(Reuters) - One or two alcoholic drinks a day can help healthy people-and heart patients-live longer, new research confirms.But the two new studies-one of nearly 250,000 US adults, the other an analysis of eight previous studies of more than 16,000 people with heart disease and other problems related to clogged arteries-also show that drinkers who exceeded recommended limits for alcohol consumption saw no heart health benefits. "No question, heavy or binge drinking can have adverse health outcomes," Dr. Simona Costanzo and colleagues from Catholic University in Campobasso, Italy, warn in their report.
