summary

Seafood is a popular delicious food, but some people will have skin redness, itching, peeling and other allergic phenomena when eating seafood. So how to eat seafood allergy? Let's take a look at the methods to prevent seafood allergy.

What symptom does seafood poisoning have

First, eating seafood is easy to cause related diseases, because excessive histamine in seafood will cause physical discomfort. A few people are born with a lack of enzymes to decompose histamine. Eating fresh fish or seafood will cause allergies. Some parts of the body (face, legs, arms, and even the whole body) have pimples and itching symptoms.

Second, the reason for seafood allergy is that seafood is rich in a large number of heterologous proteins, which directly or indirectly activate immune cells, causing the release of chemical media, and then produce a series of complex biochemical reactions. Antibody antigen interaction, the human body will show allergic symptoms.

Third: people often have a special poisoning after eating seafood, which is similar to allergic symptoms, such as skin itching, redness, edema and so on. However, these people may only be sensitive to certain fish. If there is no allergic reaction to seafood under subcutaneous test or monitoring, you can still eat alternative fish or seafood without rejecting all seafood.

matters needing attention

1. For people with poor intestinal immunity, seafood is potentially fatal. We must be careful when we eat seafood such as "drunk crab", "raw sea urchin" and "pickled seafood with soy sauce" without heating. We should also ensure the freshness and hygiene of salmon when we eat it. 2. Every meal to eat a certain amount of seafood, slowly try to increase the amount, once there is an allergic reaction, immediately curb eating. So after several attempts to find their own appropriate amount, each time you eat, you will not be allergic. 3. You'd better not drink beer when you eat seafood. Shrimp, crab and other aquatic products will form uric acid after metabolism, and excessive uric acid will lead to gout, renal tuberculosis and other diseases. If a large number of seafood at the same time, drinking beer, will speed up the formation of uric acid in the body, allergic effect on the body. 4. Fish, shrimp, crab and other aquatic products are rich in protein, calcium and other nutrients. Fruits contain more tannic acid. If you eat fruits immediately after eating aquatic products, it will not only affect the human body's reception of protein. Calcium in seafood will combine with tannic acid in fruits to form insoluble calcium, which will affect intestinal health and cause abdominal pain, nausea, vomiting and other symptoms. It's best to eat more than 2 hours apart. The fruits with more tannic acid are persimmon, grape, pomegranate, hawthorn, green fruit, etc.
