Pork is a red meat, the first meat in China, and is very popular among Chinese people worldwide. Compared with the red meat of beef and lamb, the protein content of pork is low, but the fat content is very rich, and overall, the nutrition is slightly lower than that of beef and lamb, but the price is cheap, so it is very popular among the public. Pork is nutritionally dominated by fat, iron, zinc and calcium, which can meet the needs of growth and development. Because of the high fat content of pork, it is recommended that you try to eat lean meat and less fatty meat.
