Dietary fiber What are the main functions of dietary fiber?

Main functions of dietary fiber: 1. Dietary fiber for treating diabetes can improve the sensitivity of insulin receptor and improve the utilization rate of insulin; Dietary fiber can wrap the sugar in food and make it gradually absorbed, which has the function of balancing postprandial blood sugar, thus regulating the blood sugar level of diabetic patients and treating diabetes.

2. Prevention and treatment of coronary heart disease The increase of serum cholesterol content will lead to coronary heart disease. The excretion of cholesterol and cholic acid is closely related to dietary fiber.

Dietary fiber can be combined with cholic acid, so that cholic acid can be excreted quickly. At the same time, the combination of dietary fiber and cholic acid will promote the conversion of cholesterol into cholic acid, thus reducing the cholesterol level. 3, antihypertensive effect Dietary fiber can absorb ions and exchange with sodium and potassium ions in the intestine, thereby reducing the proportion of sodium and potassium in the blood, thus lowering blood pressure.

4. Anti-cancer effect Since the 1970s, there have been more and more reports about the anti-cancer effect of dietary fiber, especially the relationship between dietary fiber and digestive tract cancer. 5, weight loss treatment of obesity dietary fiber replaces the number of certain nutrients in food, reducing the total intake of food.

Dietary fiber promotes the secretion of saliva and digestive juice, fills the stomach, absorbs water and swells, which can produce satiety and inhibit the desire to eat. Dietary fiber is combined with some fatty acids, so that fatty acids cannot be absorbed when passing through the digestive tract, thus reducing the absorption rate of fat.

6. Dietary fiber for constipation has strong water holding capacity, and its water absorption rate is as high as 10 times. After absorbing water, the volume of intestinal contents is increased, which makes the stool loose and soft, and it will be smoother and more labor-saving when passing through the intestine.

At the same time, dietary fiber, as a foreign body in the intestine, can contract and peristalsis the intestine, accelerate defecation and play a role in treating constipation. .
