Nutritional function of soybean dietary fiber
Abstract: Dietary Fiber: The Body’s Scavenger. It is a polysaccharide, but it is not a carbohydrate. It cannot be digested and absorbed by the gastrointestinal tract, nor can it produce energy, but it is extremely important to the human body. It is dietary fiber.
Soybeans are also rich in dietary fiber and have many nutritional functions, which are very beneficial to the body.

1. Regulate blood lipids
Soybean dietary fiber has the ability to bind and exchange cations, and can exchange ca2+, pa2+, etc. During ion exchange, the instantaneous concentration of cations is changed, which acts as a dilution, so it affects the pH value, osmotic pressure and redox site of the digestive tract, forming an ideal buffer environment.
2. Reduce cholesterol
Soybean dietary fiber can exchange with NA+ in the intestinal tract, which promotes the elimination of K+ and NA+ in the urine and feces, thereby reducing the NA+/K+ value in the blood, which directly reduces blood pressure. Thus prevention and treatment of high blood pressure, heart disease and arteriosclerosis. The excretion of cholesterol and bile acid has a very close relationship with dietary fiber, and the water-soluble dietary fiber in soybean fiber can significantly reduce blood cholesterol concentration.
3. Improve blood sugar
Soybean dietary fiber can prevent and treat diabetes and has the effect of regulating blood sugar. Its mechanism of action is that soybean dietary fiber can form a network structure in the intestine, increase the viscosity of intestinal juice, make food and digestive juice unable to fully contact, hinder the diffusion of glucose, and make glucose Absorption slows down, thereby slowing glucose absorption and lowering blood sugar levels. Improve glucose tolerance and reduce the dosage of blood sugar drugs, play a role in the prevention and treatment of diabetes. It can inhibit and regulate the increase of insulin and blood sugar levels in patients with impaired glucose tolerance. It can promote the absorption of water in the gastrointestinal tract of the human body, delay the absorption of glucose, and at the same time make people feel full, which is beneficial to diabetic and obese patients.
4. Improve colorectal function to prevent colon cancer
Soybean dietary fiber can affect the function of the large intestine, and its effects include shortening the transit time of food in the large intestine, increasing the amount of stool and the number of bowel movements, diluting the contents of the large intestine, and providing a fermentable substrate for the flora normally present in the large intestine. Preventing colon cancer Dietary fiber can promote intestinal peristalsis, reduce the contact time of harmful substances with the intestine, and can effectively prevent colon cancer.
5. Reduce the effect of harmful substances
Soybean dietary fiber has the effect of adsorbing heterocyclic amine compounds and reducing its biological activity. Heterocyclic amines are a kind of isolating from the pyrolysis of proteins, peptides and amino acids when cooking and processing protein foods, and have mutagenic and carcinogenic aminoimidazolium heterocyclic aromatic stem compounds. Therefore, increasing the intake of soybean dietary fiber has a positive effect on preventing the possible harm of heterocyclic amines.
