Until recently, very few people had ever heard of raspberry ketones, the aromatic compounds that give the berries their distinctive smell. Today, health food stores have trouble keeping the capsules or drops of the stuff on their shelves. Almost overnight, an obscure plant compound became the next big thing in weight loss - and all it took was a few words from Dr. Oz. In a February episode of "The Dr. Oz Show," Mehmet Oz told viewers that raspberry ketones were "the No. 1 miracle in a bottle to burn your fat. " Once Oz calls something a "miracle," it doesn't remain obscure for long.

THE NAME needs jazzing up -- try making a jingle out of "resveratrol" -- but we foresee huge advertising campaigns built around the miracle substance derived from the skins of grapes. This could be the chemical for 21st century America, the mechanism by which couch potatoes can have their transfats and eat them too. Maybe that's a tad optimistic.

Like aspirin and the heart medicine digitalis, resveratrol is a plant extract -- one with seemingly powerful and broad effects on living organisms. It acts as a phytoestrogen, mimicking many of the hormone estrogen's effects. In the cells of rodents as well as humans, it disrupts the genetic machinery that gives rise to inflammation and to cancerous tumors. In cell cultures of brain tissue, it even cleans up the tangled amyloid deposits that are the hallmark of Alzheimer's disease.

The pitches for resveratrol are as ubiquitous as they are dazzling. Fire up a search engine for red wine, resveratrol or longevity, and the entreaties of supplement makers will line your screen, blinking promises of weight loss, wrinkle reduction, greater vitality and -- yes -- even "increased erection hardness . . . sexual sensitivity, pleasure and ejaculatory volume." But that's not all.

Take too much fun from the fun bank at Thanksgiving? With more holiday revelry coming up, we have three little words: alcohol-free wine. The notion of tinkering with perfectly good vino makes true wine lovers blanch, but alcohol-free wine has some advantages over its boozy cousin, including far fewer calories: about 15 to 25 calories for a 4-ounce glass, compared with about 90 for a glass of Chardonnay or Cabernet Sauvignon.

Researchers believe they have unlocked the mystery of how an antioxidant found in grapes and red wine fights cancer. A study published Friday concludes that the compound resveratrol, which acts like an antibiotic to protect grapes from fungus, may turn off a protein that guards cancer cells from cancer-fighting therapies such as chemotherapy.

Drinking red wine could protect against lung cancer, but white wine may increase the risk slightly, Spanish scientists reported Thursday in the journal Thorax. Red wine contains tannins and resveratrol, both of which are known to have anti-tumor properties. Tannins mop up dangerous free radicals. The negative effects of white wine may result from the alcohol. From Times Staff and Wire Reports

Red wine may or may not extend your life, but it is invigorating the wine industry. Market research firm ACNielsen this week reported a bump in red wine sales after a series of medical studies about the anti-aging properties of a compound called resveratrol, which is found in red wine. True, the experiments were in mice. And, yes, a human would have to drink hundreds of glasses a day to get an equivalent dose of resveratrol. But who's counting?

"To a long life" may be more than just a wine drinker's toast. First, researchers found that red wine helps keep the heart ticking. Now, studies show that a substance in grapes may prevent cancer. Researchers working with cell cultures and laboratory animals have found that a substance in grapes called resveratrol can help keep cells from turning cancerous and inhibit the spread of cells that already are malignant.

An ingredient in red wine extends lifespan and alleviates disease when fed in huge quantities to obese mice, even though the mice remain fat, researchers reported today in the online edition of the journal Nature. To reach an equivalent dosage, a human would have to drink about 20 bottles of red wine per day. The chemical, called resveratrol, has previously been found to have life-prolonging effects on yeast, roundworms, flies and fish.
