Dietary protein quality
evaluation in human
nutrition

As the world’s population increases rapidly and against the constraints of limiting land,
water and food resources, it is more important than ever to be able to define accurately
the amount and quality of protein required to meet human nutritional needs and describe
appropriately the protein supplied by food ingredients, whole foods, sole-source foods
and mixed diets. The match between dietary supply and human protein needs is vital to
support the health and well-being of human populations.
