Known best as the substance in turmeric that gives the curry spice its characteristic yellow color, curcumin has been found by previous studies to exert antioxidant, anti-inflammation, anticancer, and lipid-lowering effects. Min Young Um , from Korea Food Research Institute (Korea) , and colleagues employed a lab animal model of high cholesterol (hypercholesteremia) to investigate the mechanism by which curcumin impacts parameters of heart health. Rabbits fed a high-cholesterol supplemented with curcumin for 8 weeks had smaller atherosclerotic lesions and less neointimal thickening in the aorta, as compared to those animals fed the high-cholesterol diet without curcumin supplementation. The study authors write that: “Our results demonstrate that curcumin exerts an antiatherosclerotic effect, which is mediated by multiple mechanisms that include lowering serum lipids and oxidized low-density lipoprotein, thus modulating the proinflammatory cytokine levels and altering adhesion molecules and MMP gene expression.”
