Importance of Protein

Proteins are the building blocks of life. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development in children, teens, and pregnant women.Protein foods are broken down into parts called amino acids during digestion. The human body needs a number of amino acids in large enough amounts to maintain good health.

Amino acids are found in animal sources such as meats, milk, fish, and eggs. They are also found in plant sources such as soy, beans, legumes, nut butters, and some grains (such as wheat germ and quinoa). You do not need to eat animal products to get all the protein you need in your diet. Amino acids are classified into three groups: Essential Nonessential Conditional

Essential amino acids cannot be made by the body, and must be supplied by food. They do not need to be eaten at every meal. The balance over the whole day is more important.

Nonessential amino acids are made by the body from essential amino acids or in the normal breakdown of proteins.

Conditional amino acids are needed in times of illness and stress.
