"The aim of this study was to characterize the sociodemographic drivers of plant-based protein diet consumption, and to study these in relation to diet quality and cost."
High intakes of plant-based diets were associated with significantly higher diet quality, with minimal impact on higher diet costs. Authors conclude that "plant-based protein diets may be a cost-effective way to improve diet quality at all levels of income."
