Protein Quality In Humans

Abstract: A critical assessment of currently used protein quality evaluation methods is given. The material includes: the importance of protein quality; methods used to assess the protein nutritive value (PNV) in humans; and in vitro methodology for assessing PNV. Guidelines are given for assessing the precision and accuracy in estimates of PNV in human studies; the acceptable degree of accuracy and precision in such estimates can then be defined. Task force reports that discuss the validity and potential use of in vitro assays for predicting protein quality for human consumption are given. (wz).
