Crab is a highly sensitive food and is called "Mao" by the people. For people with allergies, eating crabs can induce and aggravate allergic reactions, causing gastrointestinal smooth muscle spasm, angioedema, rash, asthma, and even anaphylactic shock in severe cases.

Experts remind: people with allergic history or urticaria, allergic asthma and allergic dermatitis, especially children, the elderly, pregnant women and other allergic people, had better not eat crabs.

Patients with cholecystitis, hepatitis, acute and chronic pancreatitis, and severe cardiovascular and cerebrovascular diseases should eat as little as possible or not, and wine should not be accompanied by crabs.

People with diarrhea, stomachache, cold, fever or spleen and stomach deficiency should not eat crabs, because crabs are cold foods, which are not easy to digest and will aggravate spleen and stomach discomfort.

Pregnant women with weak constitution are not suitable for eating crabs.
