The body needs about 12 to 15 percent of its calories in the form of protein. Proteins consist of amino acids and are essentials for tissue maintenance and growth. Eight essential amino acids must be obtained from food because the body cannot make them or convert them from nutrients.
Complete protein sources, such as egg, milk and meat products, contain all eight essential amino acids in the necessary proportion.
Incomplete protein sources, such as wheat and other grains, may contain all eight essential amino acids, but not at adequate levels. Combining a variety of plant proteins will supply adequate complete proteins.
