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.

4. Don't eat grapes after eating crabs.

Crabs are rich in protein. If eaten with persimmon, grape, pomegranate, hawthorn, olive and other fruits containing tannic acid, it will not only reduce the nutritional value of protein, but also easily make protein combine with tannic acid to form indigestible coagulum, which will stimulate mucous membrane and cause abdominal pain, nausea, vomiting and other symptoms.

Taboos for drinking milk

1, avoid adding sugar to cook. Many people add sugar when boiling milk, thinking that it can make the sugar melt as soon as possible, but it is very unscientific to put sugar when heating. Because milk contains lysine and sugar contains fructose, these two substances will form a combination-fructosyl lysine at high temperature. This substance can't be digested and absorbed by human body, which destroys the nutritional value of protein. To make matters worse, it may be toxic to human body. Therefore, never put sugar in milk when it is heated. If you want to drink milk with sugar, you can wait until the milk is slightly cold before adding sugar.

2, avoid eating with oranges. Milk is decomposed in the stomach by pepsin and pancreatin, and then absorbed in the small intestine. If milk is eaten with oranges and other fruits with high fruit acid content, protein in milk will have a complex biochemical reaction with fruit acid and vitamin C, which will affect the digestion and absorption of protein in milk and vitamin C in oranges, resulting in abdominal distension, abdominal pain, diarrhea and other adverse reactions, and eating together will not pay off.

3. Avoid adding chocolate. Some people like to eat chocolate with milk to get rid of the strange smell in milk, which is unscientific. Milk is rich in protein and calcium. When eating with chocolate, calcium in milk combines with oxalic acid in chocolate to form insoluble calcium oxalate, which can not only be absorbed by people, but also cause hair dryness, diarrhea and calcium deficiency after a long time. Therefore, the time for drinking milk and eating chocolate should be separated, and it is best to eat carbohydrates such as biscuits and bread when drinking milk.
