Drink up!

It is good for you, even if they don't want to admit it. [Link]

So the more you drink—up to two drinks a day for woman, and four for men—the less likely you are to die. You may have heard that before, and you may have heard it doubted. But the consensus of the science is overwhelming: It is true.

Although I dispute many of the caveats offered against the life-saving benefits of alcohol, I will endorse two. First, these outcome data do not apply to women with the “breast-cancer gene” mutations (BRCA 1 or 2) or a first-degree (mother, sister) relation who has had breast cancer, for whom alcohol consumption is far riskier. Second, drinking 10 drinks Friday and Saturday nights does not convey the benefits of two or three drinks daily, even though your weekly totals would be the same: Frequent, heavy binge drinking is unhealthy. But then you knew that already, didn’t you? If you don’t distinguish binge drinking from daily moderate drinking, that would be due to Americans’ addiction-phobia, which causes them to interpret any daily drinking as addictive.

The global summary of alcohol’s benefits raises a key question: How much do you have to drink regularly before you become as likely to die as an abstainer? We’ll see below.

First, let’s address some typical objections to these findings. Of course, abstainers may not drink because they are already ill. Thus the meta-analysis relied on studies that eliminated subjects who are abstaining due to illness, or else contrast drinkers with lifetime abstainers. Additionally, objectors note, drinkers showing such longevity may be wine-sniffling, upper-middle-class professionals (virtually no study has ever found that the type of alcohol consumed impacts these results), people who exercise, eat right, and don’t smoke. To counter this argument, researchers from the prestigious Harvard Health Professionals Study published a paper which found that even men with four healthy life factors (diet, weight, non-smoking, exercise) had one-third to one-half the risk of suffering a heart attack if they had one to two drinks daily, relative to comparable men in each category who abstained.

Now let’s turn quickly to four special topics—biological mechanisms; cognitive benefits of drinking; the resveratrol myth; and the answer to our key question: If you drink just a little too much alcohol, doesn’t your death rate shoot up way over that of abstainers? (This is the so-called “J–shaped curve.”)
