Effects of wine on breast cancer related hormones

Washington: In a new study, scientists have compared the effects of red wine versus white wine on hormones related to the risk of breast cancer.

Aromatase inhibitors (AIs) prevent the conversion of androgens to estrogens, and could play a role in the development of breast cancer.

This study of 36 pre-menopausal women consisted of a cross-over intervention trial to determine if there were differences between red wine and white wine in their effects on AIs.

Subjects sequentially consumed eight ounces of red wine, followed by white wine (or vice versa), each beverage for a one-month period.

The investigators concluded that red wine, but not white wine, was associated with significant effects on some indices of estrogen metabolism, free testosterone and luteinizing hormone were increased, but no significant differences were noted in estrogen levels.
