Also known as roughage, dietary fiber can help reduce the risk of heart disease. Both soluble and insoluble dietary fiber should be included in your total intake. Good sources of soluble fiber are oat bran, barley, beans, peas, apples, and citrus fruits. Fatty acids that are absorbed into the bloodstream and appear to play a role in lowering cholesterol levels are formed when soluble fiber breaks down in the digestive tract. Good sources of insoluble fiber are wheat bran, whole grains, vegetables, and fruits.
Insoluble fiber helps prevent and control intestinal problems.
