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.
