It is an irresistible headline: People who drink alcohol in moderation actually live longer than those who abstain entirely. Counterintuitive studies that show the purported benefits of a drink or two a day prompt flurries of bright news reports. You can hear the glasses clinking.
Buzz kill: It is probably not true, according to a new analysis of existing research published in the peer-reviewed Journal of Studies on Alcohol and Drugs.
It turns out that many studies showing that moderate drinkers live longer than nondrinkers suffer from a big flaw: The "abstainers" category includes people who used to drink but have stopped, sometimes for health reasons. They may be inherently less healthy, as a group, than people who drink in moderation. That doesn't mean that drinking in moderation causes people to live longer.
