Red Wine and Breast Cancer

(Ivanhoe Newswire) Whether it’s burgundy, merlot or Chianti, if it’s made from a red grape it could prevent the development of breast cancer.

New research from the University of Nebraska Medical Center shows that resveratrol, a natural substance found in red wine and red grapes, can suppress the formation of estrogen DNA adducts.

Although breast cancer formation involves a multitude of steps, most are fueled by increased estrogen. It collects and reacts with DNA molecules. Resveratrol, which is also sold in extract as a dietary supplement, prevents the formation of the adducts. It also suppressed two other known risk factors for breast cancer.

“We believe this could stop the whole progression that leads to breast cancer down the road,” said the study’s lead author Eleanor G. Rogan, Ph.D.

The amount of resveratrol found in one glass of red wine is enough to suppress the DNA adducts. The study was conduced in laboratory cultures and will need to be confirmed in larger human trials.
