Just to sustain life, we need daily infusions of top-quality proteins because our bodies cannot store them (or their building blocks, the amino acids) the way they store fats. The proteins we eat may be complete, meaning they contain all the amino acids we need and in the portions necessary to good health. Or they may be incomplete (lacking one or more essential amino acids).

Protein is required for the growth, maintenance,and repair of all body tissues. It is also required for the formation of enzymes and hormones that regulate body processes. Certain proteins transport oxygen, while others facilitate muscle contraction.As antibodies, they are involved in the function of the immune system. Protein can act as an energy source when needed in the fasting state or during extended physical exertion. Many vitamins and minerals are bound to specific protein carriers for transport. Protein is also necessary for blood clotting and fluid balance. In other words, proteins play a vital role in virtually every metabolic, structural, and physiologic process required for life!
