The claim that drinking alcohol after eating persimmons causes stones is too one-sided. But eating persimmons on an empty stomach, especially in some people with poor gastrointestinal dynamics may form stomach stones. Gastric stones are usually formed due to improper diet, when the food contains some difficult to be digested substances, such as metal, sediment, animal hair, etc., due to its nature, it is difficult to empty, short-term easy to form gastric stones. Among them, tannic acid can react with the proteins in the stomach leading to the formation of stones. It should be noted that the persimmons sold on the market are ripe, after de-astringent treatment, the content of ellagic acid within the very low, moderate consumption does not usually lead to stomach stones. But if you eat persimmons on an empty stomach, or eat persimmons when the gastrointestinal power is poor may form stomach stones. So after eating persimmons and drinking alcohol lead to stones, there is no scientific evidence, but it is not recommended to eat persimmons after drinking a lot of alcohol.
