| In a study involving 1,879 Costa Rican adults without diabetes, an increase in daily servings of white rice was positively associated with blood pressure, triglycerides, and fasting glucose, and inversely associated with HDL cholesterol, while an increase in daily servings of beans was inversely associated with diastolic blood pressure. A 35% reduction in risk of the metabolic syndrome was found when one serving of white rice was substituted with one serving of beans. The authors conclude, "Increasing the ratio of beans to white rice, or limiting the intake of white rice by substituting beans, may lower cardiometabolic risk factors." | Reference: | "A higher ratio of beans to white rice is associated with lower cardiometabolic risk factors in Costa Rican adults," Mattei J, Hu FB, et al, Am J Clin Nutr, 2011 Aug 3; [Epub ahead of print].
