Oligosaccharides are low-calorie foods with low calories, which cannot be digested and absorbed by human body, raise blood sugar, turn into fat and cause dental caries. Molecules are always connected by β-(2 1) glycosidic bonds, which are not digested by human digestive juice and are hardly absorbed by human small intestine. They have many physiological functions, including relaxing bowels, regulating blood sugar concentration and reducing blood fat.
Fructooligosaccharides can promote the secretion of propionic acid by beneficial bacteria, thus increasing the content of short-chain fatty acids and lactic acid, strengthening intestinal peristalsis, increasing cholesterol excretion and inhibiting cholesterol production.
Xiuyuan can inhibit the growth of pathogenic bacteria, expel accumulated putrefaction, reduce the secondary absorption of human body in intestinal tract, avoid the invasion of toxins on the skin, protect the skin and reduce the formation of spots and acne; At the same time, changing the PH value of intestine can improve the absorption of trace elements such as calcium, iron and zinc, improve cell renewal, make skin ruddy and more elastic, and help to improve the effect of caring skin.
