In recent years, the incidence of diabetes increases year by year, especially Ⅱ diabetes patients. There were 30 million people in 1985, 120 million in 2000 and 220 million by 2010, and 300 million by 2025. Soluble dietary fiber, such as gluconate fiber, can reduce the effect of diabetes. Studies have shown that dietary fiber can slow the absorption of glucose in the small intestine in at least three ways. Increase the viscosity of intestinal fluid and inhibit the diffusion of glucose; The absorption of glucose in the intestine is reduced by reversible adsorption of glucose. Amylase on starch degradation effect, to extend the time of digestion, reduce glucose release rate, taking 1 nutrients (30 grams) daily than taking metformin hypoglycemic effect is good, without any side effects.
