Is Soy Fiber Natural Dietary Fiber?

Soybean dietary fiber mainly refers to the general term for those high molecular sugars in soybeans that cannot be digested by human digestive enzymes, including cellulose, pectin, xylan, mannose, etc. Although dietary fiber cannot provide any nutrition to the human body ingredients, but it has important physiological effects on the human body, mainly as follows:

1. Dietary fiber can delay the absorption of sugar, inhibit the rise in blood sugar, and reduce insulin secretion, which has an obvious preventive effect on diabetes;

2. It can hinder the absorption of neutral fat and cholesterol, significantly reducing blood cholesterol levels. At the same time, dietary fiber can adsorb sodium salt, blocking its absorption in the intestine and thus lowering blood pressure;

3. Dietary fiber can promote intestinal peristalsis and prevent constipation and colon cancer;

4. The hydration of dietary fiber can enhance the feeling of satiety, delay and reduce the absorption of nutrients in the small intestine, and can effectively prevent obesity.

Therefore, dietary fiber is recognized by the medical and nutritional circles as the "seventh major nutrient" and an important food component for preventing hypertension, coronary heart disease, obesity, etc.

Functions of soy dietary fiber

1. Prevent obesity.

The relative density of soybean dietary fiber is relatively small, and the volume after absorbing water is large, which has a volumetric effect on the intestinal tract and easily causes a feeling of satiety. Moreover, the presence of soybean dietary fiber affects the body's digestion and absorption of other available components in food, such as carbohydrates, causing human body less likely to feel hungry. So it can prevent obesity.

2. Prevent and treat high blood pressure, heart disease and arteriosclerosis.

Long-term experimental research and clinical data show that one of the risk factors for hypertension, heart disease and arteriosclerosis is hypercholesterolemia. Cholesterol in the blood comes from exogenous intake of food and endogenous synthesis in the body. Its main catabolic pathway is to convert it into cholic acid. Both cholesterol and cholic acid are excreted in the feces. A large number of studies have shown that the excretion of cholesterol and cholic acid is closely related to dietary fiber. The water-soluble dietary fiber in soybeans can significantly reduce blood cholesterol concentration.

3. Prevent diabetes.

Dietary fiber can increase the ability of carbohydrates to stimulate insulin secretion. After eating high dietary fiber, high fiber may increase the sensitivity of tissues to insulin, thereby producing a hypoglycemic effect. Experiments show that soybean dietary fiber reduces the serum triglycerides of rats by 30% compared with the control group. It has obvious blood lipid-lowering properties, can adsorb glucose, delay the absorption of sugar in the body, and effectively inhibit the rapid rise of blood sugar. It also has the effect of inhibiting the secretion of glucagon, improving the sensitivity of peripheral tissues to insulin, and reducing the body's requirement for insulin, thereby having a certain effect on the prevention of diabetes and regulating the blood sugar level of diabetic patients, especially for insulin-dependent patients. The effect on diabetes is obvious.

Since the health effects of dietary fiber were proposed, the focus on dietary fiber in dietary structure has continued to increase; especially in cereal foods, and consumers' pursuit of high-fiber foods is also increasing day by day. The amount of dietary fiber in food reflects the health index of the food to a certain extent. Therefore, the study of dietary fiber has become a research hotspot in the food industry. Soybean dietary fiber is a high-quality natural dietary fiber with large global production and low price, which has a very competitive advantage in the development and utilization of soybean dietary fiber.
