Occasional drink does not have any health benefits, says new study

Health benefits associated with moderate drinking may not be as strong as previous studies suggest, That’s according to new research analysis published in The Journal of Studies on Alcohol and Drugs.

“I wish it were true,” Tim Stockwell, director UVic’s Centre for Addictions Research of British Columbia and the study’s lead author, said with a laugh. “I like a drink and I wish it did me good … But there’s various grounds for skepticism, unfortunately.”

The research out of the University of Victoria’s Centre for Addictions Research of B-C looks at 87 past research experiments involving more than four-million people.

At first, the data showed that “low-volume drinkers” (those who had up to two drinks a day) had lower mortality risks than those who abstained from alcohol. They also found that “occasional drinkers” (people who consume less than one drink a week) live the longest.

But after looking at the quality of each study and adjusting for errors, the researchers found that the protective effect of light drinking vanished.
The study builds on a landmark 2006 study also co-authored by Stockwell that found most published studies on alcohol use and mortality make the mistake of comparing moderate drinkers to those who currently abstain.

“We know from other studies that, as we age, people in developed countries tend to cut down or stop completely their drinking,” he said.

Since current abstainers include many people who have cut down or cut out alcohol due to poor health, that skews the data by making the health and life expectancy of moderate drinkers look good by comparison, he said.

He said the paper’s findings suggest that improved methods are needed for scientists to study the health effects of alcohol. Following the 2006 study, Stockwell and his colleagues could only find 13 studies out of 87 that adjusted for these errors.

“The bottom line is that we need to be more skeptical of claims that low-volume alcohol consumption is good for you, and a take a long, hard look at how studies around alcohol and health are designed,” he said.
Improving the research could have a significant impact on both alcohol policies, as well as guidance that physicians give to patients about low-risk drinking, he said.
Stockwell’s advice?

“If you like a glass of wine a day, it’s probably not doing you much harm if you enjoy it,” he said. “Do it for the pleasure but do not believe or comfort yourself by thinking it’s good for your health.”
