The edible fiber is 'the plant compound can not be decomposed by human digestive enzyme generally', so the fiber is not absorbed by human body and is discharged out of the body under normal conditions, and the function of the edible fiber is very large. The edible fiber comprises cellulose, pectin, oligosaccharide, lignin, colloid and the like which exist in foods such as fruits, vegetables, grains and the like, and has important effect on human health.

The cellulose in human diet is mainly contained in vegetables and crude cereals, and although it cannot be digested and absorbed, it has the functions of promoting intestinal tract movement and facilitating feces discharge. The herbivore relies on the symbiotic microorganisms in the digestive tract to decompose cellulose, so that the cellulose can be absorbed and utilized.

Dietary cellulose includes crude fiber, semi-crude fiber, and lignin. Dietary cellulose, which was considered as "waste" in the past, is a substance that is not digested and absorbed, and is now considered to have an important role in protecting human health and prolonging life, and is therefore called a seventh nutrient.
