The Effect of Curcumin on HDL Cholesterol Uptake Capacity in Obese Individuals: A Pilot Study

Abstract

Background and aims: Obesity is a common risk factor associated with cardiovascular disease (CVD) risk. Curcumin has been reported to exert beneficial effects on lipid metabolism, including HDL functionality. We have examined the effects of curcumin on HDL cholesterol uptake capacity in subjects with obesity. Methods: 30 obese individuals received curcumin and placebo 1 g per day for a period of 30 days. The subjects were crossed over to the alternative regimen after a 2 week wash-out period. A modified cholesterol uptake capacity (CUC) assay was used to determine serum HDL functionality.Results: The study groups had similar base line characteristics. We did not find significant effects (p>0.05) of curcumin on serum HDL CUC levels. Conclusion: Curcumin administration at a dose of 1 g per day for 30 days did not affect HDL CUC in subjects with obesity.
