Is Soy Dietary Fiber Good For The Human Body?
2025-05-26 18:07:24
Soy Dietary Fiber mainly refers to the general term for high-molecular sugars in soybeans that cannot be digested by human digestive enzymes, mainly including cellulose, pectin, xylan, mannose, etc. Although dietary fiber cannot provide any nutrients for the human body, it has important physiological functions for the human body. Therefore, the medical and nutritional communities recognize dietary fiber as the "seventh nutrient". It is also rich in nutrition, unique in flavor, safe and convenient to eat, and is the leader in dietary fiber.
How Does Soy Dietary Fiber Promote Intestinal Health?
Soy Dietary Fiber has many benefits for intestinal health, and its mechanism of action involves promoting intestinal peristalsis, regulating the balance of flora, and enhancing intestinal barrier function.
Promote intestinal peristalsis and prevent constipation: Soy dietary fiber can increase the volume of stool by absorbing water and swelling, stimulate the contraction of intestinal smooth muscle, and accelerate the discharge of food residues. This physical effect can shorten the residence time of feces in the intestine, reduce the contact between harmful substances and intestinal mucosa, and thus reduce the risk of constipation.
Regulate the balance of intestinal flora: It can be used by probiotics in the intestine to promote the growth and reproduction of probiotics, such as bifidobacteria and lactic acid bacteria. These beneficial bacteria can inhibit the growth of harmful bacteria, maintain the balance of intestinal flora, enhance intestinal immunity, and help prevent intestinal infection and inflammation.
Improve intestinal function and metabolism: SCFAs promote the expression of tight junction proteins in colon epithelial cells, reduce intestinal permeability, prevent toxins and pathogens from entering the blood circulation, and reduce the risk of systemic inflammation. By adsorbing bile acid, cholesterol and other substances, reducing their reabsorption, indirectly supporting the liver's detoxification function, and may also regulate lipid metabolism and reduce fat accumulation in the intestine.
Adsorb harmful substances: It has a certain adsorption capacity and can absorb harmful substances such as fat, cholesterol, toxins in the intestine like a "small magnet", reducing their absorption and retention in the intestine, thereby reducing the risk of intestinal diseases, and also helps to stabilize blood sugar and blood lipids.
Provide energy: After soybean dietary fiber is degraded by microorganisms in the intestine, short-chain fatty acids such as acetic acid, propionic acid and butyric acid will be produced. These short-chain fatty acids can provide energy for intestinal cells, maintain the normal function of intestinal cells, promote the repair and regeneration of intestinal mucosa, and enhance the barrier function of the intestine.
Increase satiety: It can increase the volume and weight of food, slow down the rate of gastric emptying, make people feel full, reduce food intake, help control weight and lose weight, and indirectly have a positive impact on intestinal health.
What Are The Physiological Functions Of Soybean Dietary Fiber?
As an important nutrient, Soy Dietary Fiber has multiple physiological functions for health, although it is not decomposed by human digestive enzymes.
Promote intestinal peristalsis: By increasing the volume of stool and softening stool, stimulating intestinal peristalsis, accelerating the discharge of food residues, thereby preventing constipation and reducing the risk of intestinal diseases.
Regulate intestinal flora: soybean dietary fiber ferments to produce short-chain fatty acids, promotes the growth of beneficial bacteria, inhibits the reproduction of harmful bacteria, improves the balance of intestinal flora, enhances intestinal barrier function, and improves immunity.
Regulate blood sugar: soluble soybean dietary fiber delays the digestion and absorption of carbohydrates, reduces the increase in blood sugar after meals, helps maintain blood sugar stability, and is beneficial to diabetic patients.
Lower cholesterol: soybean dietary fiber absorbs bile acid, promotes bile acid excretion, reduces cholesterol reabsorption, thereby reducing blood cholesterol and triglyceride levels, which is beneficial to cardiovascular health.
Increase satiety: absorb water and swell in the stomach, increase the volume of gastric contents, delay gastric emptying speed, increase satiety, and help reduce food intake and control weight.
In summary, it plays an important role in maintaining digestive health, regulating blood sugar and blood lipids, controlling weight and reducing the risk of disease.
How Does Soy Dietary Fiber Help Lose Fat?
Soy Dietary Fiber plays an important role in helping lose fat, and its mechanism involves multiple physiological processes
Increase satiety and reduce energy intake: Soy dietary fiber absorbs water and swells in the stomach, increasing the volume of gastric contents, thereby prolonging gastric emptying time, making people feel full, reducing hunger and desire to eat. This increase in satiety helps to reduce total energy intake, thereby supporting the fat loss effect.
Regulate intestinal flora and improve metabolism: As a fermentation substrate for beneficial intestinal bacteria, it promotes the growth of beneficial flora and improves the balance of intestinal flora. Healthy intestinal flora helps to improve the host's metabolic status, including fat metabolism, and reduces fat accumulation. At the same time, short-chain fatty acids produced by dietary fiber fermentation may support fat loss by affecting energy metabolism and appetite regulation.
Control blood sugar and reduce the risk of fat accumulation: Dietary fiber will not be digested and absorbed by the intestines and will not cause blood sugar to rise. The fruit acid in it can prolong the residence time of food in the gastrointestinal tract, slow down the body's absorption of glucose, and avoid a sharp rise in blood sugar after a meal. After blood sugar is stabilized, insulin secretion decreases, thereby reducing the chance of fat accumulation.
Reduce fat absorption and lower blood lipids: Bile acid secreted by the liver is a component of digestive juice and can promote the body's absorption of fat and cholesterol. Soy dietary fiber can absorb bile acid, reduce bile acid, and then reduce the absorption rate of fat and cholesterol, which is beneficial to reduce the cholesterol concentration in the blood and reduce the accumulation of fat in the body.
Promote intestinal peristalsis and accelerate waste excretion: By increasing the volume of stool and softening stool, intestinal peristalsis is promoted, and the excretion of food residues and metabolic waste is accelerated. This accelerated excretion process helps to reduce the intestinal absorption of excess fat and toxins, thereby indirectly supporting fat loss.
In summary, soy dietary fiber works together to help reduce fat through multiple mechanisms such as increasing satiety, regulating intestinal flora, reducing fat absorption and promoting intestinal peristalsis.
