2. Absorb toxins. In the process of food digestion and decomposition, a large number of toxins will inevitably be produced. These harmful substances will stimulate the mucosal epithelium in the intestinal cavity for a long time, causing mucosal inflammation. Absorbed into the blood, it can increase the detoxification burden of the liver. Cellulose forms a dense network when it meets water in the gastrointestinal tract, and absorbs organic matter, inorganic matter and water, which plays an important role in maintaining the normal flora structure of the gastrointestinal tract. At the same time, the toxins in intestinal contents will be absorbed by cellulose, and the chances of intestinal mucosa contacting with poisons will be reduced, and the absorbed blood volume will also be reduced.
3. Protect the skin. When the blood contains toxic substances, the skin becomes a place where it abandons waste. Facial acne is formed because there are too many acidic substances and saturated fat in the blood. The skin color of people who are often constipated is yellow, which is also because the feces stay in the intestine for too long, and toxic substances are absorbed through the intestinal wall, which makes the blood contaminated with toxins. People who smoke too much look like ashes, which is also caused by the above reasons. Dietary fiber can stimulate intestinal peristalsis, make waste excreted in time, and reduce the toxic effect of toxins on intestinal wall, thus protecting the skin.
4. Reduce blood lipids. Some components in dietary fiber can be combined with cholesterol if colloid can, and lignin can be combined with cholic acid, so that it can be directly discharged from feces, thus consuming cholesterol in the body to supplement cholesterol consumed in bile, thereby reducing blood lipid. Dietary fiber absorbs water in the intestine to dilute the intestinal contents, reduce the concentration of bile and cholesterol, and promote the growth and reproduction of bacteria normally resident in the intestine; These normal bacteria can also convert cholesterol into feces during reproduction, which is helpful to reduce the occurrence of coronary heart disease.
5. control blood sugar. Some people think that one of the reasons for diabetes is that there is too little cellulose in food. Foods containing a lot of dietary fiber provide little energy to the human body. Pectin in fiber can prolong the residence time of food in intestine, reduce the absorption rate of glucose, and prevent the blood sugar from rising sharply after meals, which is beneficial to the improvement of diabetes. At the same time, high fiber food can reduce insulin secretion within the physiological range and reduce food intake; In addition, high-fiber food can reduce the demand of diabetic patients for insulin or general oral hypoglycemic drugs, while still effectively controlling blood sugar concentration. Can be used for preventing and treating diabetes.
6. Protect your mouth. Modern people eat more and more delicate and soft food, so the activities of using oral muscles and teeth are correspondingly reduced. Increasing the cellulose in the diet can increase the chances of chewing with oral muscles and teeth, wash away the dirt in the teeth and exercise the gums. If you persist for a long time, your mouth will be healthy and your function will be improved.
7. Treat polyps. With the accelerated pace of life, there are more and more patients with intestinal polyps. Especially in developed countries, almost a quarter of adults suffer from this disease. I used to treat with low dietary fiber, because I was afraid that dietary fiber would stimulate the affected area, and the effect was not obvious. On the contrary, the treatment of high dietary fiber is effective. Facts show that the high incidence of polyps is related to the low intake of dietary fiber.
8. Prevention and treatment of stones. The formation of gallstones is related to the high content of bile cholesterol. Dietary fiber can bind cholesterol, promote the separation and circulation of bile, and thus prevent the formation of gallstones.
9. Prevent breast cancer. Epidemiological studies have found that breast cancer is related to high fat, high meat content and low dietary fiber. This may be caused by excessive fat in the body promoting the synthesis of some hormones and stimulating the variation of breast cells. However, the intake of high dietary fiber will reduce the absorption of fat and inhibit the synthesis of these hormones, thus preventing breast cancer.
10 to prevent constipation. Food fiber has a large volume, which can promote intestinal peristalsis, and the water in it is not easily absorbed, so it has a laxative effect. Dietary fiber can expand the volume of feces, improve water absorption, promote intestinal peristalsis, accelerate the advancement of feces in the intestine, make defecation timely, reduce the contact time between intestinal cavity wall and ingested carcinogens, and eliminate the risk of colorectal cancer. Prevention and treatment of hemorrhoids.
1 1, preventing intestinal cancer. Carcinogens exist widely in nature and will inevitably enter the intestine with food and water. At the same time, some bacteria may have the ability to synthesize polycyclic hydrocarbons or reduce nitrate to nitrite. There are a large number of bacteria in human large intestine, which can produce many poisons such as amine, phenol and ammonia. If there is less cellulose in the food, the feces are small in size, the viscosity increases, and they stay in the intestine for a long time, these poisons will have toxic effects on the intestinal wall, which can be absorbed into the blood circulation through the intestinal wall like water, thus affecting the whole body. After food fiber enters the intestine, it can increase the volume of feces and contain more water, dilute the toxin concentration and stimulate intestinal peristalsis, accelerate the emptying speed of food in the intestine, shorten the residence time of toxic substances in food in the intestine, promote bile acid excretion, and keep feces acidic, which is beneficial to the prevention of colorectal cancer. Cellulose in vegetables is fermented in intestine to produce short-chain fatty acids such as butyric acid, which can promote cell differentiation and prevent intestinal cancer. Cellulose can increase the number of chews, thus increasing saliva secretion, which is an important substance for cancer prevention. When Europeans and Americans ingest cellulose, it is only 1/6 of that of Africans. Of the 654.38 million people in the United States, 42 suffer from colorectal cancer, while only 8 people in Africa suffer from colorectal cancer.
12, increase nutrition. Dietary fiber absorbs water in the intestine, dilutes intestinal contents, reduces bile concentration and promotes the growth and reproduction of normal resident bacteria in the intestine; E. coli in the intestine can use cellulose to synthesize indispensable life substances such as pantothenic acid, nicotinic acid and riboflavin.
Although people can't digest food fiber like herbivores, they can decompose some fiber through intestinal bacteria. E. coli, for example, can synthesize vitamin B pantothenic acid, inositol and vitamin K from fibers and absorb them by human body.
Dietary fiber can also reduce the prevalence of gastric cancer and lung cancer, which has a good effect on preventing coronary heart disease.
