Does resveratrol improve memory?


Red wine and a substance in it called resveratrol have been getting a lot of press lately as being good for your heart. Resveratrol, an antioxidant, has received the most attention from researchers, since it seems to help prevent damage to blood vessels, reduces "bad" cholesterol and prevents blood clots. Now scientists at the University of Florida's Institute on Aging are preparing to test whether resveratrol can help improve memory and physical function in older adults. What they need for the 12-week clinical trial are volunteers who are willing to try a dietary supplement. One group will get a supplement with resveratrol while a second group gets a supplement without the antioxidant compound. Neither group will be offered glasses of red wine to test their memory. Resveratrol is found in red wine and the dark-skinned grapes that go into it, and in animal studies it has been shown to improve memory and reasoning skills. It is one of a small number of compounds shown to extend the lifespan of flies, fish and other organisms.

A Valentine's toast to your heart


Valentine's Day usually turns to thoughts of love, romance and celebrating the moment with a pleasing meal and possibly a glass of bubbly. Restaurants plan special menus that offer three to five courses with optional wine pairings. And chocolate desserts are a given.

My romantic thoughts this Valentine's Day turn to celebrating (hopefully) the good health of that special someone in your life. And lifting a glass of red wine may play a role in this process.Health benefits

The question whether wine is good for you is a hot topic of discussion these days. It is challenging for the medical community to come out in favor of alcohol consumption, although they are intrigued by the benefits of a glass of red wine.

Numerous studies show that wine can have some positive health benefits by reducing the risk of heart disease and certain cancers. Like most things, moderation is the key. It is recommended that men have no more than two drinks per day and women should limit their consumption to one drink per day.

Resveratrol Protects Lungs


Red-wine chemical aids the orderly destruction of precancerous cells during smoking.The inhalation of smoke, especially from cigarettes, is a leading cause of lung cancer. But new research on lung cells in a lab shows a glass or two of red wine may help prevent the disease.

In 2009, the American Cancer Society recorded 219,440 new cases of lung cancer and 159,390 deaths from the disease, making it the leading cause of cancer death in both men and women. A team of researchers from the University of California at Merced has focused their attention on resveratrol, to see if its properties as an antioxidant may prevent lung cancer development. Before tumors grow in lung tissue, there is inflammation partly due to the buildup of toxic free radicals. As an antioxidant, resveratrol acts as an anti-inflammatory, binding with and removing free radicals.

But what the researchers found caught them completely off guard. "Resveratrol did not chemically remove free radicals," during the experiment, said researcher Dr. Henry Forman, a professor at the Merced school of natural sciences.

Among people who use multiple dietary supplements, fish oil/omega-3 supplements now top multivitamins in popularity, according to a recent survey by ConsumerLab.com. The survey also shows that vitamin D use jumped 30% since last year and resveratrol use surged by 66%. The ConsumerLab.com survey is based on 6,012 responses collected in November from a sampling of subscribers to the ConsumerLab.com free e-newsletter. Most respondents use multiple supplements.

“We conduct the annual survey to help direct our product testing toward categories and brands of greatest interest to our subscribers; but the survey also yields insight into the nutrition marketplace,” said Tod Cooperman, MD, President of ConsumerLab.com. Among the survey’s key findings:

· Fish oil/omega-3 supplements were used by 74.0% of respondents (up from 71.6% in 2008), followed in popularity by multivitamins, which were used by 72% (down from 73.8% in the prior year). Among the heaviest supplement users (10 or more per day), 87% used fish oil. The percentage of people using fish oil/omega-3 remained steady among those aged 35 through 74, dropping slightly among older people.

Pfizer scientists in Groton, led by Kay Ahn, are refuting a claim that indicates resveratrol, a key component in red wine, can slow the aging process, the Day of New London reports.
The scientists published the research last month in the Journal of Biological Chemistry, calling into question previous research suggesting resveratrol boosts an enzyme that slows the aging process."Efforts to slow the march of old age with a pill have been dealt a blow," New Scientist magazine reports.
Philip Norrie, an Australian doctor who has written books about wine and health, said people shouldn't give up on resveratrol or the health benefits of drinking moderate amounts of red wine.
