ABSTRACT Plant protein foods contribute ‘ 65% ofthe per
capita supply of protein on a worldwide basis and 32% in the
North American region. These sources of protein are discussed
in relation to their amino acid content, human amino acid re
quirements, and dietary protein quality. Mixtures of plant pro
teins can serve as a complete and well-balanced source of amino
acids for meeting human physiological requirements. This short
review ends with a list of a series of myths and realities con
cerning the relationship between plant protein and human nutri
tion and a list of some nutritional issues of concern to the health professional and informed consumer. Am J C/in Nuir
