"When it comes to keeping your heart healthy, one drink is good, but two could be too many, say Canadian researchers who studied the effect of alcoholic beverages on blood vessels. In their tests on a group of healthy adults, one drink produced relaxation of the blood vessels, pumping up blood flow. But two made the heart work harder, and also blunted the normal dilation of vessels. As for type of beverage, you can take your pick, the researchers concluded. Though red wine is a reputed heart aid, when it came to this blood vessel boost, it was no more effective than plain ethanol (similar to the kind of alcohol used in cocktails). So raise a glass of white wine, beer, vodka, or other favorite, but stop at one a day. "^^<http://www.w3.org/2001/XMLSchema#string>
