28 Aug 2019 --- Diets high in plant-based protein may contribute to a longer life, according to a study published in Jama Internal Medicine. The study – carried out by the Japan Public Health Center–based Prospective Study Group – followed 70,696 Japanese adults for almost 20 years, during which 12,381 of the participants died. Based on data collected in questionnaires, researchers found that higher plant protein intake was associated with lower rates of mortality. However, there was no clear association between mortality and animal protein intake. These findings support consumers’ growing interest in plant-based proteins for a healthier lifestyle and a more sustainable planet.
