Reporter Zheng Chaojing

"Autumn wind, crab fragrance", every year from September to October, is the best time to eat crab. Recently, the reporter visited a number of supermarkets and aquatic product stores in Xifeng District and found that since the Mid-Autumn Festival, crab sales have continued to be hot. Doctors remind that although crabs are delicious, tender and rich in nutrients, they are not "no contraindications" when eating.

"Boss, here are four female crabs and two male crabs." At a hairy crab store on Lanzhou Road, Mr. Zhang, a citizen, is shopping for crabs. "Now is the time to eat crabs, steaming, oil stewing are particularly delicious, crab sales are also very hot." Mr. Luo, the boss, told reporters that the price of crabs this year is more expensive than in previous years, and the price of 2 crabs is 70 yuan per kilogram, and the price of 2.5 crabs is 75 yuan per kilogram. "Although the price has risen, from the beginning of the Mid-Autumn Festival to the National Day, sales have been good, and many citizens will choose crab as a delicacy on the table."

Although the crab meat is thick and delicious, it is not suitable for everyone to eat, and improper eating methods will cause physical discomfort. The reporter learned from the outpatient clinics of several hospitals in the city that every autumn the hospital will usher in a small peak of food poisoning or skin allergies caused by improper eating of crabs.

Mr. Wang, who lives in a small area of Qinghua Avenue, told reporters, "During the National Day with friends to eat, I ate two crabs, I could not drink, I drank tea, and as a result, when I came home at night, I began to feel dizzy and nauseous, vomiting and diarrhea, and chills." "After going to the clinic, the doctor told him that it was caused by eating crab improperly.

What are the taboos for eating crabs, and is there anyone who is not suitable for eating crabs? Zhao Xiaochun, a doctor at Qingyang People's Hospital, reminded that although crabs are delicious, there are many taboos for eating, and you must pay attention to crabs when eating crabs.

Zhao Xiaochun told reporters that it is forbidden to eat raw crabs and dead crabs. Although there are many types of crabs, there are river crabs, lake crabs, sea crabs, river crabs, etc., but they are grown in silt, feeding on animal carcasses and humus, and their body surfaces, gills and gastrointestinal tracts are full of various bacteria. If eaten raw, it is very susceptible to bacterial infection. Therefore, raw crab can not be eaten, must be washed, steamed and cooked thoroughly, in order to eat with confidence. After the crab dies, the bacteria in its body will rapidly multiply and spread to the crab meat, decomposing the amino acids in the crab meat and producing a large number of harmful substances, so eating dead crabs may induce vomiting, abdominal pain and diarrhea.

Avoid eating the four organs of crabs, namely the crab stomach (a triangular bone packet in the center of the inner leading edge of the crab shell), the crab intestine (a black line from the stomach to the umbilicus), the crab heart (commonly known as the hexagonal plate), and the crab gills (the abdomen is two rows of soft things in the shape of eyebrows). Among these 4 organs, bacteria and harmful substances are the most, and they must be removed when eating.

Do not eat with fruits containing tannic acid. Crabs and persimmons are two things that can be eaten in autumn, but they cannot be eaten together. Zhao Xiaochun said that crab meat is rich in protein, and persimmons contain a lot of tannic acid, these two substances will react with each other, forming protein coagulation into a lump, and our stomach is difficult to digest this product. Therefore, if someone eats crab and eats persimmons, there may be nausea, vomiting, abdominal pain, diarrhea and other discomforts.

Avoid strong tea and cold things. Drinking strong tea when eating crab will dilute the gastric juice and cause gastrointestinal discomfort. Autumn pear, chrysanthemum tea are cold food, and cold crabs are eaten together, will damage the spleen and stomach, causing indigestion, spleen and stomach deficiency especially pay attention to; similarly, when eating crabs can not drink ice water, eat ice cream at the same time, otherwise it will lead to diarrhea, gastrointestinal disorders.

Zhao Xiaochun also reminded that eating crabs should be determined according to their physical condition.

People with weak physique, poor spleen and stomach function, and insufficient gastric acid secretion should not eat crabs. Crabs carry some pathogenic bacteria, because each person's digestive ability and immunity are different, and there are differences in the resistance to pathogenic bacteria and viruses. Such people are easily attacked by pathogenic bacteria and show symptoms of discomfort. In addition, some people feel gastrointestinal discomfort after eating crab, which is caused by the difficulty of digesting the protein in it.

People with colds and colds and fevers should not eat crabs. Because the gastrointestinal function of such people is relatively weak at this time, it cannot digest and absorb the high protein in crabs, and it is easy to have gastrointestinal discomfort.

People with allergies and eczema should not eat crabs. People who are allergic to seafood such as shrimp and crab should not eat crab, otherwise it is easy to cause gastrointestinal smooth muscle spasm, angioedema, followed by nausea, vomiting, abdominal pain, diarrhea and other symptoms, and some can also cause urticaria or asthma. In addition, people with skin diseases such as dermatitis, eczema, and ringworm should also eat with caution so as not to induce diseases or aggravate the disease.

People with hyperlipidemia, hypercholesterolemia and biliary diseases should not eat crabs, especially crab yellow and crab paste. Cholecystitis, the formation of gallstones and excessive cholesterol in the body and metabolic disorders have a certain relationship, crabs contain higher cholesterol, the cholesterol content in each 100 grams of crab yellow may be as high as 400 mg, crab paste is similar, eating crabs is easy to make the disease recur or become heavier.

Patients with gout and hyperuricemia should not eat crab. Each 100 grams of crab meat contains 82 mg of purines, gout patients should not eat crabs during acute attacks, especially can not eat crab meat or crab yellow made of soup, soup; patients in the chronic stage of gout and simple hyperuricemia should eat less.

The elderly and infants should not eat crabs. The elderly have a decline in the function of the digestive system organs, the digestive organs of young children are not perfect, and their digestive absorption capacity is not better than that of young adults, so the consumption of crabs should be based on tasting.

Zhao Xiaochun especially reminded that babies before ten months should not eat crabs, because high protein will increase the burden on the liver and kidneys.
