2 Symptoms of seafood allergy People often have a special poisoning after eating seafood, which is manifested as allergic symptoms such as itchy skin, redness and edema. However, these people may only be sensitive to certain fish. If you do subcutaneous experiments or monitor that there is no allergic reaction to eating seafood, you can still eat alternative fish or seafood without rejecting all seafood.
If you eat stale or rotten green skin red meat fish, it can cause poisoning; Pickled salted fish, if the raw materials are not fresh or pickled, contain more histamine, which can also cause poisoning after eating. People with allergies may also have poisoning symptoms if they eat a small amount of histamine.
Poisoning occurs quickly, often at 0.5~ 1 hour after eating, sometimes as long as 5 minutes, and for a long time as long as 4 hours. Symptoms at onset are mild, and recovery is quick, often manifested as blushing, dizziness, headache, heartbeat, palpitation, chest tightness, shortness of breath, swelling of face and lips, numbness of tongue and limbs, nausea, vomiting, itching of skin, etc.
3 What should I do if I am allergic to eating seafood 1? For people with poor intestinal immunity, eating seafood is potentially fatal. Be careful when eating unheated seafood such as "drunken crab", "raw sea urchin" and "marinated seafood in soy sauce", and ensure the freshness and hygiene of the fish when eating salmon.
2, eat a certain amount of seafood every meal, slowly try to increase the amount, once there is an allergic reaction, immediately curb eating. So after several attempts, I found my proper amount, and every time I ate, I wouldn't be allergic.
3. It is best not to drink beer when eating seafood. Aquatic products such as shrimp and crab will form uric acid after metabolism, and excessive uric acid will lead to gout, renal tuberculosis and other diseases. If you eat a lot of seafood and drink beer at the same time, it will accelerate the formation of uric acid in the body and have an allergic effect on the body.
4. Aquatic products such as fish, shrimp and crab are rich in nutrients such as protein and calcium. Fruit contains more tannic acid. If you eat fruit immediately after eating aquatic products, it will not only affect the human body's acceptance of protein, but also the calcium in seafood will combine with tannic acid in fruit to form insoluble calcium, which will affect the intestinal health and cause abdominal pain, nausea, vomiting and other symptoms. It is best to eat more than 2 hours apart. Fruits containing more tannic acid include persimmon, grape, pomegranate, hawthorn and olive.
5. The principle of not drinking tea after eating seafood is similar to that of not eating fruit. Because tea also contains tannic acid, it can also form insoluble calcium with calcium in seafood. Drinking tea before or after eating seafood will increase the opportunity of combining calcium with tannic acid. Therefore, it is best not to drink tea when eating seafood. In the same way, it is best to have an interval of more than 2 hours.
6. Any seafood can only be made into steamed and boiled dishes in a highly fresh state. Therefore, eating seafood must be fresh.
7, in addition to eating seafood, it is best to freeze first and then pour some light salt water. Eat more vinegar and chew slowly, so that the enzymes in saliva can slow down the reception of allergens in the gastrointestinal tract.
