Why You Need Protein in Your Diet

Protein is an essential nutrient found in animal products, nuts, and beans. The name protein name comes from the Greek word protos, which means “first.” Your body uses proteins in your diet to build new cells, maintain tissues, and synthesize new proteins that make it possible for you to perform basic bodily functions. Your ability to see, think, hear, and move — in fact, to do just about everything that you consider part of a healthy life — requires your nerve cells to send messages back and forth to each other and to other specialized kinds of cells, such as muscle cells. Sending these messages requires chemicals called neurotransmitters. Making neurotransmitters requires — guess what — proteins.
