Why is eating shrimp allergic?

One reason why people are allergic to shrimp is that shrimp meat contains high content of protein. Similarly, aquatic products, fish with low protein content are less allergic than shellfish.

Allergy to something is hereditary and difficult to solve. Theoretically, any food containing protein may cause allergies.

For the human body, protein contained in shrimp belongs to foreign protein. A foreign protein like this is an antigen for human beings, and like bacteria and viruses, it will be recognized by the immune system as an in vitro antigen, which will immediately trigger a series of immune reactions.

Some people with sensitive constitution are particularly sensitive to different protein, and the immune system often overreacts, which is also commonly known as allergy. Light can cause urticaria, and severe can even lead to shock and death.

Another reason is that some people eat fresh fish and shrimp with excessive histamine because they naturally lack enzymes that decompose histamine, which can cause allergies.

As for the degree of allergy, there are many. What's lighter is that the shrimp is itchy and painful all over the body, and even the hands will break out in a rash when they touch the shrimp.
