The Claim

Walnut consumption is associated with reduced cardiovascular mortality, and this association remains significant among individuals with suboptimal diet quality.

In plain English

People who eat walnuts have a lower risk of dying from heart disease, even if their overall diet is not healthy.

See the scientific wording

The association between walnut consumption and reduced cardiovascular mortality remains significant even among individuals with suboptimal diet quality, suggesting walnuts may provide cardiovascular benefits independent of overall dietary patterns.

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 plaque buildup in arteries and prevents blockages that cause heart attacks and strokes.

    Even if people don’t eat a super healthy diet overall, those who eat walnuts regularly still have a lower risk of dying from heart disease — walnuts seem to help the heart on their own.
