2. It is best to eat no more than two at a time. Crabs are nutritious and delicious, but they are cold in nature and high in protein, which easily irritates the gastrointestinal tract. Therefore, everyone should not eat more than three crabs per meal, otherwise it will easily cause vomiting, diarrhea and other symptoms.
Before eating crabs, be sure to clean them, because crabs like to live in polluted waters and are addicted to animal carcasses. Their bodies are contaminated with dirt, and the gastrointestinal tract is a place to hide dirt and accept dirt, which inevitably contains poisons and germs. Before cooking, clean the crab body surface with a brush, and it is best to soak it in light salt water for a while, and then put it into a steamer or pot for full steaming. When eating crabs, remove the stomach, gills, intestines and heart of crabs. They are all unclean things. If the cooked crab can't be eaten at one time, it should be heated next time, not eaten cold. It is best not to drink tea when eating crabs and within 1 hour after eating crabs. Because boiling water will dilute gastric acid, tea leaves will solidify some components of crabs, which is not conducive to digestion and absorption, and may also cause abdominal pain and diarrhea. When crabs are fattened, persimmons will be ripe. Don't eat these two at the same time. Because tannic acid and other ingredients in persimmon will coagulate protein in crab meat, the coagulated substances will ferment and rot in the intestine for a long time, causing nausea, vomiting, abdominal pain, diarrhea and possibly lithiasis.
