After eating crabs, wait two hours before eating fruit (crabs are seafood).

Eating seafood and fruits together will cause abdominal pain

Fish, shrimp, crab and other seafood are rich in nutrients such as protein and calcium. Fruits contain a lot of tannic acid. If you eat fruit immediately after eating seafood, it will not only affect the body's absorption of protein, but the calcium in the seafood will also combine with the tannic acid in the fruit to form insoluble calcium. It can cause irritation to the gastrointestinal tract and even cause symptoms such as abdominal pain, nausea, and vomiting. It is best to wait at least 2 hours before eating.

Seafood should not be eaten with other foods:

Eating seafood with beer can cause gout

It is best not to drink beer when eating seafood. Shrimp, crab and other seafood will form uric acid after being metabolized by the human body. Excessive uric acid can cause gout, kidney stones 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. Therefore, when eating a lot of seafood, be sure not to drink beer, otherwise it will have adverse effects on the body.

Taboos for eating seafood:

1. Undercooked seafood contains bacteria

The bacteria in seafood are mainly harmful to Hemolytic Vibrio, etc., are relatively heat-resistant and can only be killed above 80℃. In addition to the bacteria brought by the water, seafood may also contain parasite eggs and bacterial and viral contamination caused by processing.

2. Drinking tea after eating seafood will cause stones

The reason why you should not drink tea after eating seafood is similar to the reason why you should not eat fruits. Because tea also contains tannic acid, it can also form insoluble calcium with the calcium in seafood. Eating seafood before or after eating seafood will increase the chance of calcium combining with tannic acid.
