The Gut Microbiome Key Talking Points
1. Why Gut Health Matters
• The gut microbiome is home to trillions of microorganisms
critical to health.
• These microbes regulate digestion, immunity, mood, and
even influence the brain.
• A disrupted microbiome is linked to obesity, autoimmune
conditions, anxiety, depression, and more.

2. How We Lost Our Healthy Microbiome
• Processed foods, sugar, glyphosate, and artificial additives
destroy beneficial bacteria.
• Antibiotic overuse wipes out both harmful and helpful
microbes.
• Modern grains introduce compounds like gliadin and
amylopectin A, which promote inflammation and blood sugar
spikes.

3. The Super Gut Protocol (Dr. William Davis)
A 3-step process to restore the microbiome:
• Eliminate Offenders: Cut out sugar, wheat, processed
foods, and reduce antibiotics.
• Reintroduce Missing Microbes: Add fermented foods
(kefir, yogurt, kimchi, sauerkraut) and specific probiotic
strains.
• Feed Your Microbes: Eat prebiotic-rich foods like onions, garlic, leeks, asparagus, and green bananas.

Benefits of a Rebuilt Microbiome
• Better digestion and regularity
• Clearer skin
• Deeper sleep and higher energy
• Reduced anxiety and improved mood
• Strengthened immune system
• Weight loss and improved metabolic health

Spotlight on Probiotic Strains
Key microbes recommended in the Super Gut protocol:
1. Lactobacillus reuteri
• Boosts oxytocin, improves skin, enhances muscle
strength
• Found in homemade fermented dairy

2. Bifidobacterium infantis
• Reduces bloating and supports the gut lining
• Found in breast milk and supplements

3. Bifidobacterium longum
• Supports brain health and mood balance
• Available in fermented dairy and supplements

4. Lactobacillus gasseri
• Helps reduce belly fat, improve metabolic health

How to Reintroduce These Probiotics
• Make your own fermented yogurt using targeted probiotic
strains (e.g., L. reuteri)
• Use high-fat dairy or non-dairy bases for fermentation at
home
• Choose potent probiotic supplements if homemade options
aren’t feasible
