Hairy crabs are not recommended to eat with foods containing more tannic acid, such as persimmons, black dates, hawthorn and pomegranate.

This is because protein reacts with tannic acid in crabs, producing protein precipitate of tannic acid, which may cause abdominal distension, abdominal pain, nausea, vomiting and other gastrointestinal discomfort. However, whether it will cause gastrointestinal discomfort is related to food intake and personal gastrointestinal function, and it does not necessarily happen. If you eat a small amount occasionally, don't worry too much.

In addition to eating hairy crabs, try not to eat with foods with high tannic acid content, and there are other special taboos to pay attention to.
