Many people believe that having a glass of wine with dinner — or moderately drinking any kind of alcohol — will protect them from heart disease. But a hard look at the evidence finds little support for that.
That’s the conclusion of a new research review in the May 2017 issue of the Journal of Studies on Alcohol and Drugs.
Over the years, studies have found that adults who drink moderately have lower heart disease rates than non-drinkers. That has spurred the widespread belief that alcohol, in moderation, does a heart good.
But the new analysis, of 45 previous cohort studies, reveals the flaws in that assumption: A central issue is that “non-drinkers” may, in fact, be former drinkers who quit or cut down for health reasons.
