The Claim

Higher intake of plant protein is associated with a 9% lower risk of all-cause mortality, a 12% lower risk of cardiovascular disease mortality, and a 21% lower risk of dementia mortality in postmenopausal women, independent of age, race, lifestyle, and other dietary factors.

In plain English

In postmenopausal women, consuming more plant protein is linked to lower rates of death from all causes, heart disease, and dementia.

See the scientific wording

Higher intake of plant protein is associated with a 9% lower risk of all-cause mortality, an 12% lower risk of cardiovascular disease mortality, and a 21% lower risk of dementia mortality in postmenopausal women, independent of age, race, lifestyle, and other dietary factors, suggesting that replacing animal proteins with plant-based sources may contribute to longer life and reduced risk of chronic disease.

Why this might work

Eating more plant proteins lowers inflammation in the body, which reduces damage to blood vessels and brain cells, leading to fewer heart attacks, strokes, and brain degeneration.

    Women who ate more protein from plants like beans and nuts instead of meat and eggs lived longer and had lower risks of dying from heart disease and dementia, even after accounting for other healthy habits.
