    Live Longer, Drink red wine

    New Hints Seen That Red Wine May Slow Aging
    By NICHOLAS WADE



    Published: June 4, 2008
    Red wine may be much more potent than was thought in extending human lifespan, researchers say in a new report that is likely to give impetus to the rapidly growing search for longevity drugs.
    The study is based on dosing mice with resveratrol, an ingredient of some red wines. Some scientists are already taking resveratrol in capsule form, but others believe it is far too early to take the drug, especially using wine as its source, until there is better data on its safety and effectiveness.




    The report is part of a new wave of interest in drugs that may enhance longevity. On Monday, Sirtris, a startup founded in 2004 to develop drugs with the same effects as resveratrol, completed its sale to GlaxoSmithKline for $720 million.
    Sirtris is seeking to develop drugs that activate protein agents known in people as sirtuins.
    “The upside is so huge that if we are right, the company that dominates the sirtuin space could dominate the pharmaceutical industry and change medicine,” Dr. David Sinclair of the Harvard Medical School, a co-founder of the company, said Tuesday.
    Serious scientists have long derided the idea of life-extending elixirs, but the door has now been opened to drugs that exploit an ancient biological survival mechanism, that of switching the body’s resources from fertility to tissue maintenance. The improved tissue maintenance seems to extend life by cutting down on the degenerative diseases of aging.
    The reflex can be prompted by a faminelike diet, known as caloric restriction, which extends the life of laboratory rodents by up to 30 percent but is far too hard for most people to keep to and in any case has not been proven to work in humans.
    Research started nearly 20 years ago by Dr. Leonard Guarente of the Massachusetts Institute of Technology showed recently that the famine-induced switch to tissue preservation might be triggered by activating the body’s sirtuins. Dr. Sinclair, a former student of Dr. Guarente, then found in 2003 that sirtuins could be activated by some natural compounds, including resveratrol, previously known as just an ingredient of certain red wines.
    Dr. Sinclair’s finding led in several directions. He and others have tested resveratrol’s effects in mice, mostly at doses far higher than the minuscule amounts in red wine. One of the more spectacular results was obtained last year by Dr. John Auwerx of the Institute of Genetics and Molecular and Cellular Biology in Illkirch, France. He showed that resveratrol could turn plain vanilla, couch-potato mice into champion athletes, making them run twice as far on a treadmill before collapsing.
    The company Sirtris, meanwhile, has been testing resveratrol and other drugs that activate sirtuin. These drugs are small molecules, more stable than resveratrol, and can be given in smaller doses. In April, Sirtris reported that its formulation of resveratrol, called SRT501, reduced glucose levels in diabetic patients.
    The company plans to start clinical trials of its resveratrol mimic soon. Sirtris’s value to GlaxoSmithKline is presumably that its sirtuin-activating drugs could be used to treat a spectrum of degenerative diseases, like cancer and Alzheimer’s, if the underlying theory is correct.
    Separately from Sirtris’s investigations, a research team led by Tomas A. Prolla and Richard Weindruch, of the University of Wisconsin, reports in the journal PLoS One on Wednesday that resveratrol may be effective in mice and people in much lower doses than previously thought necessary. In earlier studies, like Dr. Auwerx’s of mice on treadmills, the animals were fed such large amounts of resveratrol that to gain equivalent dosages people would have to drink more than 100 bottles of red wine a day.
    The Wisconsin scientists used a dose on mice equivalent to just 35 bottles a day. But red wine contains many other resveratrol-like compounds that may also be beneficial. Taking these into account, as well as mice’s higher metabolic rate, a mere four, five-ounce glasses of wine “starts getting close” to the amount of resveratrol they found effective, Dr. Weindruch said.
    Resveratrol can also be obtained in the form of capsules marketed by several companies. Those made by one company, Longevinex, include extracts of red wine and of a Chinese plant called giant knotweed. The Wisconsin researchers conclude that resveratrol can mimic many of the effects of a caloric-restricted diet “at doses that can readily be achieved in humans.”
    The effectiveness of the low doses was not tested directly, however, but with a DNA chip that measures changes in the activity of genes. The Wisconsin team first defined the pattern of gene activity established in mice on caloric restriction, and then showed that very low doses of resveratrol produced just the same pattern.

    Re: Live Longer, Drink red wine

    I heard that study (or a similar one) a couple of years ago, and have started to drink red wine more regularly. I guess merlot would be my fave.

    Whenever I watch "Sideways" I get inspired to drink wine and do for a while, then fall off.

    On a side note, why do I love that movie some much?

    Re: Live Longer, Drink red wine

    I've been wanting to make Resveratrol a daily part of my supplementation routine, but there are reports that high doses (500mg +) can trigger bouts of tendonitis.

    I've had enough shoulder problems in my life that I'd prefer to avoid them in the future.

    when will they do a study on Bacardi?

    I think people have been studying the short term and long term effects of Bacardi-like substaces for centuries...
