cereal fiber helps prevent diabetes

according to xinhua news agency, washington, april 11, german researchers have found in new research that the water-insoluble fiber contained in whole grains and many vegetables can improve the body's utilization of insulin, thereby helping prevent ⅱtype diabetes.

previous studies have shown that diets with high water-insoluble fiber content can help reduce the risk of diabetes, but the reasons are unknown. to find out the correlation, researchers from the german institute of human nutrition designed different dietary plans for 17 women with overweight to explore the functions of water-insoluble fiber. the researchers asked the women who participated in the study to eat bread rich in water-insoluble fiber for three consecutive days, and then switch to bread with low fiber content for three days. comparative analysis showed that a diet rich in water-insoluble fiber increased the insulin sensitivity of these women.

there are two main categories of dietary fiber: water-soluble and water-insoluble. foods such as oats, beans, apples, berries, etc. are rich in water-soluble fibers, which can be soluble in water to form gel-like substances, which are believed to help lower cholesterol and blood sugar. water-insoluble fiber is insoluble in water and remains basically the same after being digested by the human body. researchers suggest that it is best to take fiber from natural foods.
