Fiber First: Whole-Plant Foods Beat Supplements for Gut Health
Gastroenterologists say most people should boost fiber mainly through a variety of fiber-rich plant foods (fruits, vegetables, whole grains, beans, nuts, seeds) to support the gut microbiome and reduce chronic-disease risk, with daily targets of 25 g for women and 38 g for men, though many Americans average about 15 g. Supplements like psyllium can help when diet alone falls short, but they provide a single type of fiber and don’t offer the wide range of nutrients found in whole foods.
