If you follow the news, then you have likely heard of resveratrol, an antioxidant commonly found in red wine, grape skins and other plants.
Many people heard about resveratrol for the first time on Sunday, January 25, 2009, when the CBS News program 60 Minutes aired a segment on the promising new research surrounding resveratrol. You can watch this segment to the right.
CBS News Correspondent Morley Safer interviews Harvard University researchers Christoff Westphal and David Sinclair, who have been pursuing the genetic link between resveratrol and enzymes called sirtuins for the past 5 years.
Sirtuins are a recently discovered class of enzymes that appear to control the aging process.
In this video, Safer, Westphal and Sinclair discuss the incredible results from ongoing research aimed at identifying and isolating the exact component of resveratrol responsible for these lab results, in an effort to manufacture a pharmaceutical from this naturally-occurring compound.
Previously "Live to 150...Can You Do It?" an ABC News and Barbara Walters Special (April 1, 2008), Barbara Walters talked to researchers about the stunning research on longevity and Resveratrol. A little over a year earlier, researchers examining resveratrol made front-page news with their studies showing that resveratrol increased the life expectancy of lab animals by over 40%! Based on the results of this early research, we are expecting much more research to be done in the near future; we'll keep you posted.
Resveratrol is believed to be the plants' natural defense against adverse growing conditions and fungal attacks. While resveratrol is commonly found in red wine, it is only available in small amounts and those amounts vary greatly from wine to wine and bottle to bottle.1
Regular readers of our free monthly newsletter know all about this ongoing research. Below is a brief summary of the biggest headline-grabbing research results:
Resveratrol & Longevity
Resveratrol has been in the news over the last few years due to the results of several animal studies that found a link between resveratrol intake and significantly extended life spans. So far those studies have not been conducted on long-lived animals like humans. But the results of the animal studies are impressive to say the least. In 2003 researchers found that resveratrol increased the life span of a yeast by 70%.2 A follow-up 2006 study found a 56% increase in life span among a particular worm, Caenorhabditis elegans, and the common fruit fly, Drosophila melanogaster.3 In 2006, a study of a short-lived fish also found an extension of the animals' lives and revealed that the resveratrol delayed the onset of age-related markers.4,5 But the real break-through news on resveratrol came in the form of two studies published in the fall of 2006.6 The first of the two studies was published in the highly regarded scientific journal Nature, and found that resveratrol not only extended life by 40% in lab mice, but those same mice were eating a high calorie, high-fat diet without developing the ill-effects, such as diabetes and heart disease, that are normally associated with that kind of diet. The mice still got fat, but they stayed healthy.
Resveratrol & Athletic Endurance
In December of 2006 the scientific journal Cell published a study from researchers from the Institute of Genetics and Molecular and Cellular Biology in Illkirch, France, which reported that resveratrol doubled the athletic endurance of lab mice, controlled weight gain, and prevented diabetes.7
