Soluble fiber gives stool bulk. Foods that are good sources of soluble fiber include apples, bananas, barley, oats, and beans. Insoluble fiber helps speed up the transit of food in the digestive tract and helps prevent constipation.
Soluble fiber, such as beta-glucan and glucomannan, mixes with water to form a viscous, gel-like substance that slows down how fast the stomach releases digested food into the gut ( 4 ). Eating more soluble fiber can also help you lose belly fat and prevent belly fat gain.
