Risk factors of cardiovascular disease such as lipid aberrations, hypertension, abdominal adiposity and elevations in systemic inflammation, are prominent aetiologies in hyperlipidemia. Supplementation with n-3 PUFA is associated with a reduction in cardiovascular events through its hypotriglyceridemic, anti-aggregatory and anti-inflammatory properties. Plant sterols have potent hypocholesterolemic properties, although their effect on the inflammatory cascade is uncertain. This study investigated the effect of combined supplementation with n-3 PUFA and plant sterols on cardiovascular risk factors, blood pressure, body composition, markers of systemic inflammation and overall risk, in hyperlipidemic individuals.

The study was a 3-week randomised, double-blind, placebo-controlled, 2×2 factorial design, in four parallel groups. Sixty hyperlipidemic participants were randomised to …
