1. Persimmons

The reason is that crab meat is rich in protein, while persimmons contain a large amount of tannic acid. The two substances will react with each other and reduce the activity of digestive enzymes. If it decreases, it is not a big problem for people with normal gastrointestinal function to eat occasionally.

People with weak digestive function or sensitive gastrointestinal tract should not eat this way. Eating crabs and persimmons in large quantities may cause gastrointestinal discomfort such as nausea, vomiting, abdominal pain, diarrhea, etc.

2. Strong tea

Chinese people like to drink tea, and they often like to drink some tea to clear their stomachs when eating greasy food. However, it is generally not recommended to drink a lot of strong tea before and after eating crabs. The principle is similar to eating persimmons. Strong tea contains more tannic acid. People with weak digestive function or sensitive gastrointestinal tract should not eat it together to avoid causing gastrointestinal discomfort.

3. Pears

Pear is a cooling food, and eating it with cold crabs may not be a big problem for people with normal digestive function. If you eat like this, it will damage the spleen and stomach and cause gastrointestinal discomfort, so you should pay special attention to it.

Crabs have long been eating aquatic organisms, aquatic plants, and decayed matter. During processing and eating, remember to remove the gills, stomach, intestines, and heart of the crab, and cook them thoroughly. .

The above-mentioned parts are the breathing and excretion organs of crabs. They contain dirt, bacteria, etc., so they must be cleaned. In addition, after the crab dies, the histidine in the body decomposes a harmful substance called "histamine" and other harmful substances. The longer the death time, the more histamine is produced. Therefore, you should pay attention to the choice when buying crabs and try to avoid dead crabs and boil them overnight. Cooked crabs should be stored at low temperatures in the refrigerator.

Extended information:

The protein contained in crabs and the cholesterol contained in crab roe are relatively high. Excessive consumption at one time is not conducive to human body digestion and absorption. The appropriate intake of aquatic products is 40-75 grams (edible part) at one time, which is equivalent to 100-188 grams of crabs with shells, and it is best not to exceed 3 times a week. A 188-gram shelled crab is roughly equivalent to a 4-pound large crab.

Stored cooked crabs are easily contaminated by bacteria, so the crabs should be steamed and eaten immediately. In case you can't finish it, the remaining crabs must be kept in the refrigerator and eaten at the next meal. They must be reheated or steamed before eating. It is recommended not to eat overnight crabs. Although reheating can kill pathogenic microorganisms, it cannot destroy toxins and is still dangerous.

Some people like to eat raw crabs and drunken crabs because they think they taste more delicious. However, various viruses, bacteria and parasites attached to the crabs will also take the opportunity to enter the human body, which may cause food poisoning. Symptoms include diarrhea, abdominal pain and vomiting.

Although the drunken crabs are soaked in rice wine and white wine, the crabs themselves are still raw, and alcohol cannot completely sterilize them. If the paragonimiasis metacercariae contained in drunken crabs enter the human body and develop into adult worms and lay eggs, in severe cases, they can also parasitize other organs such as the human brain, skin, and liver. Therefore, these two ways of eating should be discarded.
