The "PROS" for Protein

Known mostly for their muscles building properties, Proteins are also responsible for the production of hormones and enzymes, supporting immune system functions, and another source of energy for the body. Made from Amino Acids, proteins are bonded together in various orders and shapes to form specific proteins throughout the body. There are 20 different Amino Acids. There are 9 Essential Amino Acids which we must ingest in our daily nutrition. All animal proteins are called Complete Proteins because they contain all of the Essential Amino Acids. Most plant sources of proteins are lacking in one or more of the 9 essential Amino Acids and for this reason are called Incomplete Proteins.
When considering the ingestion of protein, it is important to understand the “All or None Principle”. Simply put, all 9 essential Amino Acids must be present in order for the body to synthesize protein. If even one is absent, no synthesis can occur. This causes the body to “break-down” muscle to produce the protein needed for other bodily functions resulting in the lost of lean muscle mass and a reduction of overall metabolism.
This situation most be taken into special consideration by those on vegetarian diets. Adequate steps must be taken when arranging meals to guarantee the proper mixture of foods with complementary Amino Acids to lessen the possibility of reduction for lean muscle mass.
