Dietary modifications including healthy eating constitute one of the first line strategies for prevention and treatment of atherosclerotic cardiovascular diseases (CVD), including atherosclerosis. In this study, we assessed anti-atherogenic effects of a combination of wild rice and phytosterols in low-density lipoprotein receptor knockout (LDL-r-KO) mice. Male LDL-r-KO mice were divided into four groups and fed with: (1) control diet; (2) the control diet containing 60% (w/w) wild rice; (3) the control diet containing 2% (w/w) phytosterols; or (4) the control diet containing both wild rice and phytosterols for 20weeks. All diets were supplemented with 0.06% (w/w) dietary cholesterol. Blood samples, hearts, and feces were collected and used for biochemical and histological examination. Consumption of 60% (w/w) wild rice in combination with 2% (w/w) phytosterols significantly reduced the size and severity of atherosclerotic lesions in the aortic roots as compared to those in the control group. This effect was associated with significant reductions in plasma total, LDL and VLDL cholesterol concentrations as well as an increase in fecal cholesterol excretion. In conclusion, the dietary combination of wild rice and phytosterols prevents atherogenesis in this animal model. Further investigations are needed to understand mechanisms of action and potential clinical outcome of such dietary intervention.
