The Claim

Plant protein intake is not significantly associated with cancer mortality, although it is associated with reduced cardiovascular mortality and all-cause mortality, indicating that any protective effects of plant protein are specific to cardiovascular health and not cancer prevention.

In plain English

Eating plant protein is not linked to lower rates of death from cancer, but it is linked to lower rates of death from heart disease and other causes, meaning its protective effect does not extend to cancer.

See the scientific wording

There is no significant association between plant protein intake and cancer mortality, despite its association with reduced cardiovascular and all-cause mortality, suggesting that the protective effects of plant protein may be specific to cardiovascular health rather than cancer prevention.

Why this might work

Eating more plant protein lowers bad cholesterol and reduces inflammation in blood vessels, which prevents heart disease and death from it. It does not change the biological signals that drive cancer growth, so it does not lower cancer deaths.

    Eating more plant protein is linked to living longer and having fewer heart disease deaths, but it doesn’t seem to lower the risk of dying from cancer. So its benefits appear to be mostly for the heart, not cancer prevention.
