A Complete Protein contains all 9 of the Essential Amino Acids necessary for human health.  Some foods contain all the essential amino acids on their own in a sufficient amount to qualify as a "Complete Protein.” The USFDA has a “Protein Digestibility Corrected Amino Acid Score (PDCAAS) and a perfect score is 1.0.  Certain Dairy products (including whey), Egg Whites, and soy protein isolate earn a PDCAAS score of 1.0.


Other foods, such as Amaranth, Buckwheat, Hempseed, Meat, Poultry, Soybeans, Quinoa, Seafood, and Spirulina also are Complete Protein Foods, though they earn a PDCAAS score of slightly less than 1.0.
