Persimmons, bananas and oranges should not be eaten together. Persimmon contains a substance called tannic acid. Oranges taste sour and are rich in acidic substances. After eating, there will be a lot of gastric acid secretion, which is easy to produce sediment in the stomach with tannic acid and other ingredients in persimmon, and it is not easy to digest. Persimmons and bananas are cold foods, so you can't eat too much. Eating too much can easily cause bloating, abdominal pain and other reactions. Therefore, it is recommended not to eat persimmons on an empty stomach, and eat persimmons for a while before eating other foods.
