Oatmeal is rich in dietary fiber.
Oats are one of the few cereals that contain both soluble and insoluble dietary fiber. Different oats have different dietary fiber contents.
Some bulk oatmeal is mainly insoluble dietary fiber and takes a long time to cook, which takes 15 to 20 minutes. However, most bagged oatmeal is mainly soluble dietary fiber and can be boiled for three minutes.
Oatmeal, which is mainly insoluble dietary fiber, is more advantageous in increasing the weight of stool and preventing and improving constipation. Because such dietary fiber cannot be digested by the gastrointestinal tract or broken down by bacteria in the large intestine, the fiber structure is full of gaps, absorbs water, and expands, pushing food residues in the intestines out. Moreover, it can help absorb and expel harmful substances in the intestines and reduce the risk of colon cancer. ?
Oatmeal, which is mainly composed of soluble dietary fiber, is more capable of preventing rapid rise in blood sugar and lowering plasma cholesterol. The soluble dietary fiber in oats is mainly beta-glucan, usually in the form of oat gum. When cooked, you will find that oatmeal is very sticky. Not only can it delay the emptying time of the stomach and prevent rapid rise in blood sugar, it can also bind bile and neutral cholesterol to promote their excretion from the body.
Different oats have different characteristics. Buy and eat them according to your own conditions.
