[单项选择]Study confirms that moderate drinking reduces stroke risk. Similar to the way a drink or two a day protects against heart attacks, moderate alcohol consumption wards off strokes, a new study found.
The study also found that the type of alcohol consumed—beer, wine or liquor-was unimportant. Any of them, or a combination was protective, researchers reported in today’s Journal of the American Medical Association. "No study has shown benefit in recommending alcohol to those who do not drink", cautioned the authors, led by Dr. Ralph L. Sacco of Columbia University College of Physicians and Surgeons in New York. But the new data support the guidelines of the National Stroke Association, which say moderate drinkers may protect themselves from strokes by continuing to consume alcohol, the authors said.

A. it refutes early studies on the protective effect of moderate drinking against heart attacks
