Gallup poll finds more Americans are cutting their alcohol intake to zero. Health concerns are a major reason.

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 record low number of Americans are drinking, according to a new Gallup poll released this week. Just 54% of Americans said they consume alcohol at all.
