wine and health

In an era of fake news, alternative facts, and conflicting advice on healthy drinking from even the most reliable sources, it is important to understand where reporting on clinical science can go awry. Does a glass of wine before bed help you to lose weight? A widely reported study last year seemed to suggest just that, at least if you only looked at the headlines. How about a glass of wine a day is as good as an hour at the gym? Both of these might be true - if you are a mouse - and substituting resveratrol for wine. Of mice and men - and medicine The journey from the research lab to the clinic is known as translational medicine, and the process can be long and unpredictable. Take for example the hypothesis that resveratrol alters metabolism in a way that mimics exercise (and ignore for the moment the separate idea that resveratrol supplementation is the same as drinking wine.)  There are limits on what sort of interventional studies you can do to test this idea on humans, ...

Resveratrol, the miracle molecule from red wine, has rocketed from relative obscurity to celebrity status in the supplement market. Its multiple anti-aging properties are given credit for this, and I used resveratrol research in my book “Age Gets Better with Wine” to explain why moderate regular consumption of red wine is a healthy thing. Supplement marketers now proclaim that resveratrol pills have “all the benefits of wine without the alcohol” and tout their own special formulas. Yet there remains a lack of large well-controlled clinical studies to back up these claims. A relatively new field of medical science called translational medicine helps explain the problem. Often called “bench to bedside” research, translational medicine seeks to bridge the gap between laboratory studies and validated clinical treatments. The challenge of translational medicine is enormous, given that more than 90% of treatments (say for example a drug or supplement) fail in human trials after...
