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 miscellaneous grains. Although it cannot be digested and absorbed, it can promote intestinal peristalsis and facilitate fecal excretion.
