What are the functions of dietary fiber? There are all kinds of food. Only with a good diet can our bodies be healthier. Dietary fiber is not easily digested and absorbed by other people's gastrointestinal tract. What are the functions of dietary fiber?
What are the functions of dietary fiber? 1 Efficacy 1: Reduce blood cholesterol and prevent cardiovascular diseases.
High fat and cholesterol are the main causes of cardiovascular diseases. Cholesterol in the liver is converted into cholic acid by metabolism, and cholic acid reaches the colon to digest and absorb human fat, and then is digested and absorbed by the colon and returned to the liver to be converted into cholesterol. Dietary fiber can produce colloidal substances in the colon and then surround cholic acid. Cholic acid surrounded by dietary fiber can not be digested and absorbed back to the liver by small intestine cavity, but excreted by digestive system.
Therefore, in order to digest and absorb the food that continues to enter the colon, the liver can only rely on digesting and absorbing cholesterol in the blood to supplement the consumed cholic acid, thereby reducing the cholesterol in the blood, which is conducive to reducing the prevalence of coronary heart disease, stroke and other diseases caused by high cholesterol.
Efficacy 2: Improve blood sugar level and turn it into the reflection and prevention of liver cancer.
Many scientific studies have confirmed that some water-soluble chemical fibers can reduce the rise of postprandial blood sugar and insulin glargine. This is because salicylic acid in dietary fiber can prolong the waiting time of food in the stomach, increase the gastric emptying time, and slow down the digestion and absorption of glucose, so that the body's blood sugar index is not easy to increase significantly after eating. And reduce the body's demand for insulin glargine, which is conducive to the improvement of diabetes.
Efficacy 3: Improve intestinal function, promote gastrointestinal peristalsis and avoid constipation.
The effects of dietary fiber on intestinal function include: reducing excreta according to time, increasing the number of excreta and defecation frequency, diluting intestinal contents, and providing substrates for all beneficial bacteria normally existing in the intestine to produce alcohol.
Water-soluble dietary fiber is like a hygroscopic sponge in the intestine, which can increase the moisture content of excreta and make it loose. In addition, dietary fiber can also promote the intestinal peristalsis of the stomach, thus accelerating the defecation speed and producing the effect of naturally moistening the intestines. The reduction of stool time is conducive to reducing the growth and development of harmful bacteria in the intestine and preventing many bile acids from turning into carcinogens.
Efficacy 4: Controlling rest weight is beneficial to lose weight.
Dietary fiber expands after absorbing water, which makes people feel full and reduces food intake. In addition, dietary fiber can also reduce the microbial utilization rate of three nutrients in food, so it is very helpful for obese people to control their resting weight.
What are the functions of dietary fiber? 2 1. Prevent obesity.
Multi-fiber diet can increase the volume of stomach contents and produce satiety, thus reducing the total amount of food and energy intake, which is conducive to controlling weight and preventing obesity.
2, cathartic laxatives
Multi-fiber diet can soften and increase stool, promote intestinal peristalsis, promote intestinal emptying, keep stool unobstructed, and normalize intestinal function. However, people who mainly eat high protein, high fat and other fine foods, do not eat or rarely eat fiber diet, are prone to constipation, which makes harmful substances in feces stay in the intestine for a long time, irritate the intestinal wall or be absorbed into the blood, causing harm to the human body.
3. Reduce dependence on insulin.
Dietary fiber can affect blood sugar level. The fasting blood glucose level or oral glucose tolerance curve of people who regularly eat dietary fiber is lower than that of people who eat less. It is observed that the increase of postprandial blood sugar in diabetic patients decreases after taking pectin or bean gum. Dietary fiber, such as miscellaneous grains, wheat bran, beans and vegetables, can reduce the amount of urine sugar and the amount of insulin needed by diabetic patients.
4. Prevent the formation of gallstones and regulate blood lipids.
Most gallstones are caused by supersaturation of cholesterol in bile. When bile acids and cholesterol are out of balance, small cholesterol crystals will precipitate and form gallstones. Dietary fiber can reduce the concentration of cholesterol in bile and serum, thus reducing the saturation of bile cholesterol and the prevalence of gallstones.
Dietary fiber can also regulate blood lipid, but only some soluble dietary fibers, such as gum and soybean gum, have obvious lipid-regulating effect, while insoluble dietary fibers, such as wheat bran, sucrose residue and synthetic cellulose, have no such effect.
Step 5 Prevent colon cancer
High-fat foods, such as meat, will make anaerobic bacteria multiply in the intestine and degrade neutral or acidic steroids, especially cholic acid, cholesterol and their metabolites. Metabolites such as cholic acid increased in feces may be carcinogens.
Dietary fiber can inhibit the activity of anaerobic bacteria, promote the growth of aerobic bacteria and reduce the production of cholic acid in large intestine. Not only that, dietary fiber can also dilute the toxic substances in the intestine through its filling function, making the feces soft and shortening the time of passing through the intestine, thus avoiding the carcinogen from contacting with the susceptible intestinal mucosa for a long time and reducing the possibility of canceration.
What are the functions of dietary fiber? 3 dietary fiber powder is not suitable for people:
A group of people have dry stools and habitual constipation.
For this kind of people, due to insufficient dietary fiber intake, dietary fiber can occasionally increase the ability to digest and absorb water. When stored in a certain amount, it will stimulate the intestinal cavity, generate defecation awareness, promote gastrointestinal defecation, and reduce the waiting time of ingredients in the stomach.
People with abdominal distension and indigestion.
Because the intake of dietary fiber in the daily diet structure is less, which slows down gastrointestinal peristalsis, it is necessary to increase the intake of dietary fiber to promote intestinal peristalsis and improve gastrointestinal digestion.
People with lower abdomen, obesity and obesity.
This kind of food prefers high-calorie food with high fat content and doesn't like sports very much. Increasing the dietary fiber content in the diet can reduce the energy intake, reduce the digestion of nutrients in the gastrointestinal tract, and finally make the body consume fat, thus playing a role in losing weight.
Cardiovascular and cerebrovascular diseases such as hypertension, hyperlipidemia, arteriosclerosis and hypercholesterolemia are the main groups of cardiovascular and cerebrovascular diseases.
A balanced diet requires a certain amount of dietary fiber. At the same time, dietary fiber can suck away excess body fat in the stomach and reduce the digestion and absorption of sugar, thus achieving the functions of cleaning blood, lowering blood pressure, blood sugar level, blood sugar and lowering high cholesterol. Thereby reducing the incidence of certain diseases.
Diabetic patients, especially those with abnormal postprandial blood sugar.
Soluble dietary fiber can absorb moisture and expand, and its volume can be increased by dozens of times, resulting in gelatinous substances. On the one hand, the medicine can make people feel full, on the other hand, it can prolong the time of food staying in the stomach, slow down the speed of sugar digestion and absorption, prevent sudden hyperglycemia, and help stabilize the condition of diabetic patients.
The spots are calm and calm, the face is dark yellow, the skin moisture is less, and people have acne.
Dietary fiber supplements can improve skin problems. Dietary fiber can help remove unnecessary oxygen free radicals in the gastrointestinal tract, and has antioxidant effect, reducing the damage of gastrointestinal somatic cells. Long-term consumption can prevent aging. Dietary fiber can also inhale toxic substances in the stomach, inhibit the human body's digestion of them, and make them excrete quickly.
The old gentleman's pen pal
Old basin friends have many problems, such as gastrointestinal digestion and absorption, constipation and so on. , should be adjusted according to the diet, supplement dietary fiber.
