Walnuts, due to their high alpha-linolenic acid (ALA) content, provide anti-arrhythmic protection against sudden cardiac death and coronary heart disease.
Include walnuts in your diet to increase alpha-linolenic acid (ALA) intake. This plant-based n-3 fatty acid helps protect against sudden cardiac death and coronary heart disease through anti-arrhythmic effects, offering a benefit comparable to marine n-3s.
GoodSupportsHIGH confidence
N-3 PUFA from nuts, mainly ALA in walnuts, protect from fatal coronary heart disease and sudden death due to their anti-arrhythmic properties.
Why this rating
Supported by observational studies and secondary prevention trials (Lyon Diet Heart Study).
