The next month the women who drank red wine were told to drink white wine instead. The white wine drinkers were told to drink red wine. The researchers found that the women who drank red wine had lower levels of the female hormone estrogen than the white wine drinkers. Estrogen levels are known to increase the growth of cancer cells in the body.
Glenn Braunstein helped to prepare a report on the study. He said red grapes have chemicals that are not found in white grapes. He said the study suggests that these chemicals may help to lower the risk of breast cancer.
The report was published in the Journal of Women’s Health. Both Dr. Braunstein and study organizer Chrisandra Shufelt called for larger studies to measure the safety and effectiveness of red wine in reducing breast cancer risk. They said other recent studies suggested that even small amounts of alcohol may generally increase the risk of breast cancer in women.
Researchers at Harvard University carried out one such study. It found that women who drink four small glasses of wine a week increase their risk of breast cancer by fifteen percent.
Many other studies have examined the harmful effects of alcohol use on the body. Medical experts say the deciding issues are how much alcohol you drink, and how you drink it. For example, experts say having three drinks in one day is not the same as having one drink a day for three days.
