5 surprising facts about gut health he wants you to know
The most important food for the gut microbiome is fiber from a variety of whole plant foods, including fruits, vegetables, whole grains, legumes, and nuts. Gut microbes digest fiber and produce beneficial metabolites, such as short-chain fatty acids, that nourish the intestinal barrier, improve immune function, and help prevent inflammation.
Unfortunately, at least 95% of Americans do not meet the Recommended Daily Allowance (RDA) of dietary fiber (38 grams for men and 25 grams for women). Meanwhile, optimizing gut health means going beyond the RDA. The more fiber you eat, the more you can cultivate beneficial fiber-digesting gut bacteria and improve the overall diversity of species that make up your gut microbiome. A diverse gut microbiome is an important marker of gut health.
