The Claim

Higher dietary intake of plant protein is associated with an 8% lower risk of all-cause mortality and a 13% lower risk of cardiovascular disease mortality in adult populations.

In plain English

Adults who consume more plant protein than animal protein have an 8% lower risk of dying from any cause and a 13% lower risk of dying from cardiovascular disease.

See the scientific wording

Higher dietary intake of plant protein is associated with a 8% lower risk of all-cause mortality and a 13% lower risk of cardiovascular disease mortality in adult populations, based on pooled data from 28 prospective cohort studies involving over 700,000 individuals, suggesting that replacing animal protein with plant protein may contribute to reduced mortality risk, though causation cannot be established due to observational design.

Why this might work

Eating more plant proteins lowers inflammation in the body and makes blood vessels work better, which reduces the chance of heart disease and death from it.

    People who eat more plant-based proteins like beans and nuts tend to live longer and have fewer heart disease deaths, according to a big study of hundreds of thousands of people. But this doesn’t prove eating more plants causes longer life—it just shows they’re linked.
