U.S. โ Itโs wine time. Beer Thirty. Happy hour. Five oโclock somewhere.
Maybe it’s also time to rethinkย drinking?
Moderate drinkingย was once thought to have benefits for the heart, but better research methods have thrown cold water on that.
โDrinking less is a great way to be healthier,โ said Dr. Timothy Naimi, who directs the Canadian Institute for Substance Use Research at the University of Victoria in British Columbia.
ARE DRINKING GUIDELINES CHANGING?
Guidelines vary a lot from country to country but the overall trend is toward drinking less.
The United Kingdom, France, Denmark, Holland and Australia recently reviewed new evidence and lowered their alcohol consumption recommendations. Ireland will require cancer warning labels on alcohol starting in 2026.
โThe scientific consensus has shifted due to the overwhelming evidence linking alcohol to over 200 health conditions, including cancers, cardiovascular diseases and injuries,โ said Carina Ferreira-Borges, regional adviser for alcohol at the World Health Organization regional office for Europe.
From Dry January to Sober October to bartendersย getting creative with non-alcoholic cocktails, there’s a cultural vibe that supports cutting back.
“People my age are way more accepting of it,” said Tessa Weber, 28, of Austin, Texas. She stopped drinking for Dry January this year because she’d noticed alcohol was increasing her anxiety. She liked the results โ better sleep, more energy โ and has stuck with it.
โItโs good to reevaluate your relationship with alcohol,โ Weber said.
WAIT, MODERATE DRINKING DOESN’T HAVE HEALTH BENEFITS?
That idea came from imperfect studies comparing groups of people by how much they drink. Usually, consumption was measured at one point in time. And none of the studies randomly assigned people to drink or not drink, so they couldnโt prove cause and effect.
People who report drinking moderately tend to have higher levels of education, higher incomes and better access to health care, Naimi said.
โIt turns out that when you adjust for those things, the benefits tend to disappear,โ he said.
Another problem: Most studies didnโt include younger people. Almost half of the people who die from alcohol-related causes die before the age of 50.
โIf youโre studying people who survived into middle age, didnโt quit drinking because of a problem and didnโt become a heavy drinker, thatโs a very select group,โ Naimi said. โIt creates an appearance of a benefit for moderate drinkers that is actually a statistical illusion.โ
Other studies challenge the idea that alcohol has benefits. These studies compare people with a gene variant that makes it unpleasant to drink to people without the gene variant. People with the variant tend to drink very little or not at all.ย One of these studiesย found people with the gene variant have a lower risk of heart disease โ another blow to the idea that alcohol protects people from heart problems.
HOW MANY DRINKS CAN I HAVE PER DAY?
That depends.
Drinking raises theย risk of several types of cancer, including colon, liver, breast and mouth and throat. Alcohol breaks down in the body into a substance called acetaldehyde, which can damage your cells and stop them from repairing themselves. That creates the conditions for cancer to grow.
Thousands of U.S. deaths per yearย could be preventedย if people followed the governmentโs dietary guidelines, which advise men to limit themselves to two drinks or fewer per day and women to one drink or fewer per day, Naimi said.
One drink is the equivalent of about one 12-ounce can of beer, a 5-ounce glass of wine or a shot of liquor.
Naimi served on an advisory committee that wanted to lower the recommendation for men toย one drink per day. That advice was ignored whenย the federal recommendationsย came out in 2020.
โThe simple message thatโs best supported by the evidence is that, if you drink, less is better when it comes to health,โ Naimi said.
