In plain English

People who eat walnuts have a lower risk of dying from any cause, even if they already eat a healthy diet.

See the scientific wording

Walnut consumption reduces mortality risk even in individuals with high baseline diet quality.

Why this might work

Eating walnuts delivers a type of fat called ALA into the body, which changes the composition of fats in the blood and improves the lining of blood vessels. This reduces plaque buildup in arteries and allows blood to flow more easily, lowering the chance of heart attacks and strokes that cause death.
