French Reds May Provide More Heart-Healthy Benefits - WebMD Medical News
"A new study shows there may be a good reason why some French red wines are better than others at providing healthy benefits for your heart...
Although many studies have suggested that moderate consumption of wine can lower your risk of heart disease, relatively little is known about what exactly is behind these benefits or why certain wines might be "healthier" than other types of wine or alcoholic beverages."
"... Feb. 5 issue of the Journal of the American College of Cardiology...
German researchers grew cells in the lab from human umbilical cords and soaked them in solutions of six French red wines, three German red wines, pure alcohol (ethanol -- rubbing alcohol), or nothing at all and analyzed how the cells responded.
They found that some of the wines were able to increase both the amount and activity of an enzyme that helps protect blood vessels from hardening (atherosclerosis), a process that can lead to high blood pressure and heart disease. This enzyme, called endothelial nitric oxide synthase (eNOS), increases levels of nitric oxide, which helps lower blood pressure and slow plaque formation among other benefits."
"Some French red wines had as much as quadruple the amount of the enzyme compared to the teetotaler cells, and the German wines had only a modest effect."
"Although pouring wine into a test tube with cells bears little resemblance to sipping a well-aged Bordeaux at dinner, researchers say their findings shed light on the results of several studies that have shown that the French have lower rates of heart disease despite their love of high-fat foods."
