Moderate drinking and statistical health outcomes

Aaron Carroll debunks some myths about booze and health:

Over the past year, I’ve tried to clear up a lot of the misconceptions on food and drink: about salt, artificial sweeteners, among others, even water.

Now let me take on alcohol: wine, beer and cocktails. Although I have written about the dangerous effects of alcohol abuse and misuse, that doesn’t mean it’s always bad. A part of many complex and delicious adult beverages, alcohol is linked to a number of health benefits in medical studies.

That doesn’t mean the studies provide only good news, either, or that the evidence in its favor is a slam dunk. You won’t be surprised to hear that, once again, my watchword — moderation — applies.

Research into how alcohol consumption affects health has been going on for a long time. A 1990 prospective cohort study included results of more than 275,000 men followed since 1959. Compared with those who never drank alcohol, those who consumed one to two drinks a day had a significantly reduced mortality rate from both coronary heart disease and “all causes.” Those who consumed three or more drinks a day still had a lower risk of death from coronary heart disease, but had a higher mortality rate over all.

A 2004 study came to similar conclusions. It followed about 6,600 men and 8,000 women for five years and found that compared with those who drank about one drink a day on average, those who didn’t drink at all and those who drank more than two drinks a day had higher rates of death. Results like these have been consistent across a number of studies in different populations. Even studies published in the journal Alcoholism: Clinical and Experimental Research agree that moderate drinking seems to be associated with a decreased risk of death over all.

However, alcohol seems to have different effects on different diseases. Almost all of the major benefits of drinking are seen in cardiovascular illnesses. In fact, with men, even consumption of a surprisingly large amount can seem protective.
