Persimmon and seafood should not be eaten together; If you eat persimmons while eating seafood, you will have symptoms such as vomiting, abdominal distension, abdominal pain and diarrhea. Because persimmon contains tannic acid, protein in aquatic products will precipitate and solidify, forming indigestible substances. At the same time, tannic acid also has the effect of collecting sword, which can inhibit the secretion of digestive juice, make solidified substances stay in the intestine for a long time, and then cause fermentation. Therefore, after eating seafood, you should eat persimmons at intervals of more than 4 hours.
