The Claim

Substituting 5% of daily energy from animal protein with plant protein is associated with a 14% lower risk of all-cause mortality, a 22% lower risk of cardiovascular disease mortality, and a 19% lower risk of dementia mortality in postmenopausal women.

In plain English

In postmenopausal women, replacing 5% of daily calories from animal protein with plant protein is linked to lower rates of death from all causes, heart disease, and dementia.

See the scientific wording

Substituting 5% of daily energy from animal protein with plant protein is associated with a 14% lower risk of all-cause mortality, a 22% lower risk of cardiovascular disease mortality, and a 19% lower risk of dementia mortality in postmenopausal women, indicating that dietary replacement strategies may be more impactful than absolute intake levels alone.

Why this might work

Replacing animal protein with plant protein lowers inflammation in the blood and makes blood vessels work better, which reduces damage to the heart, brain, and other organs, leading to lower risk of death from heart disease, dementia, and other causes.

    When older women swap a little bit of meat, eggs, or dairy for beans or nuts, they’re less likely to die from heart disease, dementia, or other causes—even if they eat the same total amount of protein. The study shows this swap really helps.
