Promote the growth of probiotics. Studies have confirmed that indigestible oligosaccharides and non-starch polysaccharides such as inulin, fructooligosaccharides and dextran have shown the characteristics of "prebiotics", which can not only stimulate the growth of intestinal beneficial bacteria, such as Bifidobacterium and lactic acid bacteria, but also help to produce butyric acid.
Protect the intestines. Dietary fiber can affect the permeability of cell bypass and lead to various intestinal inflammatory reactions, and some dietary fiber can adjust the symptoms of irritable bowel syndrome. Other related effects include reducing the activity of harmful bacterial enzymes, reducing the levels of phenol and peptide degradation products, and forming cellular antioxidants.
Regulate blood sugar. The prevention of diabetes can not be separated from dietary fiber, and most dietary fiber has the function of lowering blood sugar. Studies have shown that the intake of total dietary fiber has a direct impact on type II diabetes.
Extended data:
The number of people suffering from "rich diseases" such as hypertension, hyperlipidemia and diabetes in China is increasing year by year. The main reason is that they eat too much fat and energy. In order to cope with these diseases, high-fiber foods are favored by many people, especially girls.
Healthy living really requires us to eat food containing dietary fiber, but it should also be moderate, otherwise it will hinder the body's absorption of other nutrients and produce adverse reactions such as malnutrition and decreased immunity.
Characteristics of dietary fiber: dietary fiber is the main component of plant cell wall, including cellulose, hemicellulose, lignin and various plant gums, which can not be absorbed by small intestine and directly enter large intestine. Dietary fiber is super absorbent fiber, which absorbs 5-25 times more water than itself.
