It used to be considered healthy — or at least the norm — to have a drink or two each evening. But more and more research has been suggesting otherwise. A new study adds evidence to the idea that drinking at even the recommended levels isn’t so healthy, and may even be harmful.
Researchers from Washington University School of Medicine in St. Louis analyzed data from over 400,000 people, ages 18 to 85. They compared the long-term mortality risk, from a number of different causes, among people who drank different levels of alcohol.
Mortality risk was lowest when people drank one to two drinks three times per week. But drinking this same amount of alcohol four to seven times per week — which is about what the current guidelines recommend — was linked to a 20 percent increase in mortality risk.
Even the lightest daily drinkers have an increased mortality risk.
The authors conclude, as other experts have, that there’s really no absolutely safe level of drinking.
“It used to seem like having one or two drinks per day was no big deal, and there even have been some studies suggesting it can improve health,” study author, Sarah M. Hartz, said in a statement. “But now we know that even the lightest daily drinkers have an increased mortality risk.”
And as we age, it makes even more sense to drink less, since mortality risk is already increasing on its own. “A 20 percent increase in risk of death is a much bigger deal in older people who already are at higher risk,” Hartz said. “Relatively few people die in their 20s, so a 20 percent increase in mortality is small but still significant. As people age, their risk of death from any cause also increases, so a 20 percent risk increase at age 75 translates into many more deaths than it does at age 25.”
The bottom line is that it may be OK to drink sparingly, particularly if you’re otherwise healthy and live a healthy lifestyle — that is, exercise, eat a plant-based diet, don’t smoke and keep a healthy weight. But the idea that we should drink for our health may be outdated, and even misleading, at this point. It will be interesting to see whether U.S. recommendations are eventually changed to reflect what a growing body of work has illustrated regarding alcohol consumption.
