How About Another Cup?

Premium

Coffee seems to be good for more than just keeping sleepy people awake. A new study published in Cancer Epidemiology, Biomarkers & Prevention shows that women who drink four or more cups of coffee a day have a lower risk of developing endometrial cancer than women who drink less than one cup a day, reports Bridget Kuehn at the [email protected] blog. The team analyzed data from more than 67,000 women between the ages of 34 and 59 and determined that there were 5.6 cases of endometrial cancer per 10,000 person years among women who drank less than one cup of coffee a day, compared to 3.5 cases per 10,000 person years among heavy coffee drinkers, Kuehn says. "After adjusting for multiple variables, the researchers found risk of endometrial cancer among the heavy coffee drinking group was 25 percent less than those who drank little, if any," she adds. This reduction occurred regardless of the coffee's caffeine status and wasn't seen in tea drinkers, indicating something in the coffee other than caffeine may be behind this effect. The researchers also said that adding cream and sugar to a cup of joe may counteract some of the benefits.
