Resveratrol Stops Breast Cancer Growth, Study Suggests

This might be the main reason diets rich in grape tanins can protect societies along the Mediterranean but now even these regions are consuming the rich Western Diet. This is still not a magic bulletin or a replacement for a healthy diet.

ScienceDaily (Sep. 29, 2011) — A new research report appearing in the October 2011 issue of The FASEB Journal shows that resveratrol, the “healthy” ingredient in red wine, stops breast cancer cells from growing by blocking the growth effects of estrogen. This discovery, made by a team of American and Italian scientists, suggests for the first time that resveratrol is able to counteract the malignant progression since it inhibits the proliferation of hormone resistant breast cancer cells. This has important implications for the treatment of women with breast cancer whose tumors eventually develop resistance to hormonal therapy.

Some extra info on resveratrol.

Summary (

  • Resveratrol is a polyphenolic compound found in grapes, red wine, purple grape juice, peanuts, and some berries. (More Information)
  • When taken orally, resveratrol appears to be well-absorbed by humans, but its bioavailability is relatively low because it is rapidly metabolized and eliminated. (More Information)
  • Scientists became interested in exploring potential health benefits of resveratrol when its presence was reported in red wine, leading to speculation that resveratrol might help explain the “French Paradox.” (More Information)
  • Moderate alcohol consumption has been consistently associated with 20-30% reductions in coronary heart disease risk, but it is not yet clear whether red wine polyphenols, such as resveratrol, confer any additional risk reduction. (More Information)
  • Although resveratrol can inhibit the growth of cancer cells in culture and in some animal models, it is not known whether high intakes of resveratrol can prevent cancer in humans. (More Information)
  • Resveratrol administration has increased the lifespans of yeast, worms, fruit flies, fish, and mice fed a high-calorie diet, but it is not known whether resveratrol will have similar effects in humans. (More Information)
  • At present, relatively little is known about the effects of resveratrol in humans.
