A couple of drinks a day aren’t bad for you and may even be good for you.

Right?

That’s been the message — from researchers, governments, and beverage companies — for decades. And as a result, many of us don’t think twice about tossing back a couple of glasses or wine or a few beers after work.

But maybe we should. Because it turns out the story about the health effects of moderate drinking is shifting pretty dramatically. New research on alcohol and mortality, and a growing awareness about the rise in alcohol-related deaths in the US, is causing a reckoning among researchers about even moderate levels of alcohol consumption.

In particular, an impressive new meta-study involving 600,000 participants, published recently in The Lancet, suggests that levels of alcohol previously thought to be relatively harmless are linked with an earlier death. What’s more, drinking small amounts of alcohol may not carry all the long-touted protective effects on the cardiovascular system.

“For years, there was a sense that there was an optimal level which was not drinking no alcohol but drinking moderately that led to the best health outcomes,” said Duke University’s Dan Blazer, an author of the paper. “I think we’re going to have to rethink that a bit.”

Alongside this study have come disturbing reports of the alcohol industry’s involvement in funding science that may have helped drinking look more favorable, as well as a growing worry that many people are naive about alcohol’s health effects. How many people know, for example, that as far back as 1988, the World Health Organization’s International Agency for Research on Cancer designated alcohol a level-one carcinogen? Some say too few.

Maybe it’s time that changes — with some caveats, as usual.
