Can you eat crab after eating dried persimmon?
Generally, it is not recommended to eat crabs after consuming dried persimmons. The detailed explanation is as follows:

Dried persimmons are cold in nature and rich in tannic acid, while crabs are also cold in nature and are high-protein foods. When tannic acid combines with protein, they form indigestible precipitates that can accumulate in the gastrointestinal tract, increasing digestive burden and easily causing symptoms such as abdominal distension, abdominal pain, and diarrhea. These adverse reactions are especially pronounced in individuals with weak gastrointestinal function. Moreover, combining two cold-natured foods further irritates the gastrointestinal mucosa, intensifying physical discomfort.
After eating dried persimmons or crabs, it's advisable to drink a cup of warm water to help soothe the stomach and alleviate the cooling effect. There should be at least a 4-hour interval between consuming these two foods, allowing sufficient time for digestion. Additionally, intake should be moderated in daily consumption, as dried persimmons are high in sugar and crabs are cold in nature—excessive consumption of either can place additional strain on the body.
