Seafood Allergy. Causes, Symptoms, Treatment

seafood allergies

Nowadays, more and more people prefer seafood to meat because it is rich in omega-3 fatty acids, useful nutrients, and protein. However, despite its exceptional health benefit, it may trigger an allergic reaction in people.

Nevertheless, it is worth mentioning that being allergic to seafood doesn’t mean that all its types are unsafe for you, you may be allergic to certain varieties. Thus, people, who don’t consume crustaceans or mollusks can eat cartilaginous fish and vice versa.

What Are the Allergens?

Basically, muscle protein tropomyosin is responsible for the allergic reaction, crustaceans (shrimp, crayfish, lobster, crab) and mollusks (scallops, octopus, oysters, snails, clams, squid) contain it. Also, parvalbumin, which is found in fish, also may trigger the allergy. On top of that, another allergen is arginine kinase, it is found in tiger shrimp and white shrimp.

So, when the body identifies one of these allergens, it releases histamine and other chemicals to fight the alien. Eventually, mild or even life – threatening symptoms develop.

Many people also wonder if fish oil supplements are a health hazard. These supplements undergo many levels of purification, which remove protein, so usually, they are safe. However, it is recommended to go for other supplements, which give necessary fatty acids or rule out reactions to fish oil supplements.

  1. During the manufacturing (production and packaging equipment).
  2. At retail (shared tools).
  3. During the preparation (the same cutlery, hands).

So, each person with a seafood allergy should be very careful about what he eats and where he consumes food so that not to suffer from allergy symptoms.
