Dietary fiber is the part of plant foods that the body cannot digest. Eating foods with fiber helps to keep the digestive tract healthy and stabilize blood sugar levels.
Fiber in the diet is classified as either soluble or insoluble.
Soluble fiber has been shown to help lower blood cholesterol. Foods high in soluble fiber include oat bran, oatmeal, dry beans and peas, rice bran, barley, citrus fruits, strawberries, and apple pulp (the solids left after making apple juice).
Insoluble fiber does not lower blood cholesterol, but it is important in keeping the bowels healthy and preventing constipation and diverticular disease. Foods high in insoluble fiber include whole wheat breads, whole-grain cereals, and wheat bran. Other examples are cabbage, beets, carrots, brussels sprouts, turnips, cauliflower, and apple skin.
