Fruits and Vegetables Improve Gut Bacteria

A diet rich in fruits, vegetables, and other high-fiber, plant-based foods improves gut bacteria diversity within two weeks, according to research published in Nutrients. Researchers assessed gut bacteria composition in 248 participants over a two-week dietary intervention that increased fiber intake. Those who consumed more fruits, vegetables, and grains improved gut bacterial diversity when compared to participants who did not change their diet. High-fiber diets increase bacteria associated with anti-inflammatory compounds linked to improved glucose tolerance and metabolism.
