The Claim

Each additional 3% of daily energy intake from plant protein is associated with a 5% reduction in all-cause mortality risk, indicating a linear dose-response relationship.

In plain English

For every 3% increase in daily calories from plant protein, the risk of dying from any cause decreases by 5%.

See the scientific wording

Each additional 3% of daily energy from plant protein is associated with a 5% reduction in all-cause mortality risk, demonstrating a quantifiable, linear dose-response relationship that supports the public health recommendation to increase plant protein intake as a simple dietary modification for longevity.

Why this might work

Eating more plant protein lowers harmful substances in the blood, reduces inflammation and cell damage, and decreases a growth signal that speeds up aging and cancer. This slows down the damage that leads to heart disease, cancer, and death.

  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

    This study found that if you replace a little bit of your daily food calories with plant-based proteins like beans or nuts, you’re 5% less likely to die from any cause — and that small change adds up over time.
