Once in 5 years, the American Cancer Society publishes its updated guidelines on nutrition and physical activity in the context of cancer prevention [1]. Among the detailed advice is the following quote: ‘Limit consumption of sugar-sweetened beverages such as soft drinks, sports drinks, and fruit-flavored drinks.’ How this general phrasing relates to specific cancer types is discussed below, and a recent study serves as a good starting point [2]. The investigators evaluated the impact of dietary intake of sugary foods and beverages, as well as added sugar and total sugar on endometrial cancer risk in a population-based, case-control study, including 424 cases and 398 controls. Participants completed an interview and food frequency questionnaire and provided self-recorded waist and hip measurements. Women in the highest quartile of added sugar intake had significantly increased endometrial cancer risk (OR 1.84, 95% CI 1.16–2.92). Among women with waist-to-hip ratio ≥ 0.85, risk was significantly higher for the highest versus lowest tertile of added sugar intakes (OR 2.50, 95% CI 1.38–4.52). The association with added sugar also became stronger when analyses were restricted to never users of hormone replacement therapy (OR 2.03, 95% CI 1.27–3.26, for highest versus lowest tertile). There was little evidence of effect modification by body mass index or physical activity.
