Because adequate protein intake is essential for optimum growth to occur in children, the World Health Organization conducted significant research on protein requirements. What was determined was that not all proteins supply the proper amounts and proportions of amino acids necessary for adequate growth and development. Complete proteins are proteins that contain the essential amino acids in amounts that are sufficient for maintenance of normal growth rate and body weight. Complete proteins are said to have a high biological value. These include proteins contained in eggs, milk, milk products, and most animal proteins.
Incomplete proteins are usually deficient in one or more of the essential amino acids. This amino acid deficiency creates a limiting amino acid condition which will adversely affect growth and development rates. Most plant proteins are incomplete because they are low in an essential amino acid. However, based on the above discussion on the dynamics of amino acids in the body, even high quality proteins may be incomplete for the athlete’s needs. Furthermore, research indicates that the proper proportions of both essential and nonessential amino acids are required for optimum growth and recovery. This means eating high quality protein sources, as well as consuming sports supplement formulations. The dietary goal is to eat a diet fortified with amino acids that are used for energy and non-growth functions and to ensure that there will be an adequate amount of amino acids for growth and recovery without creating too much of an excess intake of protein.
Biological Value as a measurement technique is currently being used to describe the ability of food proteins to deposit nitrogen into muscles.
BV = Nitrogen Retained divided by Nitrogen absorbed X 100
= (dietary N) - (F - Fm) + (U - Ue) divided by (dietary N) + (F - Fm) X 100
Here are some of the "contemporary " BVs of a few of the more common protein sources in our diets:
Soy 74 (Worst)
Egg white 77
Casein 88
Milk 91
Whole egg 100
Raw whey 104
Egg and milk 118.5
Whey and potatoes 134
Engineered Whey Protein 157 (Best)
