Pork, the meat with the most iron supplement.

There is a big difference between fat and lean pork. Fat is high in fat and low in protein. Eating too much can easily lead to diseases such as hyperlipidemia and obesity. Most of protein is concentrated in lean meat, which also contains hemoglobin, which can supplement iron and prevent anemia.

Hemoglobin in meat is better absorbed than that in plants, so eating lean meat to supplement iron is better than eating vegetables. Because pork has soft fibrous tissue and contains a lot of intramuscular fat, it is better to digest and absorb than beef.
