First of all, sea cucumber can't be eaten with grapes, because there are more fruit acids in grapes. If patients eat these two foods together, it may lead to gastrointestinal mucosal damage, and even affect the absorption of sea cucumber in the gastrointestinal tract, and it is impossible to repair the intestine. In addition, sea cucumbers can't be eaten with persimmons, because persimmons contain more tannic acid, and protein in sea cucumbers may interact with tannic acid to form a precipitate, thus causing adverse diseases such as stones.
