definition of dietary fiber: dietary fiber is a variety of plant substances that are not starch polysaccharides, mainly from the cell walls of animals and plants, including cellulose, lignin, wax, chitin, pectin, β-glucan, inulin and oligosaccharides, etc. It is usually divided into two categories: water-insoluble dietary fiber and water-soluble dietary fiber.

Health value: The cellulose in human diet is mainly contained in vegetables and coarse cereals. Although it can't be digested and absorbed, it can promote intestinal peristalsis and facilitate the excretion of feces. Herbivores rely on the microbes in their digestive tract to decompose cellulose, so that it can be absorbed and utilized. Dietary cellulose includes crude fiber, semi-crude fiber and lignin. Dietary cellulose is a kind of substance that cannot be digested and absorbed. It used to be considered as "waste", but now it is considered to play an important role in safeguarding human health and prolonging life.

Hazard of dietary fiber: Supplementing a large amount of fiber may lead to hypoglycemia. Supplementing a large amount of fiber may reduce the digestion and absorption rate of protein. Supplementing a large amount of fiber may affect the absorption of elements such as calcium, iron and zinc. A large number of fiber supplements may make the gastrointestinal tract of diabetic patients "overwhelmed".
