Description: Pigs are also called tapirs, dolphins and Taoziqian. Because it is simple to raise and has the characteristics of less bone and lean meat, it is one of the most eaten meats in daily life. Physicians of past dynasties thought: "pigs are used the most, but meat should not be eaten more, which makes people fat and is also caused by muscle deficiency." "Where meat is supplemented, pork is not supplemented." "Meat tonifies yin, which is fire to help water. When the meat is covered, it will be damp and hot, and the heat will produce phlegm. Phlegm is born, qi does not fall, and various diseases are carried out. " Therefore, it is useless for patients with yin deficiency and blood deficiency to eat more pork. However, it is reported that a professor at Ryukyu University in Japan found through investigation that pork can also become a "longevity medicine" if cooked properly. The survey results show that the elderly over 80 years old in a certain place eat pork almost every day, mainly because of different cooking methods and long cooking time. Boil pork for two or three hours first, then add kelp or radish and cook for another hour to make soup. According to laboratory analysis, after long-term stewing of pork, the fat will decrease by 30-50%, the unsaturated fatty acid will increase, and the cholesterol content will be greatly reduced. Although pork is a daily food, ordinary healthy people and people with diseases can eat it, but eating too much will make people fat and cause wind phlegm. Eating too much or eating cold food will easily cause flatulence, bloating and diarrhea. For fat meat and lard, people with high blood pressure or hemiplegia (stroke) and people with insufficient stomach, fat deficiency, excessive phlegm and dampness, and indigestion should use it with caution or eat less. Generally all medicines are lean pork.
