The Claim

Walnut consumption is associated with reduced all-cause mortality in both men and women, with a stronger association observed at lower intake levels in women.

In plain English

People who eat walnuts have a lower risk of dying from any cause, and this link is stronger in women who eat smaller amounts of walnuts.

See the scientific wording

Walnut consumption is associated with reduced all-cause mortality in both men and women, with a potentially stronger effect at lower intake levels in women.

Why this might work

Eating walnuts delivers a type of fat called alpha-linolenic acid 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, which leads to people living longer.

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

    People who ate walnuts regularly lived longer than those who didn’t, and even eating a small amount once a week helped. Women who ate walnuts seemed to gain a little more life expectancy than men, especially at lower amounts.
