In plain English

People who eat walnuts have a lower risk of dying, even when their overall diet is taken into account.

See the scientific wording

Walnut consumption is associated with reduced mortality risk independent of overall diet quality.

Why this might work

Eating walnuts delivers a type of fat called alpha-linolenic acid into the body. This fat changes how the liver handles cholesterol, lowering bad cholesterol and raising good cholesterol. It also helps the lining of blood vessels relax and function better, which prevents plaque from building up in arteries. As a result, heart attacks and strokes become less likely, leading to longer life.

  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 and had fewer heart-related deaths, even when researchers accounted for how healthy their overall diet was. This suggests walnuts themselves may be helping, not just replacing bad foods.
