Carbonhydrate is the main energy supply material for the human body. For the Chinese, grains and rice are essential staple foods on our table. Northerners are accustomed to eating noodles, and often feel that they are not full after eating rice, while southerners are accustomed to eating rice, and they will also feel hungry after eating noodles. In addition, we often see a type of "sugar" that does not contain energy in our life. Many people have eaten it, but they don't not know this tip. So what kind of sugar does not contain energy?
Those with some knowledge of nutrition should know about six major groups of nutrients, which are protein, fat, carbohydrates, vitamins, minerals and water. Today, the "sugar" we want to talk about is called the seventh nutrient, and its popular name is dietary fiber. Dietary fiber is a kind of polysaccharide, which can neither be digested and absorbed by the gastrointestinal tract, nor can it produce energy.
Dietary fiber is divided into soluble dietary fiber and insoluble dietary fiber. Soluble dietary fiber mainly comes from pectin, algin, konjac, etc., which has the effect of lowering blood lipid, lowering blood sugar, and laxative; insoluble dietary fiber mainly comes from cereals such as oatmeal, brown rice, wheat bran, beans, vegetables, etc. It has the effect of promoting gastrointestinal motility and preventing constipation.
In recent years, due to the improvement of our living standards, too much intake of refined grains ignores the importance of coarse grains, plus sedentary and lack of exercise, resulting in a gradual increase in the risk of constipation, intestinal polyps, and bowel cancer. As a good source of dietary fiber, whole grains can effectively help us improve the intestinal environment and digestive function, and have far-reaching significance for the prevention and treatment of intestinal diseases.
In the field of herbal extracts, psyllium husk is rich in cellulose, and this raw material originating in India is often used in various weight loss products. The orange-flavored drink you often see in the orange barrel is made of this raw material, and it has an excellent effect on laxatives.
