Protein Bioavailability and Quality Protein
bioavailability means how well the body is able to utilize and digest it.
Protein digestibility-corrected amino acid score (PDCAAS) is a score that explains the quality of the protein based on the amino acid profile. It is the most widely used and trusted method to check protein quality. Protein items can contain complete protein. But, due to digestibility factors, it can still have PDCAAS<1. Egg, whey protein, milk have PDCAA scores equal to 1.
Animal-based
protein sources have a higher concentration of essential amino acids. Whereas,
Plant-based
sources have lower protein quality. The digestibility of plant-based protein (except soy) appears to be less than that of animal products, indicating that vegans may benefit from higher protein intake than the meat-eaters. Various plant-based protein sources can be combined to achieve high-quality protein feedings.
