Because persimmon contains more tannic acid and pectin, it will form lumps of different sizes under the action of gastric acid on an empty stomach. If these masses can't reach the small intestine through pylorus, they will stay in the stomach and form gastric persimmon stones. If the stomach persimmon stone cannot be discharged naturally, it will cause digestive tract obstruction, severe pain in the upper abdomen, vomiting and even hematemesis.

2. Don't eat persimmon skin.

Tannic acid in persimmon is mostly concentrated in the skin. When the persimmon is astringent, it is impossible to remove all the tannic acid. If you eat it together with the skin, it is easier to form stomach persimmon stones.

3. Reasonable collocation

In traditional Chinese medicine, crabs and persimmons are cold foods and cannot be eaten together. From the point of view of modern medicine, high-protein crabs, fish and shrimps are easy to solidify into blocks under the action of tannic acid, that is, stomach persimmon stone. At the same time, persimmon should not be eaten after drinking, otherwise long-term consumption will affect digestion and cause intestinal obstruction.

4, suitable for the crowd

As the name implies, some people can eat and some people can't. First of all, the sugar content of persimmon is 10.8%, and it is easy to raise blood sugar if you eat too much. Of course, this is not for diabetics. Also, persimmons are cold fruits, and women with palace cold should not eat them. Also, friends with stomach problems should eat less.

5. Enough.

Tannic acid in persimmon can form compounds that the human body can't absorb with minerals such as calcium, zinc, magnesium and iron in food, so these nutrients can't be utilized, so eating more persimmon can easily lead to the lack of these minerals. Because persimmon has a high sugar content, people feel more full when they eat persimmon than when they eat the same number of apples and pears, which will affect their appetite and reduce their intake of dinner. It is generally believed that it is appropriate to eat no more than 200 grams of persimmons each time without fasting.
