Fiber food refers to foods with high dietary fiber content (2%~20%). Dietary fiber can resist intestinal digestive enzymes, but it can be decomposed by bacterial enzymes. Dietary fiber can be divided into insoluble and soluble categories. Insoluble dietary fiber includes cellulose, hemicellulose and lignin, while soluble dietary fiber includes pectin, seaweed gum, bean gum and stump gum. Most dietary fibers are carbohydrates, which cannot be digested by the stomach, but can promote intestinal peristalsis and help the stomach digest and absorb other nutrients. [ 1]

brief introduction

Among them, dietary fiber is divided into water-soluble dietary fiber and water-insoluble dietary fiber. The former is gum, gum and mucus, which is soluble in water and mainly exists in fruits, oats, barley and some beans. Water-soluble fiber can slow down digestion and excrete cholesterol as soon as possible, so it can control blood sugar and cholesterol in blood beyond the ideal level, and can also help diabetic patients reduce insulin and triglycerides. Most dietary fibers are insoluble in water, such as cellulose and hemicellulose. Animal experiments show that plant fiber is more beneficial to human body than grain fiber. Insoluble fiber can reduce the risk of intestinal cancer, prevent constipation and diverticulitis by absorbing toxic substances in food, and reduce toxins discharged by digestive tract bacteria. Most plants contain water-soluble and water-insoluble fibers, so a balanced intake of water-soluble and water-insoluble fibers in the diet can obtain different benefits. [2]
