Now is the time to promote a new protein measurement method
There is a new method for measuring protein quality. It is more scientifically valid because it more accurately reflects the ability of the body to utilize essential amino acids.
For nearly 20 years, the world had accepted the PDCAAS (Protein Digestibility Corrected Amino Acid Score) as the gold standard for measuring protein quality. The dairy industry has long argued that this method has flaws and limitations.
At the November 2012 meeting of the International Dairy Federation in South Africa, it was announced that the Food and Agriculture Organization of the United Nations (the same group that adopted the PDCAAS method) has now accepted a new method for measuring protein quality. The new Digestible Indispensible Amino Acids Score method (DIAAS) more accurately reflects the quality of dairy proteins and their ability to complement other proteins.
