There is no food conflict between crabs, and food conflict does not exist. Cheng Yiyong, chairman of the Chinese Nutrition Society, believes that most of the claims that foods are mutually exclusive have no scientific basis and are spread by rumors.

Cheng Yiyong analyzed that one possibility is that people misunderstood some traditional medicine in the past. The scientific conditions at that time were not developed enough, and the observation of the causes was not precise and systematic enough. For example, crab is a food rich in protein that is prone to spoilage and can easily cause allergies in the human body. After some people ate leeks and crabs, they developed vomiting and diarrhea or food allergy symptoms because the crabs were slightly deteriorated. However, doctors at the time could speculate on the incompatibility of the foods. After all, it was not possible to detect microorganisms, allergens, etc. at that time, and it would be mistaken for food to be incompatible with each other.

Taboos for eating crabs:

1. People with allergies should not eat them. Histamine produced by bacterial decarboxylation of histidine in crab is an allergenic substance that can easily induce allergic symptoms. People with a history of food allergies, protein allergies, and asthma should not eat hairy crabs.

2. People with colds and fever should not eat it. The Qing Dynasty's food nutrition treatise "Suixiju Diet Manual" records that crabs are contraindicated if eating too much causes wind, cold, unclear seasonal sensation, phlegm, cough and diarrhea. People with colds, fever, and diarrhea should eat a light diet. High-protein crabs are not easy to digest and absorb. Eating crabs may make it difficult to recover from a cold or worsen the condition.

3. Gout patients should not eat it. Crab is a high-purine food, and uric acid, the end product of purine metabolism in the human body, can aggravate the condition of gout patients. Patients with abnormal purine metabolism or gout must stay away from crabs, let alone try the "gout package" of "crab + beer".
