Eating crabs is taboo.

1, don't eat persimmons after eating crabs.

Judging from the medicinal properties of food, persimmon crabs are cool and should be eaten together. Cold hurts the spleen and stomach, especially those with deficiency and cold constitution. Persimmon contains tannic acid, and crab is rich in protein. When they meet, they coagulate to produce tannic acid protein, which is not easy to digest, hinders digestive function, makes food stay in the intestine for fermentation, and food poisoning such as vomiting, abdominal pain and diarrhea will occur.

2. Don't drink tea after eating crabs.

When eating crabs, it is best to drink warm yellow wine, and it is best not to drink tea before and after eating crabs. Because there are some bacteria in crab feet and crab gills, drinking vinegar can kill them, and our gastric juice also has certain bactericidal ability, but after drinking tea, it will dilute the gastric juice and the bactericidal effect will be greatly reduced; And tea leaves, like persimmons, also contain tannic acid, which will cause gastrointestinal discomfort when eaten together. Therefore, avoid drinking tea water when eating crabs and within one hour after eating crabs.

You can't drink cold drinks after eating crabs.

Cold drinks such as ice water and ice cream are all cold things, which will lower the temperature of the stomach. Drinking cold drinks after eating crabs will definitely have diarrhea. So you can't drink cold drinks after eating crabs, and you can't drink cold drinks immediately after eating crabs.

Extended data

So far, there is no saying that "crab+tomato = arsenic" in academic circles. Crab is a crustacean, containing pentavalent arsenic, which is harmless to human body, but it will become trivalent arsenic under the action of vitamin C, which is what people call arsenic. In theory, vitamin C does have reducibility, but the reducibility is very limited.

Even outside the human body, it takes at least a few kilograms of vitamin C to reduce pentavalent arsenic in a crab to trivalent arsenic. But this reduction reaction is not feasible in human body. Because the human liver has detoxification ability, once the trivalent arsenic in the body exceeds the standard, the liver will automatically adjust, and the excess vitamin C will not stay in the body, so the reduction process will not be established and people will not be poisoned.
