Sweet potato contains an oxidase, which easily produces a large amount of carbon dioxide gas in human gastrointestinal tract. Eating too much sweet potato will make people bloat, burp and fart.

Sweet potato has a high sugar content. Eating too much will stimulate gastric acid secretion and make people feel heartbroken. Because the stomach is stimulated by excessive gastric acid, the contraction is strengthened, and the gastric acid can flow back to the feeding tube, leading to acid vomiting.

Too much sugar can't be absorbed by the body for a while, and the rest will ferment in the intestines and make the stomach uncomfortable.

Precautions for eating sweet potatoes:

1. Sweet potatoes must be steamed before eating, because the starch particles in sweet potatoes are not destroyed by high temperature and are difficult to digest.

2. Sweet potato and persimmon should not be eaten at the same time in a short time. If the amount of food is large, it should be at least five hours apart. If eaten at the same time, the sugar in sweet potato will ferment in the stomach, which will increase the secretion of gastric acid and precipitate and condense with tannin and pectin in persimmon to produce lumps. When the amount is serious, it can cause gastrointestinal bleeding or gastric ulcer.
