Beef
There are up to 8 amino acids in beef, including leucine, lysine, and valine. These components play an important role in the synthesis of muscle protein. Depending on the cut, calorie content can vary. The body can digest lean minced beef more easily than fatty steaks. This means that amino acids from the food would enter your bloodstream sooner. Nevertheless, studies have not shown that this could lead to a difference in the synthesis of muscle protein. In addition, beef contains a lot of zinc and iron.[3]
