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 produce a lot of stomach acid, which makes people feel heartbroken.

The stomach is stimulated by acid and its contraction is strengthened. At this point, the myocardium at the junction of stomach and esophagus is relaxed, and the acid in the stomach flows back to the feeding tube, so people spit acid water. 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.

So the popular sweet potato regimen is not suitable for everyone. If you have diarrhea after eating it, don't force it. Eating brown rice will have the same effect.

Sweet potato should not be eaten with persimmon.

Gao, an expert from China Nutrition Society, said that sweet potatoes and persimmons should not be eaten at the same time in a short time. If there is a lot of food, they should be separated for at least five hours.

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.

If you feel upset in the stomach, you must go to the hospital for gastroscopy to see if there is stomach bleeding or gastric ulcer.

Milk is rich in protein and calcium, while chocolate contains oxalic acid. When they are eaten together, they will combine to form insoluble calcium oxalate, which will greatly affect the absorption of calcium and even lead to dry hair, diarrhea and slow growth.

Because milk is easy to form a covering film on the surface of drugs, minerals such as calcium and magnesium in milk react with drugs to produce water-insoluble substances, thus affecting the efficacy.
