Higher baseline blood levels of long-chain n-3 polyunsaturated fatty acids (EPA, DHA, DPA) are associated with a significantly reduced risk of sudden cardiac death in men without prior cardiovascular disease.

Maintaining higher blood levels of long-chain n-3 fatty acids (found in fatty fish) is associated with a significantly lower risk of sudden cardiac death, even in men with no prior heart disease. This suggests that regular consumption of fish or appropriate supplementation may be a valuable preventive strategy for cardiovascular longevity.

GoodSupportsHIGH confidence

Why this rating

Prospective nested case-control design with long follow-up (17 years) and rigorous adjustment for confounders, but not a randomized controlled trial of the nutrient itself.
