May support digestive health

The fiber in the diet has been linked to a variety of health benefits, including improved digestion. One medium banana contains about 3 grams of fiber. Prebiotic fiber is resistant starch, which is found in unripe bananas. Prebiotics bypass digestion and end up in your large intestine, where they feed the good bacteria in your gut.

Furthermore, pectin, a fiber found in both ripe and unripe bananas, may aid in constipation prevention and stool softening. Some in vitro studies even suggest that pectin may help protect against colon cancer, though human studies are needed to confirm this benefit.
