Biological value (BV) is a measure of the proportion of absorbed protein from a food which becomes incorporated into the proteins of the organism's body. It captures how readily the digested protein can be used in protein synthesis in the cells of the organism.
The PDCAAS considers the global digestibility of the product's protein (a single figure) while the DIAAS accounts for a specific digestibility percentage for each indispensable amino acid The reference values for the PDCAAS are based on a unique age group, the 2 to 5-year-old child which is deemed to be the more demanding.
Whey is the type of protein contained in many popular brands of protein supplements and is preferred by many bodybuilders because of its high biological value (BV) and quick absorption rates. Whey protein also has a bigger effect than casein on insulin levels, triggering about double the amount of insulin release. [69]
The study tested 160 products from 70 top protein powder brands, though neither the products nor brands were named in the report. The sample pool represented 83% of the market, the report read.
The formula for calculating the PDCAAS percentage is: (mg of limiting amino acid in 1 g of test protein / mg of same amino acid in 1 g of reference protein) x fecal true digestibility percentage. [2] The PDCAAS value is different from measuring the quality of protein from the protein efficiency ratio (PER) and the biological value (BV) methods. [3]
