1. Is crab a cold food? Chinese medicine believes that crabs belong to cold food. Traditional Chinese medicine has a long history of understanding the medicinal value of crabs. According to Fukang Fang, "it can replenish bone marrow, nourish liver yin, replenish gastric juice, strengthen bones and muscles, promote blood circulation and treat gangrene". The Dictionary of Modern Chinese Medicine says that its functions are: "clearing away heat, promoting blood circulation, healing sores, treating bone and muscle injuries, scabies, lacquer sores and burns". _ As we all know, crabs are delicious, and this delicacy comes from the nutritional value of crabs. In the edible part of crab, every 100g contains 80g of water, protein 14g, 22g of fat, 0.7g of carbohydrate, 0. 14 1g of calcium and 0. 19 1g of phosphorus. Muscle contains 10 kinds of free amino acids, among which glutamic acid, proline and arginine are more abundant. 2. What should I pay attention to when eating crabs? 1, no tea. Avoid drinking water when eating crabs and within 1 hour after eating crabs. First, tea will dilute gastric juice, which is not conducive to crab digestion; Secondly, tannic acid in tea will solidify protein in crab meat. These two reasons are not conducive to the digestion and absorption of crabs, and may also cause abdominal pain and diarrhea. 2, can not eat with persimmons. In autumn, crabs are fat and persimmons are ripe, but you can't mix them. Because tannic acid and other ingredients in persimmon will coagulate crab meat protein, the coagulated substance will ferment and rot if left in the intestine for a long time, causing vomiting, abdominal pain, diarrhea and other reactions. Crabs and persimmons are cold, and eating the same cold will damage the spleen and stomach. It is best not to eat crabs with grapes, pomegranates, hawthorn, pears and apples.
