Gallup, which started tracking Americans' alcohol habits more than 80 years ago, says the drop in drinking rates coincides with Americans' growing concerns that even moderate drinking is unhealthy.

A new Gallup survey has found that only 54% of Americans say they drink alcohol — that's lower than at any other point in the past three decades. The poll comes among a growing belief that even moderate drinking is a health risk.

After years of being told that red wine was good for heart health, more Americans appear to be heeding warnings that even moderate alcohol consumption can be unhealthy.
