The EatoBiotics food library — every food examined for its microbiome impact. What it does, why it matters, how to eat it, and what the science says. One food at a time. Growing every week.

Foods that feed and nourish your beneficial gut bacteria.
Probiotic Foods
Fermented foods that add live cultures to your microbiome.
Postbiotic Foods
Foods whose compounds directly repair the gut lining and reduce inflammation.
