1. The role of intestinal mucosa has protective effect on the epithelium. If long-term dietary fiber intake is insufficient, the mucous membrane of intestinal tract will appear atrophy, cannot maintain the normal function of the bowel, can cause constipation or diarrhoea.

2, the colon function and the effect of dietary fiber can change intestinal condition, increase the waste discharge, stimulate the intestinal wall, accelerate intestinal peristalsis, shorten the discharge of waste time, for all kinds of constipation has very good effect.

3, the impact on the intestinal flora, can produce short chain fatty acids, which reduce the e. PH value, affect intestinal microbial metabolism, make the flora changes, soluble fiber (like low poly fructose, isomaltooligosaccharide) as food of intestinal bacteria, for the normal growth of beneficial bacteria breeding provides the food security.
