High Fiber and Fermented Foods May Benefit Microbiome

The foods we eat can impact our gut microbiome, which in turn can impact a number of health functions, including immune response and inflammation. In a small study of people randomized to either a high-fiber diet or a high-fermented-foods diet, fermented foods were found to improve the diversity of the microbiome and decrease inflammation, while high-fiber foods were found to impact the microbiome and trigger a personalized immune response.
