The Claim

Among adults aged 55 to 80 years at high cardiovascular risk, consuming more than three servings of walnuts per week is associated with a 45% lower risk of all-cause mortality over a median follow-up of 4.8 years.

Adults aged 55 to 80 with high cardiovascular risk who eat more than three servings of walnuts per week have a 45% lower risk of dying from any cause over nearly five years compared to those who eat fewer servings.

See the scientific wording

Among adults aged 55 to 80 years at high cardiovascular risk, consuming more than three servings of walnuts per week is associated with a 45% lower risk of all-cause mortality over a median follow-up of 4.8 years, a stronger association than that observed for other nuts.

Why this might work

Eating walnuts regularly releases special fats that calm down harmful body-wide inflammation and help blood vessels work better, which keeps the heart and other organs functioning longer and reduces the chance of death from any cause.
