One Drink May Help Heart, But Two Is Too Many

Extra glass negates immediate benefits to circulation, Canadian study says

"Our findings point to a slight beneficial effect of one drink -- be it alcohol or red wine -- on the heart and blood vessels, whereas two or more drinks would seem to turn on systems that stress the circulation. If these actions are repeated frequently because of high alcohol consumption, these effects may expose individuals to a higher risk of heart attacks, stroke or chronic high blood pressure," Floras said.
