New research suggests that among postmenopausal women, those who drank sugar-sweetened beverages like soda were more likely to develop estrogen-related type I endometrial cancer than those who avoided sugar-sweetened beverages. The study looked at data from 23,039 postmenopausal women who reported dietary intake, demographic information, and medical history as part of the Iowa Women’s Health Study. Sugar-sweetened beverage consumption patterns of the women were categorized into quintiles, ranging from no intake (the lowest quintile) to between 1.7 and 60.5 servings a week (the highest quintile). The researchers reported 506 type I, and 89 type II endometrial cancers cases among the women between 1986 and 2010.
