Several recent studies have suggested that alcohol in moderation offers health benefits and may even help you live longer.
Yet in 2014, the World Health Organization labeled alcohol as a carcinogen and said no amount is safe.
The question gained new relevance this month with the release of a sobering report that documents a significant rise in the number of people with drinking problems in the U.S. The problems were noted especially among women, minorities, and the elderly, as well as those with less education and lower incomes.
Is any amount of alcohol better than none at all?
A large study published this month illustrates his point. It showed that light to moderate drinkers lowered their chances of an early death by about 20%, compared with nondrinkers. Their risk of dying from heart disease dropped even more dramatically. But only light drinkers saw a drop in cancer deaths. Light drinkers were those who had fewer than three drinks per week, while moderate drinkers had more than three drinks, but no more than 14 for men and seven for women per week.
Heavy drinkers, on the other hand, fared considerably worse. They had a 27% higher chance of dying of cancer and an 11% higher chance of dying early from any cause. Binge drinkers had similar risks.
“It’s clear that heavy drinking is bad for your health, and it’s bad for nearly every aspect of your health,” says Mukamal, “but even occasionally exceeding these limits is often bad for one’s health, even if you normally drink moderately.”
Recent studies have also looked at how moderate drinking affects the aging brain. One published this month found that daily drinkers (up to three drinks for women and four drinks for men) were about twice as likely as nondrinkers to live to 85 without thinking and memory problems.
Alison Moore, MD, studies alcohol’s impact on older people. A geriatrician at the University of California San Diego, she says its possible positive effects on heart health may, in turn, protect against
So, how do you decide whether or not to take a drink, let alone how much and how often? It’s complicated.
“This is a very, very individual issue,” says cardiologist Suzanne Steinbaum, DO, the director of Women’s Heart Health at Lenox Hill Hospital in New York City. “There’s no one size fits all for alcohol.”
Federal dietary guidelines recommend no more than one drink per day for women and two drinks per day for men. Women are advised to drink less than men because their bodies absorb more alcohol and metabolize it more slowly. Man or woman, it’s critical to pay attention to portion sizes when pouring a drink or when ordering at a restaurant, says Steinbaum. Your one glass of wine could easily contain the equivalent of two or more drinks.
Alcohol can make you more prone to falls and can boost your blood pressure. It also contains a lot of sugar, a concern for anyone with diabetes or prediabetes, she says.
Finally, alcohol’s possible health benefits only become relevant later in life, when you’re more likely to have chronic diseases, says Mukamal.
“When you’re young and at low risk of disease, there’s practically no chance that drinking is good for you. At best, it may be neutral,” he says. “But you are at risk for all of the harms related to alcohol. Young people should focus on developing responsible drinking habits rather than the health benefits.”
Talk to your doctor about any concerns, but know that they have imperfect evidence and can’t offer a definite answer, Mukamal says. While large studies designed to better answer questions about the health benefits and risks are being planned, the results may be a decade away.
