The Claim

Higher intake of plant protein is associated with an 8% lower risk of all-cause mortality and a 12% lower risk of cardiovascular disease mortality, with each additional 3% of daily energy from plant protein associated with a 5% reduction in all-cause mortality risk.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

People who consume more plant protein have a lower risk of dying from any cause or from cardiovascular disease compared to those who consume less plant protein. Each increase of 3% of daily calories from plant protein is linked to a 5% lower risk of death from any cause.

See the scientific wording

Higher intake of plant protein is associated with a 8% lower risk of all-cause mortality and a 12% lower risk of cardiovascular disease mortality, based on pooled data from 13 and 10 prospective cohort studies respectively, with a dose-response relationship showing that each additional 3% of daily energy from plant protein reduces all-cause mortality risk by 5%, suggesting plant-based protein sources may contribute to longevity.

Why this might work

Eating more plant protein lowers bad cholesterol in the blood, reduces harmful substances made by gut bacteria, and decreases a growth signal that promotes aging and cancer. These changes protect the heart, reduce damage to blood vessels, and slow down cellular aging, leading to lower risk of death from heart disease and other causes.

  1. Study: Dietary intake of total, animal, and plant proteins and risk of all cause, cardiovascular, and cancer mortality: systematic review and dose-response meta-analysis of prospective cohort studies

    People who eat more protein from plants like beans and nuts have a lower chance of dying from heart disease or any cause — and even a small increase in plant protein (3% of daily calories) cuts death risk by 5%.
