One of the most nutritious foods, beef has appetite-sating high-quality protein, which has all the essential amino acids needed (isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine and more)to build muscle and bone. Beef is a great source of B vitamins (vital for brain function), and the most absorbable form of iron (called haem iron), which builds red blood cells and gives you energy. Its rich store of zinc supports the immune system.
Beef contains both saturated and monounsaturated fat (thought to be protective against heart disease). Contrary to the prevalent dogma, it’s emerging that there is no good evidence to support the notion that saturated fat is harmful. Beef from grass-fed cattle is a great source of omega 3 fatty acids, and conjugated linoleic acid, which some studies show reduces the risk of cancer, obesity, diabetes and some immune system disorders.
