There's also heartening news for women who enjoy the heart-protecting power of alcohol but worry about its possible role in breast cancer. In a study on premenopausal women, researchers from Cedars-Sinai Medical Center in Los Angeles found that red wine is a nutritional aromatase inhibitor. It stops the conversion of free testosterone into estrogen, a risk factor for breast cancer. In other words, drinking red wine in moderation (one drink a day for women) may not pose a cancer risk. "For those who consume wine, I would suggest red wine," said the study leader in an interview. "For those who drink other alcoholic drinks, I would suggest switching to red wine."
Finally, a new study of more than 29,000 people from 52 countries shows what many studies have already shown: exercise has the power to reduce the risk of heart attacks—in this study, by up to 24%.
