The Buzz about Grape Juice
OK, it's not wine. But it has many of its health benefits.
April 3, 2000 (Petaluma, Calif.) -- Even the most heartening news about the health benefits of wine wasn't enough to convince Susan Sanford to imbibe. "I've just never liked the taste of alcohol," says Sanford, 42, a film sound engineer in Northern California. "Still, with all the headlines, you can't help wondering whether you're missing out on something that might lower your risk of heart disease."
Well, Susan Sanford, worry no more. If you don't like wine, the latest studies show you can get almost all the same benefits from grape juice. The reason: Purple grape juice contains the same powerful disease-fighting antioxidants, called flavonoids, that are believed to give wine many of its heart-friendly benefits.
What'll It Be: Wine or Welch's?
The flavonoids in grape juice, like those in wine, have been shown to prevent the oxidation of so-called bad cholesterol (LDLs, or low-density lipoproteins) that leads to formation of plaque in artery walls. In a study published in 1999 in the journal Circulation, researchers at the University of Wisconsin Medical School in Madison asked 15 patients who already showed clinical signs of cardiovascular disease -- including plaque-constricted arteries -- to drink a tall glass of grape juice daily. After 14 days, blood tests revealed that LDL oxidation in these patients was significantly reduced. And ultrasound images showed changes in the artery walls, indicating that their blood was flowing more freely.
