Although sweet potato is a cheap and delicious fitness longevity food, it contains oxidase and crude fiber, which will produce a lot of carbon dioxide gas in human stomach. Because of its high sugar content, eating too much will produce acid in the stomach, causing symptoms such as bloating and heartburn.

Therefore, eating sweet potatoes should pay attention to science. Pay attention to it: eat it cooked, not raw. Because a large number of starch granules contained in sweet potatoes are covered with a tough cell membrane, only when cooked and steamed can the human body digest and absorb them.

Do not eat too much at a time, try to use fine processing, and it is best to eat with rice and noodles to reduce the production of gastric acid and prevent symptoms such as bloating and heartburn.
