Precautions for eating crabs

1, which may cause diarrhea. Traditional Chinese medicine believes that crabs are cold and salty, and people with spleen and stomach deficiency are prone to abdominal pain, diarrhea or indigestion after eating. According to modern medicine, crabs are high in protein and difficult to digest. Solution: One capsule at a time, with warm mature vinegar, Jiang Mo and perilla; People with gastrointestinal diseases are not recommended to eat, which may aggravate the condition.

2, may lead to gout. Crabs contain purine and glycine, which will produce too much uric acid in the blood. People with high uric acid may induce gout.

Don't drink tea while eating crabs. Tea will dilute gastric juice, which has bactericidal effect and can kill bacteria carried by crabs. The content of tannic acid in tea is very high. Tannic acid and protein in crab meat can produce tannic acid protein, which is more difficult to digest and may lead to vomiting, abdominal pain, diarrhea and other symptoms.

4. Crabs and persimmons are grams. Because crabs and persimmons belong to the same season, the probability of eating them at the same time is relatively high. Persimmons contain the same tannic acid as tea, and the symptoms after eating are the same as tea. Eating them together is just indigestion, not poisoning.

5, may cause itching all over the body. Crab meat enters the human circulation through the intestinal wall. Macromolecules that are not easily decomposed, such as protein, can induce allergic reactions, such as gastrointestinal smooth muscle spasm, skin itching and even edema.
