A report that is intended to shape the next edition of the U.S. Dietary Guidelines has broken sharply with an emerging scientific consensus that alcohol has no health benefits.
The evidence review, by the National Academies of Sciences, Engineering, and Medicine in December, revived a once-dominant hypothesis that moderate drinking is linked to fewer heart attack and stroke deaths, and fewer deaths overall, compared with never drinking.
Many scientists now take issue with that view. And some fear that, based on the new analysis, the influential dietary guidelines may fail to address recent research into the harms of drinking.
The guidelines are revised once every five years, and there have been growing concerns about rising alcohol consumption in the United States in recent decades.
“This report is a thinly veiled effort to undo the growing evidence that alcohol causes cancer and is increasingly associated with serious health outcomes,” said Diane Riibe, who co-founded the U.S. Alcohol Policy Alliance, a nonprofit focused on the harms of alcohol.
The report did note a small but significantly heightened risk of breast cancer associated with moderate drinking, but said there wasn’t enough evidence to link moderate consumption to other cancers. The National Cancer Institute, among other scientific bodies, disagrees.
