A general term for indigestible complex carbohydrates—bran and cellulose—of plant origin that form the bulk of the stool. Roughage absorbs water, is laxative, and binds bile acids and metabolites; increased dietary roughage is linked to a decreased incidence of diverticulosis and colorectal cancer, and reduced serum cholesterol.
