wine and health

For this post I decided to address what I see as a neo-prohibitionist and paternalistic trend in medical advice about drinking, with a point-counterpoint on a blog that appeared recently on self.com. I believe the author made a sincere attempt to get the story right but was misinformed by the physicians she quotes. What was not disclosed is that the meta-analysis that this story references was done under the auspices of the Centre for Addictions Research of British Columbia, University of Victoria, an institution with a presumed anti-alcohol bias. An invited commentary with the original publication  came from the Alcohol Research Group in Emeryville, CA, whose mission “seeks to reduce alcohol-related harms.” They lauded the findings, saying that it could help fight back against “renewed calls from certain medical commentators to prescribe moderate drinking.” Disclosure: I count myself among those medical commentators. http://www.self.com/story/red-wine-heart-health-analysis He...

In order to make sense of the seemingly conflicting reports about wine and health there’s one essential thing to understand: the J-shaped curve. It’s a simple concept, universal, in plain sight, and often ignored. It goes like this: Take “nondrinking” as the baseline and plot increased or decreased relative risk of a health issue with increasing levels of daily consumption. Nondrinkers have a certain risk of, say heart attacks, moderate drinkers a lower risk, heavy drinkers a relatively higher risk. Not too complicated. The tricky parts are separating wine drinkers from drinkers in general, and daily moderate drinkers from occasional drinkers. The J-curve is not just about wine The J-shaped curve is too universal to ignore once you see it. Even dietary salt intake has a J-curve; consuming too little in your diet can be as harmful as too much. For years, the American Heart Association has endorsed a 1.5 gram per day limit on sodium intake (salt is about 40% sodium), about what ...
