First, it will cause skin allergies.

Crayfish is a kind of high-protein food, but our body has been ingesting too much protein, which will lead to the heterogeneous reaction of protein, which may cause systemic allergy and red rubella.

Second, it leads to gout.

Don't drink beer when eating crayfish, because lobster has high protein and high purine content. If you drink a lot of beer while eating lobster, it will easily lead to an increase in blood uric acid and gout attacks.

Third, there is rhabdomyolysis.

Generally speaking, crayfish and crabs all carry paragonimiasis, and roasting, frying and pickling can't kill the larvae of paragonimiasis, so it is easy to invade the body when eating, causing rhabdomyolysis and bringing harm to the body.

Fourth, chronic poisoning occurs.

Heavy metals in crayfish exceed the standard, and some heavy metals can remain in the brain and internal organs, causing permanent damage to the liver and kidneys. If we often eat foods with excessive heavy metals, chronic diseases such as blood system diseases and nervous system diseases will appear, and even serious diseases such as acute renal failure will be life-threatening.

Fifth, there is acute gastroenteritis. If you don't eat immature or unclean crayfish, especially acute gastroenteritis. Especially for people with weak stomach, if they eat unclean food, their stomach will be particularly sensitive, and symptoms of acute gastroenteritis such as diarrhea will appear.
