Red wine linked to anti-cancer potential...
03/09/2007- A nutrient found in red wine has shown a positive result in cancer reduction, a study in mice has found.
Researchers from the University of Alabama at Birmingham, and writing in the August edition of the Journal of Carcinogenesis, examined the effect of the plant compound resveratrol when fed to male mice with the aim of preventing prostate tumours. The study adds more weight to the health benefits of the compound. Previous studies have linked it to having a positive effect on extending survival rates of mice and preventing the negative effects of high-calorie diets. It has also been linked to diabetes, heart health and obesity. Resveratrol - an antioxidant - is also found in grapes, raspberries, peanuts and blueberries, which in turn fall under the umbrella group of superfoods. In red wine, the amount of resveratrol in a bottle can vary between types of grapes and growing seasons, and can vary between 0.2 and 5.8 milligrams per litre. But nearly all dark red wines - merlot, cabernet, zinfandel, shiraz and pinot noir - contain resveratrol. However, the amounts used in the UAB mice studies were the equivalent of one person consuming one bottle of red wine per day. General medical guidance has advised no more than one glass of wine a day for women and two for men. In the study, resveratrol-fed mice showed an 87 per cent reduction in their risk of developing prostate tumours. The mice that experienced the highest cancer-protection effect earned it after seven months of consuming resveratrol in a powdered formula mixed with their food. Other mice in the study, that developed a less-serious form of prostate cancer and were fed resveratrol, were 48 per cent more likely to have their tumor growth halted or slowed when compared to mice who did not consume the compound, the UAB research team said. This study adds to a growing body of evidence that resveratrol consumption through red wine has powerful chemoprevention properties, in addition to its apparent heart-health benefits, said lead study author Coral Lamartiniere of UAB's Department of Pharmacology and Toxicology. An earlier UAB study published May 2006 in the same journal found resveratrol-fed female mice had considerable reduction in their risk of breast cancer. He said: "A cancer prevention researcher lives for these days when they can make that kind of finding. "I drink a glass a day every evening because I'm concerned about prostate cancer. It runs in my family. "The team of researchers are now starting work to test resveratrol consumption in humans, specifically looking at the levels of concentrations needed to produce a similar effect as that which was found in the mice. The study was partly funded by the United States Department of Defense and the National Cancer Institute, but the full results have not yet been seen by NutraIngredients.com.
Experience all the benefits of red wine, without the alcohol, sulfites or calories! Promotes healthy blood pressure, cholesterol and cardiovascular health—and provides potent antioxidant protection.
Red wine is well known for its cardioprotective and other health-promoting benefits. Researchers believe resveratrol, which is highly concentrated in the skin of grapes and abundant in red wine, is the compound responsible for these benefits.
Resveratrol is produced by plants in response to injury or fungal infection. It also protects plants from UV radiation and other harmful substances. Resveratrol is believed to provide similar protective benefits for humans. Its antioxidant activity, or ability to neutralize free radicals (unstable molecules that attack healthy cells and damage membranes and DNA), may account for its cardioprotective effects. Resveratrol appears to promote healthy blood composition and circulation, and may also have anti-inflammatory properties.
A recent landmark study from Harvard Medical School, published in the medical journal Nature, found that ultra-high doses of red wine extract with resveratrol allowed obese mice to eat a high fat diet and still live a long and healthy life¹. Researchers discovered that the liver and other systems in obese mice remained healthy and fat-related deaths dropped 31 percent for those taking a resveratrol supplement.

Unlike other resveratrol supplements, which may contain molecules that have broken down over time, NSI® Longevatrol™ Stabilized Polyphenol Complex is sealed in airtight, liquid-filled capsules (Licaps®) to ensure stability and preservation of resveratrol. Each one-capsule serving delivers 100 mg of Polygonum cuspidatum standardized to 50% resveratrol, plus 100 mg of red wine extract, standardized to 40% polyphenols.
Because there is at least 50 mg of resveratrol present in each capsule, one serving is the equivalent of drinking 50 to 125 five-ounce glasses of red wine.
