Lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) is an emerging independent risk factor for cardiovascular disease (CVD). Lp-PLA(2) can be modified by lipid lowering drugs, but it is unknown whether diet can reduce plasma levels of Lp-PLA(2). The aim of the trial was to study the effect of marine n-3 polyunsaturated fatty acids (PUFA) on plasma Lp-PLA(2) levels in healthy subjects. Sixty healthy subjects were randomized to a moderate dose (2 g) of n-3 PUFA, a high dose (6.6 g) of n-3 PUFA or olive oil (control) daily for 12 weeks. Plasma Lp-PLA(2) was measured at baseline and after the interventions. Plasma Lp-PLA(2) levels were unchanged in all three groups before and after the supplements. Neither did the results differ between groups. There was no correlation between the content of n-3 PUFA in platelets or granulocytes or plasma Lp-PLA(2). Marine n-3 PUFA had no effect on plasma levels of Lp-PLA(2) in healthy adults and relatively young people.
