Dietary fiber refers to food nutrients that are difficult to digest and have the function of absorbing water in the digestive system. Dietary fiber is mainly a variety of non-starch polysaccharide plant substances, including cellulose, lignin, chitin, pectin, β-glucan, inulin and oligosaccharides, which are usually divided into two categories: water-insoluble dietary fiber and water-soluble dietary fiber. It is an indispensable substance for a healthy diet. Fiber can clean the digestive wall and enhance the digestive function. At the same time, fiber can dilute and accelerate the removal of carcinogens and toxic substances in food, protect the fragile digestive tract and prevent colon cancer.
