Mounting evidence shows health benefits of grape polyphenols
Date:10/28/2008

wever, a few studies support the disease-preventing benefits of grapes in humans. Studies in patients treated with grape seed extracts have shown improvements in blood flow and cholesterol levels. In other studies, drinking Concord grape juice has improved measures of blood flow in patients with coronary artery disease and lowered blood pressure in patients with hypertension.

Studies investigating the lower rates of heart disease in Francethe so-called "French paradox"first raised the possibility that red wine might have health benefits. The subsequent research reviewed by Drs. Leifert and Abeywardena helps build the case that grapes and grape products might be a useful part of strategies to lower the high rate of death from cardiovascular disease.

At a time of growing interest in the use of "functional foods and nutraceuticals" to promote heart health, grapes and grape polyphenols are "attractive candidates" for use in such supplements, Drs. Leifert and Abeywardena believe. "Therefore," they conclude, "supplementation with grape seed, grape skin or red wine products may be a useful adjunct to consider for a dietary approach in the prevention of cardiovascular diseases, although additional research is required to support such a strategy."
