Diets rich in eicosapentaenoic acid [EPA; 20:5(n-3)] are associated with decreased arterial stiffness, but postprandial effects on vascular function are unknown. We investigated whether an EPA-enriched high-fat meal could improve postprandial vascular function. Seventeen healthy men ingested 2 test meals
