Glossary Term:


fiber, dietary



includes a wide variety of plant carbohydrates that are not digested by humans. Fibers are grouped as soluble (like oat bran) and insoluble (like wheat bran). Beans, vegetables, whole grains, and fruits are good sources of fiber. Links between fiber intake alone and risk of cancer are not proven, but eating these foods is still recommended because they contain other substances that may help prevent cancer. They also have other health benefits.
