What is dietary fiber

Dietary fiber has five main roles:

One, to prevent constipation, promote intestinal peristalsis.

Secondly, it facilitates weight loss.

Three, the prevention of colon and rectal cancer.

Four, the prevention and treatment of hemorrhoids.

V. Improve diabetes symptoms, oral and dental function.

Sixth, the prevention and treatment of gallstones, lowering blood lipids, preventing coronary heart disease.

Dietary fiber definition: dietary fiber is non-starch polysaccharide of a variety of plant matter, mainly from the cell walls of plants and animals, including cellulose, lignin, wax, chitin, pectin, β-glucan, inulin and oligosaccharides, etc., usually divided into non-soluble dietary fiber and water-soluble dietary fiber two categories.

Nutritional value: human dietary fiber is mainly contained in vegetables and roughly processed cereals, although it can not be digested and absorbed, but has to promote intestinal peristalsis, facilitating fecal discharge and other functions. Herbivores rely on their digestive tract **** microbial cellulose decomposition, so that can be absorbed and used. Dietary cellulose includes crude fiber, semi-crude fiber and lignin. Dietary cellulose is a substance that is not digested or absorbed, and used to be considered a "waste product", but now it is considered to play an important role in protecting human health and prolonging life.

Harms of dietary fiber: Large amounts of fiber supplementation may lead to hypoglycemic reactions. A large amount of supplemental fiber, may reduce the digestive absorption rate of protein. A large amount of supplemental fiber, may affect the absorption of calcium, iron, zinc and other elements. A large number of supplemental fiber, may make the gastrointestinal tract of diabetic patients "unbearable".
