The Claim

In adults aged 55 to 80 years at high cardiovascular risk, consuming more than three servings of nuts per week is associated with a 39% lower risk of all-cause mortality over a median follow-up of 4.8 years, independent of dietary patterns, smoking, physical activity, and other cardiovascular risk factors.

In plain English

Adults aged 55 to 80 with high cardiovascular risk who eat more than three servings of nuts per week have a 39% lower risk of dying from any cause over about 4.8 years, compared to those who eat fewer servings, after accounting for diet, smoking, physical activity, and other risk factors.

See the scientific wording

In adults aged 55 to 80 years at high cardiovascular risk, consuming more than three servings of nuts per week is associated with a 39% lower risk of all-cause mortality over a median follow-up of 4.8 years, independent of dietary patterns, smoking, physical activity, and other cardiovascular risk factors.

Why this might work

Eating nuts regularly lowers harmful inflammation and damage from unstable molecules in the blood, which keeps blood vessels healthy and prevents cells from breaking down too quickly, leading to longer life.

  1. Study: Frequency of nut consumption and mortality risk in the PREDIMED nutrition intervention trial

    In older adults at high risk for heart disease, eating more than three handfuls of nuts a week was linked to a 39% lower chance of dying over nearly five years — even when accounting for other healthy habits like not smoking or exercising.
