Dietary Fiber and Health

JAMA. 1989;262(4):542-546. doi:10.1001/jama.1989.03430040114037

During the last 18 years, considerable research has been conducted on the role of dietary fiber in health and disease. Interest was stimulated by epidemiologic studies that associated a low intake of dietary fiber with the incidence of colon cancer, heart disease, diabetes, and other diseases and disorders. Dietary fiber is not a single substance. There are significant differences in the physiological effects of the various components of dietary fiber. A Recommended Dietary Allowance for dietary fiber has not been established. However, an adequate amount of dietary fiber can be obtained by choosing several servings daily from a variety of fiber-rich foods such as whole-grain breads and cereals, fruits, vegetables, legumes, and nuts.
