Although crabs are delicious, they are cold in nature, and eating too much can easily damage the intestines and stomach. Traditional Chinese medicine believes that seafood is mostly products of severe cold, which can cause injury to the spleen and stomach, causing nausea, vomiting, abdominal pain, diarrhea and other gastrointestinal diseases. People with poor gastrointestinal function should eat less or no seafood.

Wang Yumei, director of the Nutrition Department of Beijing Huaxin Hospital, said that the cholesterol content in crab roe is relatively high. Every 100 grams of crab roe contains 460 mg of cholesterol. However, the human body’s daily cholesterol intake cannot exceed 300 mg, which may cause high blood lipids. , People with coronary heart disease should especially eat less.

As for the specific amount to eat, it depends on the individual's physical constitution and tolerance. Generally speaking, it is more appropriate for adults to eat two or three pieces per meal, and for children, reduce the amount appropriately. In addition, crabs are high-purine foods, which can aggravate the condition of people with weak gastrointestinal function, abdominal pain and diarrhea, high blood uric acid or gout. People with seafood allergies and skin diseases should not eat it.
