Now hear this: wine prevents hearing loss

92. Loss of hearing is no laughing matter, and it can occur from either age-related decline or acoustic trauma (loud noise.) A few years ago, a group or researchers decide to see if resveratrol could play a role. Ealry indications were that becaue oxidative damage contributes to hearing loss, antioxidants such as resveratrol could be helpful. However, a more direct way to test it is with noise-induced hearing loss. A group of rats (hard rock fans, no doubt) were recruited to test whether resveratrol could prevent hearing loss induced by standardized noise exposure. It turns out that indeed it does, as if we are surprised.

Revisiting resveratrol: new findings rekindle anti-aging debate

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...

new resveratrol revelations

What a year it has been for resveratrol, the polyphenol molecule from red wine. Last year at this time it was the toast of the town, having been credited with triggering a metabolic change leading to increased lifespan in experimental models, then catapulted into the limelight as a potential cancer cure with clinical trials under the auspices of pharma giant GlaxoSmithKline. Sales of resveratrol supplements were skyrocketing, with audacious claims about weight loss, brain power, and longevity, never mind that none of this had been proven in humans. But with the new year came new controversy. Two of Glaxo’s competitors, Pfizer and Amgen, published their own studies on resveratrol, concluding that the longevity effect was false, an artifact of the testing method. What few clinical trials there are in humans revealed that it is poorly absorbed and doesn’t last very long in the body anyway. Then in November Glaxo abruptly announced the suspension of the clinical trial and all further devel...
