The Claim

An increase of 0.5 serving (28 g) per day of walnut consumption is associated with a 14% lower risk of death from cardiovascular disease among U.S. adults aged 60 and older, independent of overall diet quality and other lifestyle factors.

In plain English

U.S. adults aged 60 and older who eat an additional 28 grams of walnuts per day have a 14% lower risk of dying from cardiovascular disease, even when accounting for their overall diet and other lifestyle habits.

See the scientific wording

Higher walnut consumption is associated with a 14% lower risk of death from cardiovascular disease per 0.5 serving (28 g) increase per day in U.S. adults aged 60 and older, independent of overall diet quality and other lifestyle factors, suggesting a potential role for walnuts in reducing cardiovascular mortality.

Why this might work

Eating walnuts delivers a type of fat called ALA into the body, which changes the balance of fats in the blood and helps blood vessels relax and function better. This reduces the buildup of plaque in arteries and lowers the chance of heart attacks and strokes.

  1. Study: Association of Walnut Consumption with Total and Cause-Specific Mortality and Life Expectancy in U.S. Adults

    People who ate a little more walnut every day—about half a handful—were less likely to die from heart disease, even when scientists accounted for how healthy they were overall. The more walnuts they ate, the lower their risk.
