Consuming More Protein from Plants Associated With Longer Life

Consuming plant-based protein reduces risk of early death from any cause and from heart disease, according to a meta-analysis published in The British Medical Journal. Researchers from Harvard University and Tehran University of Medical Sciences compared animal versus plant-based protein intake and mortality from cancer, cardiovascular disease, and all causes among 32 studies and 715,128 participants. For each additional 3% of calories from plant protein, such as legumes, grains, and soy products, the risk of dying lowers by 5%. Consuming animal proteins did not lower risk of death from heart disease or cancer. The authors suggest replacing animal protein with plant protein for its association with longevity.
