Can crabs and persimmons be eaten together?

I haven't thought about this sudden problem carefully, but I'd rather believe it than believe it, and I'd better be cautious. This young man is a little gourmet. He likes persimmons and crabs, and he is quite stubborn. He was obviously dissatisfied with my ambiguous answer. He conducted an experiment alone. He deliberately ate a hairy crab and a persimmon, and didn't eat anything else. He lay in bed waiting for the appearance of "Xiangke" reaction. After about an hour, there was no adverse reaction, but I felt hungry and had a delicious dinner. In autumn, crabs and persimmons are listed together. Folks have always said that this is a pair of "food for enemies", and you must never eat it together. The saying of "containing each other" has been circulating for many years. "Crabs are like persimmons" comes from the life experience of the ancients. In my opinion, the key to the similarity between these two foods lies in the persimmon itself, and crabs can't be blamed for going too far. It is generally okay for healthy people to eat two big crabs at a time. Persimmons are not. Chinese medicine believes that persimmon is a cold food. Moreover, persimmon contains a lot of pectin and persimmon gum phenol, especially in persimmon core and persimmon skin, which can be discarded, and persimmon core is the essence of persimmon meat, and no one wants to discard it; Immature persimmons also contain red tannins, which will condense into lumps when encountering gastric acid. If you eat too many persimmons, blood clots will even turn into lumps-stomach persimmon stones, which will do harm to your stomach. It happened that crab is also a cold food, crab meat is rich in protein, persimmon contains a lot of tannins, and protein will solidify when it meets tannins. But there are also many foods that are cold and rich in protein, such as ducks that people often eat. Therefore, only mentioning the similarity between persimmons and crabs, but not mentioning that protein-rich foods such as persimmons and ducks should not be eaten together, will definitely make people who love to scrutinize questions. The young man ate crabs and persimmons at the same time, safe and sound. I think there are preconditions: first, he only ate a persimmon; Second, young people have a good digestive function. Persimmon and crab meat are quickly discharged into the duodenum after preliminary digestion. The author thinks that crabs and persimmons should be analyzed in detail. The key is to eat persimmons carefully. Even if persimmon is eaten alone, if it is eaten too much, even if it is not eaten at the same time, it may cause trouble to the stomach. There are many "pilgrims" foods in ancient medical books and folklore, and crabs and persimmons make sense. Compendium of Materia Medica lists that crabs avoid persimmons, crabs avoid oranges, pork avoid beef, quail and mutton avoid vinegar, and chicken avoid raw onions, glutinous rice and carp, which cannot be explained. In addition, crucian carp avoid sugar, garlic and peanuts avoid cucumber, which are all puzzling. We should make a concrete analysis of this statement of seven taboos and eight taboos with a scientific attitude, and discard the false and retain the true.
