Personally, I think there is tannic acid in persimmon.
It is best not to eat with some high-protein foods.
Like some seafood rich in protein, such as crab, fish, shrimp, etc.
Protein is easy to solidify into a ball under the action of tannic acid, and will remain in the stomach, which is the stomach persimmon stone.
Persimmons can't be eaten with sweet potatoes and spinach.
If persimmon is eaten with sweet potato and spinach,
It is likely to lead to an increase in stomach acid.
Then stomach acid will coagulate when it meets tannin and pectin.
Form an insoluble mass, that is, stomach stones.
Persimmons had better not be eaten with vinegar.
If persimmon is eaten with vinegar,
Persimmon gum in persimmon reacts with acetic acid to form a lump, which remains in the stomach of human body.
It will also cause certain harm to the human body.
Thank you.
