 The exclusion of digestibility is a point of misunderstanding and leads to misrepresentation of the meaning of a high or low BV

BV provides a good measure of the usability of proteins in a diet and also plays a valuable role in detection of some metabolic diseases.BV is, however, a scientific variable determined under very strict and unnatural conditions.It is not a test designed to evaluate the usability of proteins whilst an organism is in everyday life — indeed the BV of a diet will vary greatly depending on age, weight, health, sex, recent diet, current metabolism, etc.
