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.

Only 54 percent of American adults say they consume alcohol, according to Gallup, the lowest in the survey’s 90-year history by 1 percentage point.

A new Gallup Poll shows the use of alcohol among American adults is at its lowest point in a nearly 90-year downward trend.
