The main ingredient of crab meat is protein, and it also contains calcium, phosphorus, iron and vitamin A. Therefore, it is not only delicious, but also nutritious. However, if it is eaten with fruit, it is easy to combine with tannic acid contained in fruit to form tannic acid protein, which is not easy to digest, aggravates gastrointestinal burden and may also cause symptoms such as diarrhea. Therefore, don't eat fruits immediately after eating crabs, especially persimmons and other fruits with high tannin content.

Extended data:

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 advisable to eat no more than 200 grams of persimmons every time when you are not on an empty stomach.
