In a study of men with high cholesterol, a combination of a Mediterranean-style diet and the drug simvastatin (Zocor) was more effective at lowering cholesterol than either approach alone. The diet also counteracted some of the detrimental effects of the drug, researchers report. Based on the findings, the study's authors say that the importance of a healthy diet needs to be emphasized to patients taking statins. "The findings of our study emphasize the importance of diet as an integral part in the treatment of elevated serum cholesterol," the study's lead author, Dr. Antti Jula of the Research and Development Center of the Social Insurance Institution in Turku, Finland, told Reuters Health. Study after study has shown that statins decrease the risk of heart attack. Besides lowering levels of triglycerides and LDL, the "bad" form of cholesterol, statins boost HDL, the "good" cholesterol. A Mediterranean-style diet is rich in fruits, vegetables, grains and nuts. It includes few saturated fats, but plenty of healthier fatty acids like the ones found in olive oil. This diet has also been shown to reduce the risk of heart disease. Lowering cholesterol and the accompanying risk of heart disease does not need to be an either/or decision, according to a report in the February 6th issue of The Journal of the American Medical Association. Jula's team compared the two cholesterol-lowering approaches in 120 men with untreated high cholesterol. During the first 4 to 6 weeks of the study, the men were randomly assigned to adopt a Mediterranean diet or to continue their normal diet. Then half of the men in each group were randomly assigned to take simvastatin each day. The remaining men in each group took a placebo, which did not contain any medication. After 12 weeks, the men taking simvastatin switched to the placebo and vice versa. Both diet and drug therapy provided benefits on their own, and these effects added to each other when used in combination, the researchers report. "Our study shows that a proper diet will give additional benefits to the statin treatment," Jula told Reuters Health. Both approaches lowered total cholesterol and LDL, with simvastatin lowering levels about three times as much. But the cholesterol-lowering drug reduced levels of three important antioxidants--vitamin E, beta-carotene and ubiquinol--by 16% to 22%. The health consequences of the decline in these antioxidants is not known and needs to be evaluated in long-term studies, Jula pointed out. In contrast to statin therapy, the Mediterranean diet only caused a slight decrease in vitamin E levels. Another benefit of a Mediterranean diet, according to Jula, is that it may counteract statins' potentially harmful effects on the sugar-regulating hormone insulin. Unlike simvastatin, which boosted levels of insulin in the blood, the healthier diet lowered insulin levels.
