It is reported that100g of Portunus trituberculatus crab meat contains protein14g and 2.6g of fat, and it has the effect of promoting blood circulation and removing blood stasis.

Dai Furen, deputy director of the nutrition clinic of the Municipal People's Hospital, reminded that although crab meat is good in nutrition, it must be noted when eating it. Portunus is cold, people who have allergic history to crabs, or people with urticaria, allergic asthma and allergic dermatitis, especially children, the elderly and pregnant women with allergic constitution, it is best not to eat crabs. Besides, crabs contain a lot of protein and high cholesterol, so you can't eat too much at a time.

Qiu Huasheng, director of the Primary Aquatic Products Quality and Safety Office of the Municipal Marine Fisheries Bureau, said that many citizens like to eat drunken crabs, but it is best for the citizens to make their own, because pickled crabs and drunken crabs that fail to meet the hygiene standards are likely to infect paragonimiasis, so it is better to buy drunken crabs made by regular food companies.
