Anthocyanins in berries exhibited anti-atherogenicity and antiplatelet activities in a metabolic syndrome population

Metabolic syndrome (MetS) is a global challenge for atherosclerosis. It was hypothesized that a four-week consumption of anthocyanin supplements by MetS patients who had three or more risk factors linked with metabolic syndrome would have a greater improvement in cardiometabolic biomarkers and would also reduce the risk of thrombosis. A total of 55 participants in two groups of Normal healthy and MetS (age 25-75y) were given 320 mg anthocyanin supplements twice daily for 4 weeks. Platelet coagulant activities, lipid profiles, fasting blood glucose, and inflammatory and oxidative stress biomarkers were measured before and after supplementation to evaluate the atheroprotective effects of anthocyanins in the study subjects. Four weeks of anthocyanin supplementation significantly decreased cardiometabolic risk factors including the average serum fasting blood glucose (FBG) (by 13.3%, P
