Pork is a very high source of protein. It contains each of the eight essential amino acids needed to build, repair and maintain body tissue.
Pork is the best dietary source of thiamin and a good source of other B vitamins, including iacin, riboflavin, and vitamins B6 and B12.
Pork is a good source of minerals, particularly iron and zinc. About half of the iron in pork is the most readily absorbed and digested type of dietary iron.
