PISCATAWAY, NJ – Probably everyone has heard the conventional wisdom that a glass of wine a day is good for you--or you’ve heard some variation of it. The problem is that it’s based on flawed scientific research, according to a new report in the Journal of Studies on Alcohol and Drugs. Over the years, many studies have suggested that moderate drinkers enjoy longer lives with lower risks of heart disease and other chronic ills than abstainers do. That spurred the widespread belief that alcohol, in moderation, can be a health tonic. However, not all studies have painted such a rosy picture--and the ...
