Precautions for eating sweet potato

1. Sweet potato contains an oxidase, which easily produces a large amount of carbon dioxide gas in human gastrointestinal tract. If sweet potato is eaten too much, it will cause abdominal distension, burping and farting. Sweet potato has a high sugar content. Eating too much can produce a lot of stomach acid, which makes people feel "heartburn".

2. The stomach is stimulated by acid, which strengthens the contraction. At this time, the cardiac muscles at the junction of the stomach and the esophagus relax, and the acid in the stomach flows back to the feeding tube, and people spit sour water. Too much sugar can't be absorbed by the body for a while, and the rest will ferment in the intestine, which will also make the stomach uncomfortable.

3. It is forbidden to eat raw potato after germination. At this time, it is called Phoenix potato, which is highly toxic. In the countryside, some farmers once fed raw potatoes after sprouting to pigs and cows, and there were cases in which pigs and cows died of poisoning.
