INSIGHT

Microbiome Underlies Many Chronic Diseases

Modern chronic diseases often have a major microbiome component beyond obvious GI symptoms.
William Davis estimates the microbiome plays a role in most chronic illnesses including dementia, heart disease, and mood disorders.

ADVICE

Minimize Microbiome-Damaging Exposures

Reduce exposures that damage the microbiome like unnecessary antibiotics and glyphosate.
Favor real food, organic when possible, and minimize household and dietary chemical exposures.

INSIGHT

Small Bowel Overgrowth Drives Endotoxemia

Small intestinal overgrowth (SIBO) is more common than assumed and drives systemic inflammation via endotoxemia.
Fecal microbes ascending into the small bowel inflame the gut and release toxins into the bloodstream causing distant symptoms.
