Taboos for eating crabs:

1. Crabs should not be eaten with fruits

The main component of crab meat is protein. Also contains calcium, phosphorus, iron and vitamin A, etc. Therefore it is not only delicious but also nutritious. However, if eaten with fruits, it will easily combine with the tannic acid contained in the fruits to form tannic acid protein, which is not easy to digest, increases the burden on the gastrointestinal tract, and may cause symptoms such as diarrhea. Therefore, do not eat fruits immediately after eating crabs, especially fruits with high tannic acid content such as persimmons.

2. Crab should not be eaten with yogurt.

Crab is a cold food and can easily cause diarrhea. Yogurt is rich in lactobacilli, which can speed up gastrointestinal motility. Therefore, eating yogurt and crab at the same time is more likely to cause diarrhea, especially for people with weak spleen and stomach.

3. Avoid eating crabs with beer

Many people like to drink beer when eating crabs, which is likely to cause gout attacks. Crab is a high-purine food. The end product of purine metabolism in the human body, uric acid, can aggravate gout. Therefore, patients with abnormal purine metabolism or gout must eat crabs with caution.

4. Avoid eating dead crabs and undercooked crabs

Do not eat dead crabs and undercooked crabs. Live crabs must be steamed and cooked thoroughly. Live crabs can excrete bacteria in the body through metabolism. Once a crab dies, bacteria in the body will multiply and decompose the crab meat. Some bacteria will also produce toxins, causing food poisoning.
