Fiber Fueled

1. The gut microbiome is the engine driving human health

You are only 10 percent human—and 90 percent bacteria!

Microbial diversity is crucial. The human gut contains 39 trillion microorganisms, including bacteria, yeasts, parasites, viruses, and archaea. This diverse ecosystem plays a vital role in various aspects of human health, including:

• Immunity: 70% of the immune system resides in the gut
• Metabolism: Gut microbes influence weight, insulin sensitivity, and nutrient absorption
• Hormonal balance: Microbes affect estrogen, testosterone, and other hormones
• Cognition: The gut-brain axis influences mood, memory, and neurological health
• Gene expression: Microbes can turn genes on or off through epigenetic mechanisms

Dysbiosis leads to disease. When the gut microbiome loses diversity and balance, it can result in increased intestinal permeability ("leaky gut") and the release of bacterial endotoxins. This has been linked to numerous health issues, including:

• Autoimmune disorders
• Obesity and metabolic syndrome
• Cardiovascular disease
• Neurological conditions like Alzheimer's and Parkinson's
• Mental health disorders like anxiety and depression

2. Modern lifestyle has led to overfed, undernourished, and overmedicated population

We are fatter, sicker, and more heavily medicated than at any other time in human history.

The Standard American Diet (SAD) is problematic. The modern diet is characterized by:

• High consumption of processed foods, meat, and dairy
• Low intake of whole plant foods
• Excessive sugar, salt, and unhealthy fats
• Numerous chemical additives and preservatives

This dietary pattern, combined with other lifestyle factors, has resulted in:

• 72% of Americans being overweight or obese
• 60% of adults using prescription drugs
• Declining life expectancy for the first time in over 100 years

Overreliance on medication. The pharmaceutical industry has significantly influenced healthcare, leading to:

• 269 million antibiotic prescriptions per year
• 115 million proton pump inhibitor prescriptions
• 30 billion doses of nonsteroidal anti-inflammatory drugs (NSAIDs)

These medications, while sometimes necessary, can disrupt the gut microbiome and contribute to long-term health issues.

3. Fiber is the key to unlocking gut health and overall well-being

97 percent of Americans are not receiving the minimal daily recommended amount of fiber, let alone what I would characterize as optimal.

Fiber fuels beneficial gut bacteria. Dietary fiber, found exclusively in plant foods, serves as a prebiotic that nourishes beneficial gut bacteria. When these bacteria ferment fiber, they produce short-chain fatty acids (SCFAs), which have numerous health benefits:

• Reduce inflammation
• Strengthen the gut barrier
• Regulate appetite and metabolism
• Support immune function
• Protect against cancer and cardiovascular disease

Diverse fiber sources are crucial. Different types of fiber feed different bacterial species, so consuming a variety of plant foods is essential for maintaining a diverse and healthy gut microbiome.

• Aim for at least 30 different plant foods per week
• Include a mix of fruits, vegetables, whole grains, legumes, nuts, and seeds
• Gradually increase fiber intake to avoid digestive discomfort

4. Diversity of plants is the foundation of a healthy diet

The single greatest predictor of a healthy gut microbiome is the diversity of plants in one's diet.

Plant diversity supports microbial diversity. Eating a wide variety of plant foods provides:

• Different types of fiber to nourish various gut bacteria
• A broad spectrum of phytochemicals with unique health benefits
• Essential vitamins, minerals, and antioxidants

Aim for 30+ plant foods per week. This can include:

• Fruits and vegetables of different colors
• Whole grains (e.g., quinoa, oats, brown rice)
• Legumes (e.g., beans, lentils, chickpeas)
• Nuts and seeds
• Herbs and spices

Embrace whole plant foods. Focus on minimally processed plant foods rather than refined or processed versions. Whole foods retain their natural fiber and nutrient content, providing maximum benefits for gut health and overall well-being.

5. Food sensitivities can be overcome through gradual reintroduction

When we damage the gut and reduce diversity, we also reduce the number and types of digestive enzymes in our gut.

Food sensitivities often stem from gut damage. Many people who experience digestive discomfort from certain foods (e.g., beans, broccoli, gluten-containing grains) have underlying gut issues rather than true allergies or intolerances.

The gut can be retrained. By gradually reintroducing problematic foods and increasing overall plant diversity, most people can overcome food sensitivities:

1. Start with small amounts of challenging foods
2. Slowly increase portion sizes over time
3. Pay attention to individual tolerance levels
4. Focus on overall gut health through fiber-rich foods and stress reduction

FODMAPs and food sensitivities. FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols) are types of carbohydrates that can cause digestive issues in some people. Understanding FODMAP content in foods can help guide reintroduction efforts.

6. Fermented foods supercharge gut health and plant diversity

Every single culture in human history has fermented foods as a celebrated part of their food tradition.

Fermentation enhances nutritional value. The fermentation process:

• Increases bioavailability of nutrients
• Creates beneficial bacteria and yeasts
• Produces unique compounds like exopolysaccharides
• Reduces anti-nutrient content (e.g., phytic acid, lectins)

Diverse fermented foods offer unique benefits:

• Sauerkraut: Rich in probiotics and cancer-fighting compounds
• Kimchi: Supports weight loss and improves insulin sensitivity
• Miso: Protects against cancer and promotes bone health
• Tempeh: High in protein and beneficial isoflavones
• Kombucha: Contains beneficial acids and antioxidants

Incorporate fermented foods gradually. Start with small amounts and increase slowly to allow your gut to adapt. Aim for a variety of fermented foods to maximize benefits.

7. Prebiotics, probiotics, and postbiotics work synergistically for optimal health

Prebiotics + Probiotics = Postbiotics

Prebiotics fuel beneficial bacteria. These non-digestible fibers and compounds serve as food for probiotic bacteria in the gut. Sources include:

• Soluble fiber from fruits, vegetables, and whole grains
• Resistant starch from cooled potatoes and legumes
• Polyphenols from berries, tea, and cocoa

Probiotics introduce beneficial bacteria. While probiotic supplements can be helpful, fermented foods are often a better source of diverse, naturally-occurring probiotics.

Postbiotics provide health benefits. These are the beneficial compounds produced when probiotics ferment prebiotics, including:

• Short-chain fatty acids (SCFAs) like butyrate, acetate, and propionate
• Vitamins B and K
• Antimicrobial peptides

The synergistic relationship between pre-, pro-, and postbiotics highlights the importance of a diverse, plant-rich diet combined with fermented foods for optimal gut and overall health.

8. F.G.O.A.L.S: A framework for incorporating gut-healing foods

F GOALS plants are thin-skinned foods. There's no rind or skin to peel away, with the exception of onions and garlic. So any chemical that's sprayed on it is a part of it, and you can't guarantee that you can wash it off.

F.G.O.A.L.S. represents key food categories:

• F: Fruit & Fermented foods
• G: Greens & Grains
• O: Omega-3 Super Seeds
• A: Aromatics (onions, garlic)
• L: Legumes
• S: Sulforaphane (broccoli sprouts and other cruciferous veggies)

Incorporate these foods regularly. Each category offers unique benefits:

• Fruits: Rich in fiber, antioxidants, and phytochemicals
• Fermented foods: Provide probiotics and enhanced nutrients
• Greens: Highly nutrient-dense and low in calories
• Whole grains: Offer prebiotic fiber and essential minerals
• Omega-3 seeds: Support heart and brain health
• Aromatics: Contain powerful anti-inflammatory compounds
• Legumes: High in fiber and plant-based protein
• Cruciferous vegetables: Rich in cancer-fighting sulforaphane

Choose organic when possible. These foods are more likely to absorb pesticides and other chemicals, so opting for organic versions can reduce exposure to harmful substances.

9. Healthy habits and lifestyle choices complement dietary changes

Health during our lifetime is the sum of all of the small choices we make minute by minute, day by day.

Develop a health mindset. Focus on progress over perfection, celebrating small improvements and viewing challenges as opportunities for growth.

Incorporate key lifestyle elements:

• Hydration: Start the day with water and stay hydrated throughout
• Sleep: Prioritize 7-9 hours of quality sleep per night
• Exercise: Engage in regular physical activity, including post-meal walks
• Stress management: Practice mindfulness, meditation, or other relaxation techniques
• Social connection: Nurture relationships and spend time with loved ones
• Time in nature: Regularly expose yourself to outdoor environments

Practice mindful eating. Pay attention to your food, eat slowly, and listen to your body's hunger and fullness cues. This can improve digestion and prevent overeating.
