Description
Wheat fiber is predominantly found in whole-grain wheat and offers notable nutritional benefits, mainly through its role as insoluble dietary fiber, aiding digestion and supporting gut health���. Whole wheat contains approximately 10.7–15 grams of fiber per 100 grams, with fiber accounting for 12–15% of the dry weight���.Types of Wheat FiberThe majority of wheat fiber is insoluble, mainly present as arabinoxylan (about 70%) and cellulose, with small amounts of soluble fibers (fructans)��.Insoluble fiber passes through the digestive tract largely unchanged, bulking stool and promoting regular bowel movements, while a portion can act as prebiotics and feed beneficial gut bacteria���.Nutritional ProfileFor 100 grams of whole-grain wheat flour: about 10.7–14.6 grams of dietary fiber, 13.2 grams of protein, 72 grams of carbohydrates, and 2.5 grams of fat��.Most of the fiber is lost if the flour is refined and the bran removed�.Health BenefitsWheat fiber may lower the risk of colon cancer, type 2 diabetes, and stroke by improving gut health, slowing glucose absorption, and offering antioxidative effects��.Magnesium and other micronutrients in whole wheat assist in carbohydrate metabolism and insulin sensitivity�
