How to avoid allergies from eating crayfish

1. It is best to freeze it first and then pour some light salt water. Dip it in more vinegar when eating and chew slowly. The enzymes in saliva can slow down the absorption of allergens in the gastrointestinal tract.

2. For people with poor intestinal immune function, do not be greedy for fresh food and cook it thoroughly before eating.

3. It is not advisable to drink beer when eating crayfish. Drinking large amounts of beer while eating crayfish will produce excessive uric acid, which can form uric acid crystals in the joints and aggravate arthritis symptoms.

4. Crayfish should not be eaten with certain fruits. The calcium in seafood combines with tannic acid to form a new substance that is difficult to digest. Fruits that contain more tannins include persimmons, grapes, pomegranates, hawthorns, green fruits, etc.

5. Do not eat shrimps with vitamin C. Arsenic, which is usually harmless to the human body, can be converted into toxic arsenic under the action of vitamin C.

6. When eating crayfish, be careful not to buy dead crayfish. Also, please note that you should not swim immediately after eating crayfish. You can take Omink when eating crayfish to prevent allergies.
