Watermelon is cold and rich in various vitamins, while crabs are equally cold. Crabs and watermelons can easily cause gastrointestinal discomfort and diarrhea and abdominal pain, which is a mild food poisoning. Therefore, it is recommended not to eat crabs before and after eating watermelon 1 hour, and vice versa.

The main ingredient of crab meat is protein, and it also contains calcium, phosphorus, iron and vitamin A. Therefore, it is not only delicious, but also nutritious. However, if it is eaten with fruit, it is easy to combine with tannic acid contained in fruit to form tannic acid protein, which is not easy to digest, aggravates gastrointestinal burden, and may cause symptoms such as diarrhea. Therefore, don't eat fruits immediately after eating crabs, especially persimmons and other fruits with high tannins.

Extended data:

1, crabs should not be eaten with yogurt.

Crab is a cold food, which is easy to cause diarrhea, while yogurt is rich in lactic acid bacteria, which can accelerate gastrointestinal peristalsis. Therefore, yogurt and crab are eaten at the same time, especially for people with spleen and stomach deficiency.

2. Crabs should not eat with beer.

Many people love to drink beer when eating crabs, which is likely to cause gout attacks. Crab belongs to high purine food, and uric acid, the metabolic end product of purine in human body, will aggravate gout. Therefore, patients with abnormal purine metabolism or gout must be careful to eat crabs.

3. Avoid eating dead crabs and uncooked crabs.

Don't eat dead crabs and crabs that are not steamed and cooked thoroughly. Live crabs should be steamed and cooked thoroughly. Live crabs can excrete bacteria from their bodies through metabolism. Once the crab dies, the bacteria in the body will multiply and decompose the crab meat, and some bacteria also produce toxins, causing food poisoning.
