omega 3s, zinc, copper, calcium, coenzyme Q10, and DHEA (see references)
  3. We can improve gut bacteria and biomes throughout the body; there is definitely enough actionable clinical research on this (Wastyk et al, 2021)
  4. We can and should improve intestinal permeability; I don’t remember Attia ever discussing “leaky gut” though it is understood to be a cornerstone problem (Fukui, 2016)
  5. We need to look for and target common persistent infections: for example Herpes simplex 1 (cause of cold sores) is related to Alzheimer’s disease, and treating with antivirals when appropriate likely reduces the risk of dementia (Lopatko Lindman et al, 2021)


A practical proposal

So I would like to propose Medicine 2.5/Functional Longevity: something that uses the science we have, and the tools that are presently available to us, to design a root-cause, personalized approach to longevity and healthspan:

  1. Start with a complete patient history
  2. Add US Preventive Services Task Force recommended testing (mammography, colonoscopy, and more depending on age and sex and risk factors)
  3. Add basic blood testing that insurance normally covers, as justified by pre-existing conditions
  4. Add self-pay testing, depending on interest and level of evidence, including: levels of certain key nutrients, blood and urine heavy metal levels, levels of antibodies to certain common infections that might tell us whether they are still too active, and other actionable markers
  5. Consider microbiome testing: it is in development, but it is an option that can be explored. At any rate, some of the research-proven ways of improving the microbiome can be undertaken even without testing.
  6. Use available Medicine 3.0 tools, like the continuous glucose monitor, body composition DEXA scan, and the continuous monitor for heart rate variability, to gain insight into these important parameters
  7. Individualize diet recommendations
  8. Learn stress reduction tools: heart rate variability (HRV), a marker of stress, is related to many diseases and to survival itself. So we should be well-versed in ways to improve HRV. We have an option for continuous HRV measurement.
  9. Use low tech interventions optimally: overnight fasting is one such intervention. Attia does not recommend fasting for longer than 14 hours due to possible muscle loss. That is definitely something that can be individualized. Another is the fasting-mimicking diet: a tool for improving cholesterol levels, insulin resistance, and overall, favorably altering the microbiome to improve symptoms of various autoimmune diseases, and also response to chemotherapy (Longo et al, 2021)
  10. Individualize exercise. Attia spends a lot of time exercising, including several hours weekly in Zone 2 training (moderate intensity steady-state cardio). On the other hand, Stacy Sims, PhD, an exercise researcher who specializes in women’s physiology, says that Zone 2 training is not so important for postmenopausal women, while other types of exercise take on more importance. Too much exercise reliably brings on low heart rate variability, a risk factor for many diseases.
  11. Pay close attention to additional systems biology approaches, such as sufficient stomach acid, to make sure the stomach can serve all the roles it specializes in; dental care, hearing testing, eye care — senses are an important part of keeping the brain cognitively healthy.
Picture

The Root-Cause Approach

When it comes to the core parameters of longevity, functional medicine takes more of a root-cause approach than I ever hear discussed in Attia podcasts. Or sometimes, an approach that leverages the body’s pre-existing pathways to health. Here are some key parameters to optimize when aiming for a longer healthspan, and how one would address them using a root-cause approach. None of these work for everyone, and some should only be attempted after other steps have been taken.

1. Blood pressure: diet, exercise, elimination diet, stretching, nitric oxide supplements — and of course medication if all else fails. Treated hypertensives are never as healthy as normotensive people
2. High LDL or high apolipoprotein B: diet, exercise, fasting-mimicking diet, elimination diet, fiber, consider the impact of saturated fat, or the impact of carbohydrates
3. Homocysteine: B vitamins, elimination diet, omega 3 supplements
4. Glucose and insulin/insulin resistance diet, exercise, sleep, elimination diet, fasting-mimicking diet, stress reduction, improving HRV, increasing plant-based foods, ketogenic diet — it really depends on the person
5. VO2 Max: coenzyme Q10 and other mitochondrial nutrients, exercise
6. Bone health: calcium, vitamin D, exercise, diet, sleep, homocysteine, gluten-sensitivity, leaky gut and inflammation
7. Colon health: optimize gut bacteria, diet, exercise, elimination diet, probiotics, fermented foods, fiber (but in what order? That is dependent on the individual)
8. Muscle mass: exercise, diet (enough protein), reducing inflammation, sleep
9. Improving sleep: monitoring HRV, supplementation, making practical changes to sleeping environment and to preparation for sleep
10. Overweight: fasting-mimicking diet, 13-14 hour overnight fasting, elimination diet, exercise, toxins
11. CPR and other markers of inflammation: elimination diet, probiotics, sleep, stress reduction, exercise, cur cumin or anti-inflammatory herbs.

Patients on the Bredesen Protocol/ReCODE

23 Comments

Read Now
 
Dr. Dale Bredesen published his End of Alzheimer’s book about a year ago in the summer of 2017. The group MPI Cognition began referring patients to providers trained in the Bredesen Protocol soon thereafter.

I have begun work with close to 30 patients for either prevention or reversal of cognitive decline. I have learned many things along the way, and have streamlined my approach, introduced practices to make it more comprehensive, as well as interventions to get to the root cause of the dysfunctions that lead to cognitive decline.

There is so much to teach each patient that I have finally written a 70 page Handbook that provides much detail. It will soon be available on this website for $9.95. I will update the link when I upload it.

Here are some lessons I have learned.

THREE ASPECTS OF COGNITION
I’m not talking here about underlying causes, but about what it looks like on computer testing.
We use online computer cognitive testing to understand the pattern of people’s cognitive struggles. The program is called “CNS Vital Signs.” It is a only a 30-minute assessment and therefore cannot give us nuanced information. However, people seem to be declining in one aspect of cognition and sometimes not the others, as far as I have been able to see. It tends to be one of the following:
  • the speed of understanding, processing information, and responding: low scores in scales such as “motor speed,” “reaction time,”, and “psychomotor speed.”
  • the formation of memories: “verbal memory” (remembering words) seems to sometimes behave quite differently from “visual memory,” which is memory for going back to places you’ve previously visited, and remembering where you parked your car.
  • organization, focus, attention, reasoning

WHO IS AVERAGE?
Many people who come to my office to optimize cognition were previously functioning at very high levels, typically in the “above average” range. Scores in the “average” and “below average” category for them represent cognitive decline. The good thing is that they are still in a position to partner with me to understand and be motivated to follow the program. They are not dependent on their spouse or adult child.

If I’ve learned anything, it’s how much easier it is to do this work when the decline is still relatively mild.


WHAT HAPPENS ON THE PROTOCOL
The first few weeks after the initial visit, people are often overwhelmed and confused. The testing we use is complicated and unfamiliar. We have to be in contact so I can answer questions and we can move forward. Thus I have now added an hour to go over the report and recommendations from the first visit.

At the results follow up visit, we go over test results and I show people what we will address first and how. Within a few more weeks, we see changes in energy and in any chronic medical conditions.
Subsequent visits see us revisiting the basic medical issues, “deprescribing” (getting off) medications that stand in the way of health, and adopting protocol recommendations as new lifestyle habits. We also see new problems emerge and have to address those.
Most people say they are thinking better within about 2-3 months. Memory has improved: how quickly people can access words that used to escape them, or the ability to multitask, engagement with other people, sleep, headaches sometimes, digestion almost always, anxiety level sometimes, and overall energy often.

I have follow up data on only 4 patients at present. The improvements so far are very exciting and we’re not even done! I will tell each of their stories briefly in the next blog post.


THE SPEED OF NERVE IMPULSES
I worry that people with below average motor speed or reaction time will be at high risk of falls, injuries, or if they are driving, of auto accidents. One of the correlations so far has been the role of toxins. I often see high lead and mercury levels among patients seeing me for cognitive decline. I had not seen such high levels with patients who were not affected cognitively. Indeed there is research to show that lead (from the leaded paint and gasoline of the past, or from recent exposures such as working with stained glass, handling ammunition, and others) actually slows down impulse conduction speed from one end of the nerve cell to the other. Neurons talk to each other slower. Thus of course one perceives the world slower, processes inputs slower, and responds slower. When that gets much too slow, organization and memory are affected too. Literally people seem to be forgetting what they were about to do.

There is evidence that carefully removing toxic metals leads to an improvement in this process. I have not yet had the chance to verify this for myself because it takes 9 months to a year to significantly reduce heavy metals. And before I even start the process, I have to make sure a patient is healthy enough for the testing itself (testing can involve the use of a medication that chelates heavy metals, that is it goes looking for them and pulls them out, and if it finds a large quantity, we can measure it in the urine). Treatment involves removing these metals a little at a time so they never overwhelm the body’s detoxification capacity, as they would redistribute and cause further harm. It is done through a combination of sweating (infrared sauna for example) and the use of supplements, herbal remedies, and medications.


PRESENCE OF SEVERAL UNDERLYING CAUSES AT ONCE
All my cognitive decline patients have several harmful processes going on at the same time. The groups defined by Dr. Bredesen are a good framework for me, but none of my patients have had only inflammation, or only high blood sugar, or only lead or mold. My sense is that by themselves, these may cause illness, but rarely cognitive decline. For example, I would see patients with leaky gut and fatigue or joint pain, or autoimmune disease, but mentally they were as sharp as ever.

In my experience, cognitive patients have a pile-up of several impacts, and I believe they all contribute. Patients are typically inflamed: one patient has celiac disease, several had very high levels of antibodies to gluten. They typically also have excess glucose, some vitamin deficiencies, a few hormone deficiencies, and most likely either a heavy metal, mold exposure, reactivated Epstein-Barr virus, or exposure to Lyme disease. While it is conceivable that some of these impacts are not bothering them, I don’t see how I can leave any in place and just work on others. I believe that what I am seeing is that while there are many paths to becoming cognitively impaired, it isn’t actually noticeable until a critical mass of body functions are affected.

I have seen patients come from other providers who were not thorough in addressing all the pieces above. I think that is unfortunate because the longer we wait, the harder it is to reverse the damage already done. Having seen the number of different things that are wrong with each person, my concern would be that I am doing too little, not too much, from the start.

I have also seen patients come from providers who were not using the “optimal” ranges for lab values in Dr. Bredesen’s book. I don’t think we have the luxury of relaxing these ranges, quite yet. Just my 2 cents’. I also worry about the use of weak supplements, doses that are too low, or herbal shortcuts. I fear that even if they work, these leave people vulnerable to setbacks.


THE NEED TO USE FUNCTIONAL MEDICINE
The dysfunctions we uncover are all related to each other. For example, the most significant cause of high blood glucose is inflammation. The most common source of inflammation is increased intestinal permeability (leaky gut). Patients with excessive intestinal permeability cannot efficiently detox heavy metals, and other toxins. Heavy metals of course cause high blood glucose, and inflammation. So the patients are running several sets of interlocking vicious cycles, and the work we do is to extricate them systematically from these situations. Thankfully, functional medicine offers guidance for this. None of these links are commonly recognized or addressed in conventional medicine. I don’t believe I could do this work without an excellent foundation in functional medicine.

In addition to interlocking vicious cycles, patients are also on medications that lock in their dysfunctions. For example, many have heartburn and take proton pump inhibitors, which worsen the absorption of a number of nutrients. The first job is to heal the underlying cause of the heartburn. This has to happen as we replenish the most critical nutrients and reverse inflammation. Again, the functional medicine tools allow me to move forward. Before I studied functional medicine, I used to have patients on chronic proton pump inhibitors that simply could not get well. I did not know how to guide them to digestive wellness.


MAKING AND KEEPING PEOPLE WELL
We have to find alternatives to conventional medical treatment that work just as well if not better. For example, it won’t do to put patients on non-steroidal anti-inflammatory drugs (NSAIDs), on acid blockers, on anti-anxiety medications, on medications for sleep, on statins (they worsen glucose regulation, harm mitochondria, and interfere with myelin synthesis), on antibiotics (unless there is a life-threatening situation), and more. But we can’t leave people untreated for any of the conditions for which these would normally be prescribed. Again, functional medicine comes to the rescue: these conditions have diet and lifestyle solutions.

We have to keep patients safe while they are focusing on reversing their cognitive decline. Fractures, surgeries, illnesses, stressful life events, new mold or Lyme exposure, and ongoing environmental toxin exposures, all must be avoided if at all possible, or their impact must be reduced. It becomes necessary to discuss how to avoid household toxicants, how to avoid getting colds, how to better address a conflict with another person (all that is in the e-book), and more.

At the same time, our interventions must be safe. Many patients need to start a ketogenic diet, because ketones are a better source of energy for the brain in decline. But the ketogenic diet clearly poses major challenges. Excessive weight loss, loss of enjoyment, friction with family and friends, and loss of social contact due to not being able to enjoy some of the previously enjoyed foods - all these can be harmful.

We need to proceed efficiently, cautiously, quickly, be comprehensive, incredibly organized, forgiving, optimistic, strategic, and compassionate. I won’t lie, it is a challenging field!


CONCLUSION
I’m in awe, every day, of the dedication and sense of agency of my patients. I hope that everyone at least learns about this protocol so they can take immediate action when they suspect the start of cognitive decline. We should remove the stigma of impaired cognition, so we can address the topic with each other and support each other in making lifestyle changes. I believe this is what we all have to do to create the end of Alzheimer’s.

Group Programs to Reverse/Prevent Cognitive Decline

52 Comments

Read Now
 
Since training with Dr. Dale Bredesen, and since the publication of his book, I have seen more than a dozen patients wanting to focus on cognition. It is not an easy program, but patients are feeling better in a variety of ways, and some are starting to feel cognitively sharper as well. It is a long program, and there are many aspects to look at - after fixing the nutrient deficiencies and the hormone imbalances, many people need more work on heavy metals, mold and chronic infections.

TWO PROGRAMS
I am launching a group version to try to lower costs for people who are having fairly mild symptoms. There are two programs.

PLEASE NOTE!!
  1. If you are in danger of losing your work or other important part of your life, please seek out a practitioner as soon as you can. The list of practitioners is available from MPI Cognition, as well as on the Institute for Functional Medicine web page (you have to look up individual practitioners in your area).
  2. If you have serious medical issues (insulin-treated diabetes, recurrent hospitalizations, severe illness from exposure to mold) you will not want to wait to follow a treatment plan online. By necessity, the online course will be slower and less well-targeted to your needs than any work with a good local practitioner.
  3. If you have the funds available, the online course will not be better than a local practitioner. 

FOR LOCAL RESIDENTS
For California residents who live locally here in the San Francisco Bay Area, and are willing to drive to my office, I am offering a two-part program consisting of the following:

1. An initial day long class that will involve detailed discussion of the protocol, individual visits with me, individual cognitive testing using CNS Vital Signs, and ordering of lab testing appropriate for each person's situation. Access to high quality affordable supplements will be offered.

2. A second day about 2 months later, to go over the lab results as a group and explain what to do for each one, answer questions, and finish explaining details of the protocol. More supplements are often used at this stage.

The cost of this program is $1200-1400 per participant, provided we can put together enough participants. I will ask patients to fill out questionnaires ahead of time, and I will spend 20 minutes with each person and give you requisitions for labwork and supplements at reduced prices, optimizing costs.


FOR PEOPLE WHO ARE NOT LOCAL
For patients who live too far to attend a local course, I am offering an online course with monthly group video calls for 1 year. That will take people step-by-step through the entire Bredesen protocol. In this case, patients will have to use their local providers or other methods to get lab testing ordered, as I cannot order testing for patients who are out of state. Also, while this may help a person diagnose a problem, like leaky gut or mold illness, these diagnoses don't always resolve well with self-treatment and may require a local provider in addition to the online course.


FOR PEOPLE WHO ALREADY HAVE A BREDESEN-TRAINED PROVIDER
The online course may be helpful in supporting anyone who is already doing the Bredesen protocol with their local provider.

I will go over this online program in more detail in a free video broadcast January 10 at 5 PM Pacific time. The link to this video is here. There will be no video playing in this spot until the date of the video, but then if you have missed that time you can watch the video at the same link anytime after January 10.

The online course costs $500 per participant, assuming we can enroll enough participants.

CONTACT US
There is much interest, and we are starting small. Please leave your email address here to a newsletter list that will focus only on group programs to reverse/prevent cognitive decline.

Please sign up here if you are interested in updates about these programs

Today is the first day of a series of videos about preventing and reversing cognitive decline. The website is here:
http://event.awakeningfromalzheimers.com/

Today's episode was a start, briefly discussed the importance of reviewing a person's medications to make sure there isn't a combination that might worsen cognition, and the importance of optimizing blood sugar and sleep. I believe this is going to be worthwhile, and easy to watch. There are many episodes, and it will be an investment, but so far, it looks informative.

The End of Alzheimer’s by Dr. Dale Bredesen: A Book Review

362 Comments

Read Now
 
Picture
In November 2014, neurologist Dale Bredesen M.D., published the first article on reversing cognitive decline. Using a combination of approaches centered on lifestyle and supplements, 9 out of a total of 10 patients reversed their dementia, and 6 of them even went back to work (1).

I was very excited when I read that article, especially because Dr. Bredesen’s approach fits so well within a functional medicine framework. I couldn’t wait to put it into practice and wrote a blog post about it (some-approaches-can-reverse-cognitive-decline.html).

Since then, I have taken Dr. Bredesen’s 3-day training for health care providers who want to apply the Bredesen protocol (now called “ReCODE”, for “reversal of cognitive decline”). I have also been seeing several patients for a few months and noticing some encouraging early results. A few patients are just starting to receive results of blood tests that will help us focus our efforts at reversal.

In August 2017, Dr. Bredesen published his book “The End of Alzheimer’s: The First Program to Prevent and Reverse Cognitive Decline.” The book promptly sold out on Amazon but should be in stock again in early September. It is also available as a Kindle version, which is what I got. Though I had already spent many hours studying this information and organizing it to make it usable, I still found the book highly valuable. I also read it with an eye to considering whether it might be possible for many people to implement ReCODE on their own.

WHAT YOU NEED TO DO
What is the ReCODE approach? Basically you put into place universally beneficial habits (sleep, exercise, diet, stress reduction), and add supplements, alongside repairing dysfunctional processes (digestion, hormone function, processing of toxins) to the point that a number of blood test values are “optimized.” The ranges used by conventional labs are not sufficient here – we are looking to reverse illness so everything has to be “optimized.” And then you add supplements and herbs which in sufficient doses are known to enhance cognitive function. As you will see, the devil is in the details, but if you understand cognitive decline, it’s obvious that this would be the way to go.

“The End of Alzheimer’s” starts by reviewing the current beliefs about dementia – as summarized, for example, on the web page of the Alzheimer's Association – stating that basically, Alzheimer’s Disease is considered incurable and lacks effective medications to manage its symptoms. A search for “Bredesen” on the Association’s website turns up some references to grants from a decade ago, focusing on basic research rather than clinical research. I could not find the 2014 article mentioned above, and the subsequent clinical articles authored by Bredesen (2), (3).

One chapter of Bredesen’s book focuses on how a dementia patient feels. I loved this analysis: until now, people were not able to report on how things felt while they were in the throes of this disease because they never regained enough clarity to make the comparison. There’s nothing more compelling, once you have recovered a function, than to look back and remember how things were when you had lost it. For example, “Eleanor” recounts:
  • “Before I reversed, it felt like I had a filmlike gauze over my brain that kept me from really connecting with others and from being able to easily engage in normal conversational back-and-forths. […] I couldn’t have told anyone that all these things were problems last year. I couldn’t put it all together.”
I found this section deeply moving: this is why my colleagues and I are in practice, to make an impact as meaningful as returning a person to their life, their work, and their connections with loved ones. Witnessing that never gets old!

WHAT NOT TO DO
Another chapter outlines what most people do wrong that causes them to get ill, and much of it applies to Alzheimer’s, other dementias, and other conditions that involve inflammation (which is most other chronic conditions, from depression, to autoimmune disease, to joint and muscle pains and digestive issues). It's a funny chapter, and also poignant, because it describes the way we functional physicians go through life – seeing hidden dangers where there was previously routine: the morning mocha and danish pastry, tuna sandwiches, diet sodas, afternoon candy, pasta dinners, and mildewy basements. I have to admit, those were almost daily “exposures” for me for decades. Dr. Bredesen writes:
  • “The bad news is that the more you see yourself in the lifestyle I described, the more certain you can be that it is already impairing your mental sharpness.”
Actually, I would say, that is the good news. I know firsthand how good it feels to improve your lifestyle even partially. Many people come for a consultation because they are in pain and fatigued, and also concentrating poorly and feeling apathetic. They are not yet demented and there are many steps we can take to prevent that from happening. But their early on-course indicator and source of motivation is that they soon begin to feel better in a variety of ways. It doesn’t always require a complete life transformation. Our bodies can be quite forgiving, and having witnessed this repeatedly, I have no trouble believing that we can reverse dementia.

A theme throughout the book is the near universal negative reaction of respected neurologists and people’s primary care physicians. It seems hard to believe that medicine would be so rigid, but at the same time, that is not entirely a bad thing. It would be a problem if we adopted new treatments without giving them much thought or study. However, from the point of view of functional medicine, a ReCODE type approach is completely in keeping with what we normally do successfully in pursuit of reversing other illnesses. The skepticism toward ReCODE is the same as that regarding reversing type 2 diabetes, or hypertension, or arthritis. Most people’s primary care and specialist physicians are very critical and remain in disbelief. Strikingly, they do not reach out to us to investigate, as though they were not interested. But I believe instead that they simply don’t trust themselves to figure out if something is really working: they would rather wait for an official guideline. The problem with dementia, as with many of the other “incurable” illnesses patients face, is that patients don’t have years to wait, and may even have lost faith in a system swayed by big business interests.

Picture

​THE SCIENCE BEHIND THE BOOK
Part 2 of the book delves into the science that explains how dementia comes about, and thus how these problems can be tackled and reversed. The science is very well laid out, with useful metaphors – some of which I immediately adopted with my “cognitive decline” patients. I find that knowing how something works improves my motivation to implement a complicated program. Dr. Bredesen compares cognitive decline to the “roof with 36 holes:” it’s raining in your house because the roof has many defects – not just a few. If you fix just two or three, it will continue to rain in your house. Another way I understand it is the problem of “feed-forward cycles” – to interrupt a negative feedback loop, you just need to stop one event from happening. But in a system of interconnected feed-forward cycles, you have to stop most of the links.

So ReCODE is very much the inevitable conclusion of Dr. Bredesen's years of basic research. The novelty here is not the belief that mercury, or mold, or B vitamin deficiencies, or lack of thyroid hormone, can cause dementia. These are well-established medical facts. The novelty is in demonstrating that even small alterations in these parameters (being in the “normal,” but not the “optimal” range) can add up and create devastating decline. Reductionist clinical experiments, where only a single parameter is changed, will often have negative results where a combination of changes would have succeeded. But that, again, is functional medicine, and Dr. Bredesen admits that he was influenced by his wife Aida, an integrative physician. It is Dr. Sid Baker’s old metaphor: if you’re sitting on three thumb tacks, removing one will not make you feel better. The argument from the conventional medicine side is that big enough studies will include enough patients who are lacking only one aspect to get picked up in the statistics. Unfortunately this is not how Alzheimer’s disease develops: you often need more than one impairment to develop it, and reversing it requires you fix them all – thus very few people get better when you address only one of their impairments.

In the book, you will learn about three major types of Alzheimer’s disease, as well as type 1.5, which combines type 1 and type 2. These three types are the ones most easily reversed. Now you begin to have a framework for the tasks that lie ahead, but it will require first figuring out what type you have, and this means laboratory testing.

NUTS AND BOLTS
There is no reason your primary care provider cannot order all the laboratory tests suggested in the book and use Dr. Bredesen’s optimal ranges to pinpoint sources of problems. There is a skill set that comes with fixing some of these deficiencies, but it is certainly a good first step to identify them. Insurance sometimes pays for this, and flexible spending accounts may cover the supplements that help address some of the problems found. But your physician will likely not order and interpret lab tests simply based on a book, because as I mentioned earlier, they are most likely waiting for an official recommendation from the American Board of Internal Medicine, Board of Family Physicians, or equivalent neurology association. And the expert panels are not yet convinced.

So, the question arises as to how realistic it is to think that many people would navigate this protocol on their own. It is a complex endeavor in the face of an emotionally charged situation. Nonetheless, some patients have done so, and I can’t think of any other way to bring about change than to empower patients to feel hopeful, and to pressure their physicians and insurance companies politely and persistently until more get on board.

By combining several direct-to-consumer sources like 23andme and DirectLabs or RequestATest, one can make some headway, assuming hormone status is optimal. If hormone therapy is needed, a physician's prescription for thyroid hormone, for estrogens, for progesterone, and/or testosterone will be required, and any physician would first have to be convinced that they are needed and safe.

The services of a Bredesen-trained health care provider can be expensive, so I would love to see a calculation of how much money patients save when we use tricks we know for less expensive lab tests, specific supplements. We also use our experience and expertise to avoid going down wrong paths. If anyone has already calculated the cost of getting these labs without a physician, please leave a comment.

I used a random few labs to get a quick sense:

TEST                                    IN MY PRACTICE    IF PATIENT ORDERS
total T3                                  $0-4                         Direct Labs: $49
free and total testosterone    $0-15                        Direct Labs $79
Hemoglobin A1C                   $0-4                         Direct Labs $119
Homocysteine                       $0-4                          Direct Labs $69
ApoE4  genetic test              $1-50                        $199 for 23andme

I believe you will spend a lot more ordering labs on your own than through a savvy functional medicine provider, perhaps in the order of $2000 more. Also, you will not be able to get all of them: I could not find the innate immune labs required for a diagnosis of mold impact on Direct Labs.

I imagine that Dr. Bredesen could not write a book where he tells people to go see a functional medicine physician (though he does provide a link in Addendum A). And the truth is I am hopelessly biased, as seeing individual patients is in fact how I make my living. But do take a look for yourself, and make your own decision.

Some of the tests mentioned do require a physician who knows enough integrative medicine to know of (and believe in) testing using Cyrex Labs, interpret integrative stool testing, prescribe the chelator for the urine heavy metal testing, etc. You may need a provider who knows how to take patients off proton pump inhibitors, how to control blood sugar and reverse prediabetes, how to use a low carb/high fat diet safely, treat for mold illness (CIRS – chronic inflammatory response syndrome), Lyme disease and co-infections, and mercury overload.

Those of us who practice functional medicine have had to learn each of the above since our graduation from medical school, as well as keep up with advances as would be required of any physician. The 25 annual hours that are mandated in order to keep our licenses fall far short — this is why we can’t accept insurance rates of reimbursement that are based on a model where a physician sees 20 patients a day.

HOW TO PROCEED
I believe that any hope of making ReCODE more affordable might lie in setting up group visits. Especially at first, it could be much more cost-effective to go through the evaluation and intervention with a group of patients and their caregivers. This will require that enough patients reach out to us to start setting up these groups. Some of my colleagues dream of a ReCODE “center,” where patients could go and attend a series of classes, be seen by physicians in a cost-efficient manner, and quickly be on their way to improving cognition.

“The End of Alzheimer’s” goes on to discuss the steps necessary to follow the protocol in great detail, and some common problems faced by those who have. In person, Dr. Bredesen is positive, encouraging, hopeful. He has witnessed miracles after a professional lifetime of seeing drug treatments fail. He has worked all his life to understand this disease, and the solution to the problem turns out to be a complicated one. As in other endeavors in life, it’s of little use to wish for what is not true to become true. Instead, we ought to “turn around and face in the direction the horse is going.”(4) This is one disease that cannot be solved by a single cutting edge pharmaceutical agent, not in 2017, but you don’t have to just decline and suffer. Commit to the  ReCODE protocol for 6 months, and then decide if what you lose in implementing ReCODE is worth the bargain of saving your brain.

ONLINE APPROACH
I have put together a video outlining how I plan to structure an online course to take patients through a protocol to reverse/prevent cognitive decline structured on Dr. Bredesen's approach.

What do we really know about vitamins, supplements, and performance enhancers?

A 2016 Frontline special was highly critical of the vitamin and supplement industry, pointing out that it is largely unregulated, that supplements are not proven to be useful, and that some people have become quite ill or even died due to a supplement they were using.
​

I actually agree with much of what they discussed on the show. The only thing I thought was a strange omission (given the topic) is that they never mentioned that we do have some independent third party testing for supplements, through ConsumerLab and LabDoor. Frontline also downplayed the known benefits of vitamins and herbs. For example, they never mentioned that in a 2012 research paper, 14,641 male physicians were randomized to receive a multivitamin or placebo, and followed over 10+ years. The group that took the vitamin had an 8% reduction in cancer.

So vitamins may be poorly regulated but they are worth looking into.


Moreover, contrary to Dr. Offit's assertion that most of us are getting enough vitamins, the US Department of Agriculture freely admits that most Americansdo not consume sufficient quantities of many vitamins. Right at the top of the list, only 46% of Americans consume enough vitamin A. 13% consume enough vitamin E. So, do you need to take vitamin supplements? How will you figure this out?


CLARITY IS POSSIBLE
I would like to help bring some clarity to the situation. That would take writing a book of course, but here are a few thoughts. I come at this from a very strict conventional medicine background. I practiced as a conventional family physician for 20 years (1987-2008) and during that time did not use or recommend any preventative vitamins.
When I “discovered” functional medicine, I decided to suspend disbelief and try the supplements recommended by Dr. Mark Hyman in The Ultramind Solution. I was really amazed to feel that they were helping me (that was not a scientific observation, but an intuitive one). I then joined a group of physicians who were all to some extent transitioning from conventional to functional medicine, and we formed a “lab group” so we could share our experiences with the myriad of new and unusual tests that we saw being used by alternative medical providers. Which ones were reliable? We really wanted to know. Having followed a flawed recipe for health during our time in conventional medicine, we were quite determined to figure out how to provide the best care for our patients.

WHAT ARE ALL THESE PILLS OUT THERE FOR?
I see five basic types of pills sold without a prescription:
  1. One type involves substances our bodies already make, such as coenzyme Q10.
  2. Another type involves substances that are not normally part of the body's biochemistry, but that we hope will modify the chemistry in a specific way. This is true for over-the-counter medications like antihistamines and anti-inflammatories, and substances derived from herbs and spices, like turmeric, cinnamon, Saint John’s Wort, rhodiola, red yeast rice, and many others.
  3. There’s the category of "essential nutrients," which includes omega 3 and other fatty acids that are normally in food, but can be hard to get for some people.
  4. There’s a group of substances I will call performance enhancers: these are designed to jolt the system, to make you lose weight, to build up muscle, or to increase sexual performance. These are the group of supplements one should never take because they are by far the most likely to result in injury or death. These supplements may actually contain unlabeled drugs, like Viagra or steroids, and they also may contain known toxins that may help temporarily but have been banned for being harmful.
  5. Finally, there's vitamins, which are substances that are absolutely necessary and that our bodies usually cannot make. Most of these should be obtainable through food but there are three reasons why people may not have enough:
  • They don’t eat the right foods
  • Genetically, they need much more than can be obtained through food
  • They have a condition that causes them to require a supplement
Over the last 5 years of training and practicing as a functional medicine physician (2010 to present) I have developed the following guidelines around vitamins and supplements.


RELIABLE TESTS
First there are some substances for which there are reliable tests. These include coenzyme Q10, vitamin D, vitamin B12 (though you need to check a methylmalonic acid, the B12 level is not sufficient) and other B vitamins (measured indirectly using the serum homocysteine – not perfect, but if too high, you know you need them – usually).
The reason to test and treat for these is that insufficiency either causes fatigue and difficulties with the immune system, or may cause a number of problems in the future. The most important issue is prevention of Alzheimer’s Disease. This is such a long latency disease that our main focus is prevention (though it can sometimes be reversed with a functional medicine approach). Proper vitamin levels may not be sufficient for prevention, but they provide some insurance.
There’s a few more nutrients I can test for reliably, including zinc, iron, selenium, and essential fatty acids, including long-chain fatty acids (omega 3s, omega 6s, arachidonic acid, etc.) and short chain fatty acids (made by beneficial bacteria).
Cholesterol is another nutrient we can measure. LDL cholesterol, often called “bad cholesterol”, is actually the building block for many critical structures: cell walls, myelin sheath for nerve cells, and steroid hormones like estrogen, testosterone, progesterone, cortisol, vitamin D and thyroid hormone. So how “bad” can it be? Well, there are many sizes of LDL, and it can be in a normal state, or an oxidized or glycated state, and each of these sizes and states matter to cardiovascular health. We can measure all these, and it’s not expensive, but it is often not done.


LESS RELIABLE TESTS
There are nutrients one can only hope to get a good handle on: these include vitamins A, C, E, and magnesium. It seems you can best measure these indirectly, by looking at levels of certain metabolite levels (body substances), or at damaged cell structures, like lipid peroxides and the level of 8-OH-deoxyguanosine, a cancer predictor.


UNRELIABLE TESTS
Finally there are nutrients that we really can’t measure. For example, there are many tests for iodine but none are reliable indicators of deficiency or sufficiency. I used to like the serum iodine but now I am not sure it’s the best way to go. Experts in the supplementation field recommend a careful trial of iodine rather than testing. 
Many tests attempt to quantify beneficial bacteria and I am not sure we are really getting a good picture from them. The situation is so complex, some won’t grow in culture, and the techniques for detecting them are imperfect. In research, arrays of beneficial bacteria seem to have a tantalizing story to tell but in individual patients, I can only make out very broad generalities. I actually like to look at their output (the short chain fatty acids they synthesize) better than their presence or absence. 
Calcium levels are available but they tell us more about abnormal hormonal conditions or dangerous cancer side effects than about dietary calcium sufficiency. Whether calcium sticks to bone or not seems to depend more on just about everything else: fruits and vegetables in the diet, level and type of exercise, gluten sensitivity, etc. Calcium is also important for cardiovascular health, and it is true that if you consume no dairy and few vegetables, you are likely to be deficient.


GAMING THE SYSTEM
I use just a few herbs because to me they are in the same general way of thinking as medications. They may be better suited to our body than manufactured chemicals, They may sometimes accomplish what medications can’t. But in general, they are not a root-cause solution.
I use some herbs that help reduce the impact of stress while someone is recovering from a long series of stressful events that have impacted the functioning of the adrenal glands. But along with these, I use stress reduction practices and tools to change how we respond to what bothers us.
I use turmeric or a combination of anti-inflammatory herbs to try to get someone off anti-inflammatory medications which can cause intestinal permeability (and a vicious circle of inflammation). I’m sure some people need to stay on turmeric, in certain situations where damage will not completely resolve.
I use red yeast rice when the harmful type of LDL cholesterol won’t resolve in spite of reasonable efforts with a functional medicine approach. There are many natural substances one can use to alleviate symptoms while we attempt to heal the underlying systems: inositol, N-acetyl cysteine, acetyl-l-carnitine, alpha lipoic acid, and many, many more. So many in fact that this is a significant problem with the first phase of functional medicine treatment: having to take so many pills. The goal is to get to a final minimum, or even to stop taking them altogether.


VITAMINS FOR HEALTHY PEOPLE
If you have no symptoms, no fatigue, no digestive issues, no joint pains (my three favorite symptoms to reverse!), no autoimmune disease, no strange neurological sensations, no mood or mind issues – should you still take a preventive vitamin?
There are two things you can do to answer this question:
  1. See a functional medicine provider you trust for an assessment. Discuss your diet, your habits, your family history, get basic labs, and decide. The aim would be to avoid a long latency disease or an autoimmune disease that has not yet occurred.
  2. Try a set of basic vitamins and take them for 3 months. Religiously. Keep track of any observations. Then decide: was it worth the effort and cost? You won’t really know what you might need, but you will have tried to figure something out.


DO VITAMINS/SUPPLEMENTS CONTAIN WHAT THEY CLAIM?
Here’s one last problem, in fact they sometimes don’t contain what they claim to contain. If you see a functional medicine provider, she will in fact tell you her favorite brands. Ask how she knows: does she read ConsumerLab or LabDoor? These are third party testing organizations that try to find out what is in vitamins and supplements, and whether they may be contaminated with lead (which can be a problem for herbs, for example). If you are on your own, you may have to get a subscription to ConsumerLab just long enough to figure out a specific set of vitamins and supplements.


MY FAVORITES
Well, my favorite types (because my favorite may depend on the condition):
  • a multivitamin containing 5-L-methylfolate (not folic acid); and some vitamin A in retinol form
  • additional vitamin D3 to a total of about 4,000 or 5,000 units for most people (know your level!)
  • probiotics (at least 4 different strains each of Lactobacillus and Bifidobacter); 25 billion or so
  • omega 3s (at least 1000 mg of EPA+DHA from the Supplement Facts label, and only if third party testing says they have no heavy metals and PCBs, and are not rancid, and they don’t give you the fish burps when you take them)


CONCLUSION
Why would Frontline present a documentary with such frightening headlines? Will supplements make you sick? If you avoid performance enhancers and get advice from a provider you trust, or use the resources that exist for assessing the adequacy and safety of vitamins and supplements, you would likely come out ahead. It’s not dangerous, but it does take some work to figure out. On the other hand, I hate to say it, but pharmaceutical companies have been trying to get the supplement industry regulated so they can take over. One problem they face is that the medications they promote themselves have very high rates of adverse effects: in 2009, the Drug Abuse Warning Network calculated that 50% of nearly 4.6 million drug-related emergency room visits were attributed to adverse reactions to medications taken as prescribed!! Dr. Paul Offit (interviewed on the Frontline documentary) is well aware of this, as his own Rotavirus vaccine is known to cause a very dangerous condition called "intussusception." But he is essentially employed by a pharmaceutical company that funds the “chair” he sits in and the Institute he created, and perhaps prefers to talk about the side effects of vitamins rather than the side effects of pharmaceuticals. We need to be careful what regulations are put in place, or only well-funded Big Pharma will be able to sell vitamins. The problem is that some of these pharmaceutical companies have a long history of hiding research findings and promoting their products without following regulations. So, yes, we need to fix the system we have, but let's be smart about it.

New Study Shows Importance of Organic Food

8 Comments

Read Now
 
AND OTHER REASONS TO BUY ORGANIC

Should you eat organic? Should you choose organic meat, or fruits and vegetables? Are the “clean fifteen” OK to buy “non-organic”?

It’s hard to answer these questions without a point of reference. What are your goals? How did you come to adopt these goals? What are the underlying questions?

We have grown used to inexpensive food (compared to other nations) to the point that our household budgets are dependent on it. However, there are many reasons to make a change, and not only for the most heavily contaminated “dirty dozen” crops.

Here are some of the reasons to prioritize organic food:

1.      Organic food is better for your health. We finally have a study that followed 35,000 Danish women through pregnancy. Women who ate mostly organic foods had half the chance that their baby boys would be born with a birth defect called hypospadias. This defect involves the development of male reproductive organs, which are sensitive to the hormone disrupting effect of many pesticides.

2.     Organic food is the moral thing to do: we have solid research indicating that children of farmworkers, and children in farm areas, are affected by the pesticides we use on our food. If there were less such food, these impacts would be lessened. Our choices affect others’ lives.

3.     Healthier farm children translate into lower health bills for our nation, and improved school scores, and hopefully an improved workforce. ADHD, for example, can lead to increased rates of low school achievement, drug use, truancy, and arrests. We should all care about outcomes for farm children.

4.     Pesticides are affecting our environment: actually, few disagree on this point. Do we think that the destruction of our environment will never impact our own health and happiness? Of course it does. We are part of this ecosystem. For example, if bees become extinct, our food supply will be threatened. We should boycott all products raised with the use of neonicotinoid pesticides. Now. The world needs bees, we can’t afford to wait for scientists and businessmen to agree.

5.     The old saying that “the dose makes the poison” is now believed to be false in many cases. You shouldn’t believe anything you read that relies on this argument. Unfortunately, many chemicals that affect our hormones work more powerfully in small doses than large. How can this be? Simple. These chemicals interact with receptors in our bodies. The receptors adjust to the level of chemical in the environment. If there is a low level, they accept the chemical and become affected by it. If there is a high level, they inactivate and stop becoming affected. Many chemicals were initially tested at high doses because we were looking for cancer-causing potential. Once they were found to be hormone mimics, the rules changed. They must be shown safe all over again, and many simply haven’t been tested.

6.    Our regulatory agencies never thought that the effects of chemicals would pile up on top of one another. They somehow thought that if each chemical is at a safe level, then the food is safe to consume. But the truth is that the effects of chemicals add up on top of one another, even if they act on different biochemical pathways. It seems prudent to avoid chemicals where we can, even if their individual levels are deemed safe. 

7.     I sometimes see journalists make the argument that vegetables already contain toxins, which occur naturally to deter predators, and therefore we don’t need to be worried about small amounts of man-made pesticides. But I don’t understand: if plants, which we must eat to get our vitamins and phytonutrients, already contain toxins, then why add to the toxins they contain by eating vegetables with pesticides?

IS THERE A SAFE AMOUNT?

The basic question is whether there exists an amount of poison that is the minimum amount to cause any effect at all. Is there a threshold below which it doesn’t matter in any way that you swallowed a bit of poison?

As described above, levels of chemicals are additive (and sometimes worse than additive), and thus we really have no idea of the final effect of the mixtures we may be exposed to.

It also depends on the effect you are considering. If you worry about acute poisoning, meaning death within the week, there is definitely an amount that is safe. If you worry about getting leukemia and dying, there is an amount but it’s much lower. For example, mothers who use pesticides in their home up to a year before the birth of a child have children with a measurably higher risk of getting leukemia.

If you are trying to measure subtle changes in personality, or in intelligence, or behavior, then there often is an even lower limit of acceptable toxin. Over time, we have lowered the allowable limits of lead for example, because of being better able to measure the brain damage caused by small amounts of lead. First we used IQ, later we used reading scores.

You may say, what is the importance of this subtle behavior change? I may never notice the difference even with my kids. That may be true, but from the point of view of the country as a whole, if all the kids are a little more hyperactive, then thousands more kids will be actually “diagnosed” with ADHD, and thus many more will be taking medication and requiring follow up. It’s as though there were thousands of children on the cusp of being considered hyperactive, and this extra small amount of pesticide pushed them over the edge and into a “diagnosable” category. The same happens with developmental delay, or autism, or anxiety and depression. Many illnesses are a matter of degree.

BETTER DEFENSE

There is yet another concern. Some children have slower defenses than other kids when it comes to getting rid of these chemicals. A standard dose accumulates and will lead to symptoms they may never have had if they were a faster “detoxifier”. Doctors don’t test detoxifying capacity or efficiency. There is no way to know except after the fact, when neurological damage has occurred. In one recent case (the case of Heather Poling), the courts ruled that a young girl acquired autistic behaviors due to a vaccine she received, because she had a genetic defect that left her vulnerable to this. We wish we had ways to detect all such children ahead of time, but we don’t. We understand the pathways in only a small number of children. We see that many children with autism actually seem to regress like this girl, but we don’t understand the sequence of neurological events very well at all. So we can’t say what “caused” it, but chemicals known to be neurotoxins at a specific dose, while okay for most, may be very harmful for a few.

There is no doubt that disabilities, specifically learning and behavior disabilities in children, are on the rise. The chance of having a child with autism is about 1 in 50 at this time. Autoimmune diseases, asthma, eczema, and allergies are also on the rise, including severe food allergies. Even for adults, neurological diseases are on the rise, such as Parkinson’s disease, which has a proven link to pesticide use.

HOW DO WE DECIDE

In the face of neurological damage rising nationwide, would you choose to give your kids neurotoxins, in any amount? In the face of increasing immunological abnormalities, would you choose to give them immune system toxins? What if you have one of the children with the genetically slow detoxification pathways?

What is unfair in this country is that so few children have access to clean nutritious food, and that not all children are safe from harmful farm practices. Let’s right this! If all of us who can afford it insist on clean food, we will have more clean farms, and cheaper clean food. This will allow even more people to be able to afford clean, tasty, healthy food. This is how you correct an injustice.

Our main agricultural outputs include corn, soy, and wheat. The first two are controlled by a single corporation that happens to be a pesticide manufacturer, and whose publicly expressed goal is the control of the entire food supply. Massive government subsidies flow to this type of agriculture. In turn, the largest corporations fund our universities and direct the public conversation on the need for artificial inputs in order to grow affordable food.

Careful studies have shown, however, that we don’t need chemical agriculture. In fact, given climate change and yields under unpredictable weather conditions, small-scale organic agriculture is what we need to turn to in the decades to come.

This is the time to transition to organic food as a nation: for our health and that of our kids’, and our neighbors and their kids’; for our environment and for our future as a species on this planet.

Some Approaches Can Reverse Cognitive Decline

5 Comments

Read Now
 
Picture
In November 2014, California researcher Dale Bredesen reported on a therapeutic program he used to successfully reverse cognitive decline (see link at bottom of article). He reported on 10 patients who were enrolled in this program. Six of his 10 patients had discontinued work due to memory issues, but after following his program, they were able to return to work. All patients but one improved on objective measurements, as well as subjectively. Several months after the publication of this article, there are now about 45 patients and the results continue to be encouraging. A research study with 200 patients is being launched by MUSES Lab.
 
This therapeutic program is based on a multifaceted approach. It contains the following components:

o   The patients’ diet was optimized by minimizing carbohydrates and inflammatory foods

o   A 12 hour fast was instituted each night

o   Stress was reduced using a personalized approach

o   Sleep was optimized, including treating sleep apnea where needed

o   Exercise was increased

o   Brain stimulation was added in the form of software such as Posit

o   Blood tests were used to optimize B and D vitamin sufficiency, and zinc to copper ratio

o   Vitamin E, selenium, NAC, alpha-lipoic acid, coQ10 were added

o   Anti-inflammatory herbs were used for patients with high levels of inflammation

o   Thyroid hormone was balanced

o   Gastrointestinal function was improved

o   Herbs and other substances that improve cognition were recommended

o   Building blocks for brain cell communication were provided (Citicoline, DHA, etc…)

o   Heavy metals were tested and reduced where appropriate

This program is very exciting because there are no medications presently that are truly effective in preventing decline, let alone reversing it. It may seem strange that this hasn't made headlines: but what brand new medical therapy ever does?

First, there is Step 1: a small group of patients are convinced to try a new approach. If this works well, then, in Step 2, more patients are enrolled. Eventually, we get to Step 3: the drug company funds a large trial costing millions of dollars, researchers tally and publish the findings and gradually, the treatment is adopted by medical providers. The process normally takes about 15-20 years.

But here we are on Step 1. We have a group of patients who have met with resounding success. How do we get to Step 3: what deep pockets will fund this type of approach?

The treatment is time-consuming and demanding, but it does NOT pose a health risk. I see no reason not to consider it.

Most importantly, the program makes a lot of sense from a functional medicine perspective: we need to identify and correct all the underlying causes of inflammation, because inflammation disturbs mitochondria (energy transducers in your cells) and in turn that causes the brain to function very poorly. Then we need to use all the tools we have: we have research showing that exercise helps mitochondria a little bit; we know overnight fasting helps them a bit too; we know the supplements used in this program work a little bit; and we know a lot of people with Alzheimer's or Parkinson's or multiple sclerosis, or epilepsy, or depression and anxiety for that matter--benefit from the low-carb diet.

What Dr. Bredesen's approach does that is new is that it combines a large number of these interventions. He explains it thus: "If you had a roof with 17 holes in it, would you want just a single one fixed? Would that be satisfactory? So we fix all 17 holes, that is why there are so many components to this program."

I am very excited to put this to the test. I am sticking very close to Dr. Bredesen's successful recipe: first I do a functional medicine consultation, to uncover all the likely sources of inflammation and identify all the possible nutrient deficiencies. At baseline, we get brain function tests so we have a score to compare to in 3 months when we re-test.

Then, step by step, week by week, we add one or two components as tolerated. The visits can be brief, and follow up can be as frequent as you like. Within 3 months, with any luck at all, your life will be transformed.

If you wonder whether this is for you, you can use an online tool to see how your brain function compares to that of other people your age. You can take brain tests on Lumosity for example.

Vitamin D Supplementation is Often Beneficial

4 Comments

Read Now
 
Picture
Yet another study is reported today that casts doubt on the value of supplementing vitamin D. Subjects were given either 400 iu daily or 50,000 iu twice a week. No difference in outcome was seen. I am going to agree with them for one minute here: I would not use either one of these options.

However, it boggles the mind that we are still so unsophisticated in our analyses of vitamin D. I present here a summary of studies that DID find a benefit. Since randomized studies of supplementation have not found harm, it seems the choice is whether to take a risk (that appears very small so far) to get an advantage as detailed below.

MAIN TAKEAWAY POINTS:
  • Vitamin D supplementation is beneficial in a number of conditions and especially for patients below the 20 ng/mL cutoff
  • The dose of vitamin D is about 100 iu daily of vitamin D3 for each 1 ng/mL you want to increase the level by, double that for obese patient
  • Toxicity is unusual, but possible with doses above 10,000 iu daily
  • The ideal level to aim for may depend on the condition and the patient’s genetics; 50 ng/mL is reasonable, but levels up to 60-80 ng/mL or even 80-90 ng/mL have their supporters

For this review, I have focused on randomized controlled trials of vitamin D supplementation.

Vitamin D supplementation in general, without regard to condition or level, generally reduces all-cause mortality (Chowdhury et al, 2014) and improves pregnancy outcomes (Sablok, 2015).

The most obvious benefit of vitamin D supplementation is for people whose vitamin D is below 20 ng/mL. In my opinion, this group makes it worthwhile to screen everyone with a vitamin D level, as supplemented patients will experience fewer bone fractures, less injury from falls, better tooth retention, better sleep and well being, less overall pain, less cardiovascular disease, less asthma and COPD, less influenza, fewer colds, and less pneumonia (see Table 1).

If people already have certain medical conditions, raising vitamin D using supplements will help them to have better outcomes with Hepatitis C treatment, to have less joint pain (with rheumatoid arthritis), less neuropathy (with diabetes), less pain (with fibromyalgia), better glucose control (with gestational diabetes), lowered insulin resistance (teenagers with prediabetes), less eczema, and fewer episodes of otitis media (for children prone to otitis) (see Table 2).

One study compared gene expression in people with low vs. normal vitamin D levels. They found 66 genes expressing differently between the two groups. In vitamin D deficient subject, supplementation corrected the expression of these genes (Hossein-nezhad et al, 2014).

The expression of several immunological markers was improved in a group of patients with multiple sclerosis supplemented to a average level of 50 ng/mL (Terrier  et al, 2012).

In many cases, research has not shown a benefit to attaining levels above 35 ng/mL, and there are concerns that there may be adverse consequences of excessive vitamin D supplementation. However, it is hard to draw firm conclusions in that regard. Few research subjects attain levels much above 35 ng/mL, making it difficult to find statistically significant differences above that level. The studies showing associations between high vitamin D levels and certain illnesses do not involve a randomized controlled comparison of people taking different doses of vitamin D. This introduces the possibility that there are other reasons people with high vitamin D levels sometimes have higher fracture risk (Bleicher et al, 2014), more Type 1 diabetes (Gorham et al, 2012) or higher risk of cardiovascular disease.

For certain conditions, a vitamin D level above 40 ng/mL is the most beneficial (Munger et al, 2006). In fibromyalgia, maximum benefit was found when patients were supplemented to levels exceeding 48 ng/mL (Wepner et al, 2014). Some neurologists (Gominak et al, 2012) claim that it is necessary to supplement patients to levels of 60-80 ng/mL to correct sleep problems, including sleep apnea, and levels above 80 ng/mL may offer additional advantages in autism (Cannell, personal communication; Perlmutter—in his book, Grain Brain).

Some people have genetics that result in lower vitamin D levels (Wang et al, 2011). These variants are near genes involved in cholesterol synthesis, hydroxylation and vitamin D transport. There are also inborn errors of vitamin D metabolism, some of which can be overcome with vitamin D supplementation (Malloy et al, 2010).

Some people also have genetics that impair the hydroxylation of 25 OH vitamin D to the active form 1, 25 OH vitamin D. It is tempting to hypothesize that these are the patients who get more benefit from very high levels. Mitochondria are involved in this conversion, raising the possibility that mitochondrial dysfunction also impacts need for high levels of 25 OH vitamin D (See Perfect Health Diet website).

Vitamin D supplementation as a single 300,000 iu dose can also be used to treat primary dysmenorrhea (Lasco et al, 2012).

I would love to find research support for an ideal level being in the 50ng/mL, or the 70-80+ range. This is frequently recommended in functional medicine, but does not appear well supported, and certainly not by randomized controlled studies of supplementation.

Please comment if you have studies to support aiming for such a high level!

Why I am a germophile

8 Comments

Picture
The dictionary defines “germophobe” as “a person who fears physical contact with germs and is therefore obsessed with cleanliness”.

Given what we know now about the fact that there are 10 bacterial cells to each human cell in our bodies, this seems like strange behavior indeed. How can you even focus on the germs outside when there are so many germs inside? Yet, germophobes are very common. A recent entertaining blog contrasted “germophile” and “germophobe”, insisting that one was not better than the other.

But should we choose consciously? Is one better than the other? What would “better” mean in this case? Of course from my point of view as a functional medicine physician, “better” means free of illness, and full of vitality and a sense of well-being.

If that is the goal, I think “germophile” wins.

WE SPREAD GERMS INSTINCTIVELY
The thing that I find most relevant to thinking about this question, is how many of our automatic and most treasured behaviors involve maximizing the transfer and spreading of germs. From the first moment of life, which, if we are lucky, involves a short trip down the birth canal, it’s all about getting as many germs as we possibly can. Breast milk is full not only of germs, but of germ “landing docks”, that allow germs to take residence in the baby’s intestine. Breast milk is also full of certain substances the baby cannot digest. They are solely for feeding the bugs that begin to inhabit the baby—letting them go hungry would be a disaster!

Of course that is just the start. For some reason, I was overwhelmingly driven to kiss my babies over and over again. I touched them a lot and I have to say, I didn’t bathe them daily because they just didn’t seem dirty to me.

Many of our other behaviors (kissing in general, shaking hands, touching, hugging) also seem aimed at sampling the environment and each other, and becoming maximally colonized with germs. Babies are notorious at mouthing everything within their reach. Is this really because the mouth is another “sense organ” to them, or is it because they are busily and systematically putting together an extensive germ collection? Read just a bit of the latest science on the gut-brain connection and you will learn that gut bacteria impact brain development and our responses to stress later in life. Even certain parasites are favorable to the brain. I am becoming a bigger and bigger fan of germs. To be honest, I am in awe of what they do for us.

WE RELY ON BACTERIA
DNA in the human cell comprises about 20,000 genes. Each gene is the blueprint for a protein that will then carry out a function within the cell or in another part of the body. However, the human organism requires about 500,000 to a million different proteins to function. Where do they come from? Some have hypothesized that the 20,000 human genes mix and match and combine bits of each other to become half a million different proteins. Others have argued that this is not the case: we get the vast majority of our cellular-level tools from bacteria.

Each bacteria only has a few thousand genes. So the goal, clearly, is to collect as many different bacterial strains as possible as quickly as you can. Babies are especially well-suited for this. They have a “weak” immune system, so as not to kill off germs right away: the germs get the benefit of the doubt. As we get older, we still have a compulsion (or brilliant adaptation) to keep sampling: we touch things, then touch our face or somehow put fingers in the mouth. There could be a way that this helps us cope with what our environment requires of us: detoxification, absorption or manufacture of vitamins, immune system training and performance, connection with other human beings. We know bacteria influence or perform these functions. There could be more: we could be adapting to different threats: savanna vs. forest, tide pools vs. mountaintops. I’m deeply intrigued.

And in turn, we impact our environment bacteriologically in exquisitely specific ways: each finger has its specific bacterial signature. What purpose does that serve?

GUT BIOME DIVERSITY
Now that we are measuring the gut biome (collection of all bacterial DNA within a human being), we know that within the body, about 99 genes are of bacterial origin for each 1 human gene. This is due to the large variety of bacteria we possess. The diversity of bacterial species within the gut is reported as a measure of robust gut health.

When we observe indigenous cultures, we find that they do outrageously “germy” things, like let a carcass fester in the sun before consuming certain animals. All traditional cultures have a typical fermented food. Some will only consume certain foods if they have been fermented. We also notice that their rates of allergies, asthma, autoimmune disease, obesity, diabetes and most cancers are or were lower than ours. We think this is all related to gut biome diversity.

Our laboratory animals may also be too sterile and may not represent how life really means to proceed. Rat cages are routinely sterilized, and their food, if you think about it, is typically entirely processed. Perhaps they represent what it would be like for us if we lived like that.

GUT AND PSYCHOLOGY
The most exciting findings recently are in psychobacteriology (I made that up, I don’t think they have a name yet). Most of our nervous system is in the gut. Most of our immune system is there too. It is where the action is, clearly. Bacteria make substances that are recognized by our nervous system. Researchers have found that bacteria in the gut communicate with our brains using the vagus nerve, that links the intestinal area with the brain. They help us be calm, resourceful and connect better with others. They may control appetite and food choices. In turn, all of the above influences our immune system function.

I’m starting to think that germs make us better people—healthier, more connected with each other, more adaptable, and more relaxed. I think the vast majority of bacteria are helpful, and we should re-examine each one of our assumptions about killing them. There is a minimum of sanitation that prevents important infectious illnesses but by and large, we have gone overboard. So I am a germophile.

Why there is controversy about gluten

VIDEO VERSION here:
Picture

What is your opinion about gluten? How have you come to your conclusions? As a functional medicine physician, I find most articles I read in the popular press incomplete. I would like to share what I have learned in my journey from conventional doctor to functional medicine physician.

The basic statistic is this: 1% of Americans have celiac disease, a well-established autoimmune disease. An additional 5-6% of Americans may have non-celiac gluten sensitivity (NCGS), which has very recently been recognized as a real illness by gastroenterologists. Both celiac disease and NCGS can have symptoms that have nothing to do with the gut.

So, why are 10-30% of Americans (depending on the survey) trying to reduce the gluten in their diets? Are most of them fools?

A new disease

First let me point out that until 2011, most gastroenterologists refused to believe that gluten could cause stomach cramps in patients without celiac disease. That is barely 4 years ago. Now many admit that they were missing a lot of people with NCGS. Could they be missing something else? What will they admit to in another 4 years? Would you prefer to get healthier now, or would you like to wait?

I understand the strong drive to prevent our patients from falling prey to expensive scams. I understand our hesitation to recommend a diet that has not been “proven” safe. I also understand that we worry that patients will neglect some other treatable condition and instead do diet experiments we believe are doomed to fail. So I think physicians who don’t believe so many people should be gluten-free have good intentions.

I also know that American agriculture has a strong vested interest in maintaining (increasing, really) our collective consumption of wheat products. And American processed food manufacturing and food retailing has a similar strong vested interest. In the setting of powerful conflicts of interest, mainstream media does not serve us well.

Here is my point of view

As a doctor, I see sick people. I don’t see well people because they don’t seek me out. Out of the sick people I see, many have a problem with gluten. As a quick review, gluten is a protein found in wheat, barley, rye and in contaminated oats. It contains another protein called gliadin, which seems to be the one to cause problems.

Types of problems with gluten

Here’s some of the problems my patients are having, in order of increasing difficulty to diagnose:

o   Some people have wheat allergies. When they eat wheat, they get a stuffy nose, or they break out in hives. This is diagnosed with a simple blood test for Wheat IgE.

o   Many people have a problem with processing carbohydrates (40% or more, actually). This may show up in the blood as a high Hemoglobin A1C (over 5.6%). People with this problem can easily demonstrate to themselves, by using an inexpensive glucometer (freely available on Amazon) that a meal consisting of cereal, or sandwich, or pasta, results in elevated blood sugar (as opposed to a salad, or a meal consisting of only lean protein plus broccoli).

o   Some people have celiac disease. They have the genetics that put them at risk (positive DQ2 or DQ8 genes) and in addition, they have a positive transglutaminase (tTg) IgA antibody, endomysial antibody or deamidated gliadin antibody. Note that testing only for the tTg is not enough to rule out celiac disease. In addition to blood testing, gastroenterologists recommend an intestinal biopsy to officially call it celiac disease, but some argue that positive antibodies are sufficient to recommend a gluten-free diet.

o   Some patients have a problem tolerating lectins, which are also in beans and some other foods. A possible test for lectin sensitivity is the wheat germ agglutinin antibody test.

o   Some people have a problem with FODMAPs. These are components (fermentable carbohydrates) abundant in certain foods (including wheat) that cause bloating in susceptible individuals. There is a hydrogen breath test that may or may not help with detecting this.

o   Some people react to breakdown products of gluten and dairy called gluteomophins and casomorphins. I am not sure these can be measured outside of research labs.

o   Some people have non-celiac gluten sensitivity (NCGS). At this time, this is a condition without clear diagnostic criteria. If you say that you feel better off wheat, that makes you a candidate. There are tests for anti-gliadin antibodies, but they are not universally accepted by conventional medicine. There are also biopsy findings but most people with gluten sensitivity do not undergo intestinal biopsies.

The test I use is from Cyrex Laboratories. It finds more people with anti-gliadin antibodies than any other test.

You will see the figure of 3-5% of people having NCGS. This is when you test all the patients in a gastroenterology practice. If you take people with joint pains, or people with balance problems, or people with autoimmune disease, or people in my practice, you will find a different percentage--sometimes lower, sometimes much higher.

Why do I take patients off gluten?

Taking people off gluten is one of my most common initial dietary changes. Here’s why I do it, and why this makes all the articles you read by science journalists who have consulted with conventional medical sources incomplete.

I take anyone off gluten who has significant inflammation. How do I know they have inflammation? I learned that from reading research studies about the medical conditions I treat. Most people who haven’t felt well for months or years (my specialty is chronic illness) have inflammation. In any given person with a health complaint, I actually have to prove it’s not a factor. It is my job to improve this aspect of the immune system in all my patients. It’s the only way I can hope to reverse illness without the use of drugs.

Why is gluten a problem for inflammation?

First, gluten causes increased intestinal permeability in everyone temporarily. For some, this is repaired before the next dose of gluten. For others, it’s not. Leaky gut will cause leakage of large poorly digested proteins from the gut into the bloodstream, and basic immunology tells us that these tend to elicit an immune response (i.e. inflammation). In addition to this, some people are exquisitely sensitive to some undigested proteins from specific foods. Leaky gut also allows gut bacteria to leak into the bloodstream, and these bacteria have a substance on them called lipopolysaccharide (LPS), which is also a strong immune system stimulant (i.e. inflammatory).

It has been hypothesized that a healthy gut microbiome may minimize the issues with intestinal permeability. However, as we well know, our microbiomes have been weakened by our environment and our customs (such as hygiene and antibiotics).

Second, wheat products tend to take the place of healthier products in our diet. They present a number of drawbacks, including the fact that they have a high glycemic index, and the fact that they don’t have as many vitamins and phytonutrients as do fruits, vegetables, seeds and nuts. If you replace your cereal/bread/pasta with a “gluten-free” version, you will not see much of a difference in your nutrient intake. However, this is not what I recommend. Gluten-free products are processed foods, and thus of little use to any person who is trying to overcome a serious medical problem. If you replace your breakfast cereal with a smoothie full of fresh produce, your lunchtime sandwich with a big colorful salad, and your evening noodles or pizza with healthy protein and a vegetable stir-fry—then you will indeed reap the rewards of a healthier diet.

Third, changing your diet changes your beneficial bacteria. As they are in charge of your immune system, of making vitamins for you, of breaking down toxins or causing inflammation, changing them is often beneficial in changing your symptoms.

Traditional vs. updated

The controversy about gluten relates to the different ways in which patients with chronic illness are viewed in the conventional vs. the alternative medicine model. In the conventional model, we seek a single cause—an infectious agent, an injury, a genetic predisposition. In the alternative model (or more precisely in this case, the functional medicine model), the “terrain” or underlying weakness of the individual is the most important factor: the microbiome modulates genetics to create inflammation that results in disease.

Gluten acts almost like a litmus test that reveals significant inflammation and gut microbiome weakness. These preconditions exist before gluten is added but worsen with the addition of gluten. Thus, many people find that they feel better when they transition from a standard diet to a high nutrient, gluten-free diet.

The controversy about gluten might simply be related to our shifting understanding of the underlying drivers of health and disease.

WHAT IS ROOT-CAUSE RESOLUTION MEDICINE?

49 Comments

In functional medicine, we talk a lot about the term “root-cause resolution”. What does it mean though? How do you know that you are tackling the root cause of your illness?

When I go online to see what people are saying about functional medicine, I see that they seem confused by the term “root cause”.

They say that all medicine is oriented to finding the cause of your concerns and resolving it. For example if you go in to see a doctor and you complain of urinary discomfort, they will look for an infection, or some other cause, and treat you accordingly.

Are they right? Is all medicine “root cause” medicine?

Well it depends if your illness is acute (has lasted only a short time) or chronic.

If your illness is chronic, such as a rising blood pressure that has now exceeded the threshold for “abnormal”, your doctor will check a blood test, recommend you eat less salt, and put you on a medication. That is because conventional medicine considers that hypertension is most often “idiopathic”.

Picture
IDIOPATHIC
Idiopathic is a Greek word meaning “sickens itself”, from (idio-, self, and –pathic, illness). Hypertension sickens itself. That is absurd, of course. So in medical school I refused to use that word, and substituted another Greek word, “cryptogenic”, which means that the origin (-genic) is hidden (crypto-).

To practice root cause medicine you begin by believing that there’s a good chance you can find the hidden origins of diseases that conventional medicine believes are “cryptogenic.” The reason root-cause medicine is so valuable is that if you can find the root cause, you stand a better chance to reverse the illness (not just manage it).

So if a patient comes in with joint pains, and he or she gets ibuprofen, or curcumin, if that is all that gets done, this is not “root cause” medicine. The patient didn’t have a curcumin deficiency. The patient will be more comfortable on curcumin, but if you are practicing functional medicine, you will not stop there.

LOOK FOR A CAUSE
You will target inflammation and there are many ways to do that. You will take a full history, to see how this pain came about, and that will give you a clue as to whether you should try first to change the diet, teach stress reduction, recommend rest or exercise, or target something more obscure like coenzyme Q10, leaky gut, thyroid problems, insulin issues, heavy metals, and so on.

Once you find, say, leaky gut, you still have not found the root cause. Why does he have leaky gut? This could be a variety of things from diet to stress, to poor probiotics.

And if it’s stress, what is the root cause of that? You have to consider your patient’s early life history, and investigate perhaps trauma work or therapy.

So, how do you know when to stop looking for underlying causes? How do you know you are dealing with a root cause? I’ve made up an acronym to remind me of the main root causes that may not have deeper underlying causes: G-FLAT

Picture
G stands for Genetics, and Germs.

FLAT are events, or external inputs: Food, Life events, Actions and Toxins

“Genetics” may include for example MTHFR: by giving people with a slow variant of the MTHFR gene a surplus of folate (sometimes through food, sometimes with supplements) we compensate for a genetic problem.

We only have a few genes we know how to bypass, but we can help the body modify the expression of hundreds of genes by targeting inflammation genes with lifestyle or nutraceuticals (even better, according to recent research, with both).

“Germs” refers to causes like Lyme disease and chronic viruses that can be participants in patients’ chronic conditions.

External inputs are the most common issues. They include the following:
-       “food” includes inflammatory food, like too many grains, meat, or salt
-       “life events” includes trauma, either psychological or physical
-       “actions” includes lack of sleep, repetitive motion, lack of exercise
-       “toxins” include processed foods, and environmental toxins

Of course, illness arises from the interaction of these factors, but first we have to strip the situation down to these essential elements, and then devise a plan of action.

It may take many steps to uncover the root cause, and you really want a motivated patient and a patient and persistent provider.

So make sure you go all the way to G-FLAT!
