Persimmons are rich in persimmon gum, which when eaten with acid will produce some lumps, which are difficult to digest, and if left in a person's stomach for a long period of time will lead to stomach stones. Therefore, persimmons can not be consumed with vinegar, not only that, try not to eat vinegar before and after eating persimmons.

Persimmons contain a substance called ellagic acid, which together with protein will solidify into lumps, which is what we call stones. Therefore persimmons should not be consumed with foods such as fish and shrimp that are high in protein.

Persimmon contains more pectin and ellagic acid, they meet with acidic substances will produce some hard lumps that are difficult to dissolve, and sweet potatoes and spinach contain a lot of starch, they will produce a lot of stomach acid in the stomach after digestion, so persimmons can not be eaten with spinach, sweet potatoes, potatoes and other high starch food, so as to avoid the formation of stomach stones.
