Green bananas

The b anti-diarrheal effect of green bananas is due to them containing a particular type of fiber known as resistant starch.

Humans cannot digest resistant starch, so it passes through the digestive tract to the colon, the last part of the intestine.

In the colon, it is slowly fermented by intestinal bacteria to form short-chain fatty acids, which stimulate the intestines to absorb more water and strengthen stools.

Pectin supplementation

Humans do not digest pectin and it remains in the intestinal tract where it effectively strengthens stools and prevents diarrhea.

One study showed that 82% of children who took pectin supplements daily recovered from diarrhea within 4 days.
