(Reuters) -U.S. Dietary Guidelines are expected to eliminate the long-standing recommendation that adults limit alcohol consumption to one or two drinks per day, according to three sources familiar with the matter, in what could be a major win for an industry threatened by heightened scrutiny of alcohol's health effects. The updated Dietary Guidelines for Americans, which could be released as early as this month, are expected to include a brief statement encouraging Americans to drink in moderation or limit alcohol intake due to associated health risks, the sources said. The guidelines are still under development and subject to change, two of the sources and a fourth individual familiar with the process said.
