As the weather gets hotter and hotter, the peak season for eating lobster is coming soon. Looking at the rows of food stalls selling lobster, I can’t help but make an appointment with a few friends to drink beer together. , eating lobster was very satisfying, but after eating, not only did I have skin allergy symptoms when I returned home, but I also had diarrhea and diarrhea, which was extremely uncomfortable. What should I do? What should I do if I am allergic to lobster?

1. You may be allergic to eating lobster

Some people will experience symptoms such as local or systemic itching after eating lobster. Some patients question whether their skin is allergic to eating lobster? Experts from Wuxi Dermatology Hospital will tell you. Everyone is different, and there are significant individual differences. You may be allergic to lobster, but not everyone is allergic.

Of course, some people’s understanding of this disease is still superficial. Experts say: Skin allergy is a kind of sensitive skin that is stimulated and causes some degree of discomfort. It can be divided into three types: dry skin, oily skin, and combination skin.

If you find that you have skin allergies after eating lobster, you must also pay attention to the following points.

First, try to avoid exposing your skin to strong sunlight for a long time and to cold, hot, windy and other harsh weather conditions. These climatic conditions can easily make the skin itchy, red and swollen, or aggravate the skin lesions of existing skin diseases. In severe cases, erosion and drainage may occur. Patients with acute skin diseases should pay more attention.

The second point is to eat more soy products and river plants such as lotus seeds, lotus seeds, lotus roots, water chestnuts, and gorgon seeds (chicken head rice). Eat more fresh vegetables and fruits, appropriate amounts of animal organs, lean meat, etc., eat less greasy food, no fish, shrimp and other seafood, drink less alcohol, and eat less irritating food.

The third point is to bathe and wash your face separately. The bath water is too hot and is not suitable for washing your face. The same applies to other skin types, let alone sensitive skin. So be sure to wash them separately.

2. What to do if you are allergic to lobster

If you don’t eat much and the allergy is not serious, you can eat some foods containing vitamin C and some calcium tablets. Can relieve symptoms. Medications include chlorpheniramine or cetirizine.

In severe cases, appropriate anti-allergic drugs can be used for treatment, such as vitamin C, calcium gluconate, prednisone, etc. Generally, a combination of four anti-allergic drugs will have better effects. Try to eat less seafood in the future. If it is convenient, you can do an allergen test to see what substances you are allergic to, so you can take preventive measures.

This is a skin disease and you need to take care of it slowly. Try not to eat high-protein foods, such as seafood, including shrimp, crabs, oysters and other seafood. Try to stay away from alcoholic drinks while you are sick. You must have adequate rest, have a normal schedule, and have a light diet. Once the rhythm of life is disrupted, it is easy to relapse.

3. Rumors about crayfish

1. What exactly is crayfish? Is it a bug?

The real name of crayfish is "Procambarus clarkii", and its scientific name is Procambarus clarkii. It is a genuine freshwater shrimp and is not an insect at all. It is related to lobsters. In taxonomy, they are all "Decapods". Lobsters belong to the family Lobsteridae, Orocrayidae or Crayfish family, while the crayfish we eat belongs to the Crayfish family (so some in northern my country area it is directly called "_脄"). The genetic relationship between them is equivalent to the relationship between humans and monkeys. They are both an "order" but not a "family".

Crayfish are native to the southeastern United States, so they are also called American crayfish. The native place is near the Gulf of Mexico, especially the mouth of the Mississippi River, so it is also called Louisiana crayfish. It is the most edible freshwater lobster species, with annual output accounting for 70-80% of the entire freshwater lobster output.

2. Crayfish live in sewage and eat domestic garbage and animal excrement?

Crayfish are omnivores, and their main food is organic matter at the bottom of the water. Aquatic plants, algae, aquatic insects, and organic debris are all its food. Of course, it also eats small fish, shrimp, shellfish, etc. Living creatures even kill each other when they don't have enough to eat. Precisely because it has a mixed diet, it has strong vitality and can survive in polluted water bodies. But the crayfish in restaurants are basically farmed. For example, the crayfish in Guijie, Beijing, basically come from the breeding farm in Xuyi. In the breeding environment, animal and plant feeds should be fed according to growth needs, such as wheat bran, bean cake, aquatic insect larvae, etc.

If crayfish could really eat all the pollutants, wouldn’t it be much easier to control environmental pollution in China? Why spend so much money on sewage treatment plants, septic tanks and garbage disposal stations?

3. Is the blue color of crayfish caused by heavy metal pollution?

The color on shrimp shells is mainly formed by the combination of chitin and astaxanthin in the carapace. Depending on the content and degree of binding, it can appear red, orange, blue, green, or white. , black and other colors. For example, Australian lobsters are mainly blue. It’s not unusual to see blue crayfish appearing online as “pet blue lobsters” escaping, or as genetic mutations of individual crayfish.

In fact, crayfish are very sensitive to heavy metals. On the one hand, in water bodies with excessive heavy metals, they cannot successfully shed their shells and cannot survive. On the other hand, heavy metals can accumulate. In nature, organisms at the higher end of the food chain accumulate more heavy metals. Crayfish are at the bottom of the food chain. Therefore, under normal breeding conditions, their heavy metal residues generally do not exceed standards. Chen Shunsheng told reporters that they had conducted a preliminary investigation on crayfish on the market and found that the heavy metal cadmium, lead, and mercury content in crayfish currently on the market almost did not exceed the standard. The Hubei Provincial Entry-Exit Inspection and Quarantine Bureau Technical Center has also conducted testing and found that the heavy metal content in crayfish, except for the shrimp line parts, met the standard. Therefore, eating crayfish is less likely to cause heavy metal poisoning.

4. Will eating crayfish cause myolysis?

Before cooking, in order to save time and cost, merchants usually wash crayfish with shrimp washing powder. Many people believe that the strong industrial acid "oxalic acid" in shrimp powder is the main cause of myolysis. Chen Shunsheng told reporters that there is currently very little evidence that eating crayfish causes myolysis. Yun Wuxin, a Ph.D. in food engineering from the Department of Agriculture and Biology at Purdue University, also pointed out that oxalic acid is actually widely present in food, such as spinach. Although oxalic acid itself is corrosive, only consuming large amounts in a short period of time will stimulate the human digestive system and cause symptoms such as vomiting and nausea. However, patients with myolysis currently do not have similar symptoms, which shows that oxalic acid is not the culprit causing myolysis.
