Eating only wild foods reshapes your gut microbiome in just weeks, study shows

A new study shows that an eight-week wild-food-only diet in a modern adult leads to dramatic, partially lasting changes in the gut microbiome’s composition and function. While no “ancestral” microbes reappeared, the shift increased fiber-degrading species and reduced dairy-associated bacteria, highlighting the powerful role of diet.
