wine and health

What would the ideal anti-aging skin care product look like? To begin with, it would need to provide protection against sun damage from UV exposure . [i] Of course any sunscreen does that, so what we really want is something that can help reverse the effects of UV exposure, which include mutations in the DNA of skin cells. This is where the idea of working at a molecular level comes into play. While many products talk about “DNA repair” the evidence for a role for resveratrol is particularly strong. There are several ways that resveratrol functions in this regard, the best known of which is its powerful antioxidant effects. Healthier DNA means not only more attractive skin but a lower risk of skin cancers . The use of antioxidants such as resveratrol to lower risk of skin cancer is known as chemoprevention. There is evidence that it may help prevent many other types of cancer as well. Another measure of aging has to do with integrity of sequences on the ends of the chromosom...

  Part 1 Recently I was honored to join Professors David Sinclair of Harvard and Joseph Vercauteren of the University of Montpelleir at an anti-aging symposium at the invitation of Mathilde Thomas of Caudalie in Paris. Caudalie has been using wine extracts (and specifically resveratrol) in their products for more than 15 years, after Vercauteren identified it in wine grape vines. Sinclair has become well known for his work identifying the role of sirtuin (SIRT) genes in anti-aging, and resveratrol as a natural sirtuin activator. While much remains to be proven, it is fair to say that science is finally beginning to have an impact on skin care. With an increasing understanding of what causes aging in skin cells and how botanical antioxidants such as resveratrol work at a molecular level, there is no excuse to use anti-aging skin care products that don’t multitask. Before delving into the potential benefits of resveratrol in skin care, it may help to review ho...

Just when we thought the bloom was off the rosé for resveratrol, the anti-oxidant polyphenol from red wine with multiple anti-aging properties, along comes new research giving life to the debate. But first a bit of background: As I detailed in my book Age Gets Better with Wine , it is well-documented that wine drinkers live longer and have lower rates of many diseases of aging. Much or the credit for this has been given to resveratrol, though there isn’t nearly enough of it in wine to explain the effects. Nevertheless, I dubbed it the “miracle molecule” and when it was reported to activate a unique life-extension phenomenon via a genetic trigger called SIRT, an industry was born, led by Sirtris Pharmaceuticals, quickly acquired by pharma giant Glaxo. The hope was that resveratrol science could lead to compounds enabling people to live up to 150 years and with a good quality of life. But alas, researchers from other labs could not duplicate the results, and clinical studies disa...

We are closing in on the list of 101 healthy reasons to drink wine, and my book "Age Gets Better with Wine" will be on bookshelves soon. (You can pre-order it at any of the major retailers now.) So we turn now to one of the most exciting aspects of wine, one which has opened a new frontier in anti-aging research. Resveratrol from red wine was identified a few years ago as the only significant natural activator of a family of enzymes called sirtuins, coded by the SIRT gene (hence the name). A long list of specific benefits are being discovered for sirtuins, beyond what resveratrol and other polyphenols do independently, and we will list only a few of them here. 96. It has been known for many years that caloric restriction - reducing an organism's caloric intake by around 40% of what it would normally consume - will extend its life by a similar percentage. Sirtuins were found to be the key to this effect, and when researchers discovered that by feeding the subject resveratr...
