In plain English

People who eat walnuts at least once a week have a 19% lower risk of cardiovascular disease and a 21% lower risk of coronary heart disease compared to those who eat them less often.

See the scientific wording

Consuming walnuts one or more times per week is associated with a 19% lower risk of cardiovascular disease and a 21% lower risk of coronary heart disease, suggesting that walnuts may have a particularly strong association with cardiovascular protection among tree nuts.

Why this might work

Eating walnuts delivers special fats and plant compounds that lower bad cholesterol, raise good cholesterol, and calm inflammation in blood vessels. This keeps artery walls smooth and flexible, preventing plaque buildup that causes heart attacks and strokes.
