Sugary Beverage Consumption Ups Diabetes Risk

A recent study published in Diabetes Care analyzed the association between reduced consumption of sugary beverages (including sugar-sweetened beverages and 100% fruit juices) and artificially sweetened beverages (ASBs) and type 2 diabetes (T2D) risk. Data were collected from female patients in the Nurses’ Health Study (1986–2012; n = 76,531) and the Nurses’ Health Study II (1991–2013; n = 81,597), and male patients in the Health Professionals’ Follow-up Study (1986–2012; n = 34,224). Food frequency questionnaires administered every four years were used to assess changes in daily beverage consumption (8 oz.). The association between hazard ratios for diabetes and beverage consumption changes was determined using multivariable Cox proportional regression models. Outcomes from all three groups were collectively assessed using an inverse variance-weighted, fixed-effect meta-analysis. Final analysis included 2,783,210 person-years of follow-up. A total of 11,906 incident T2D cases were recorded. In adjusted analyses, increasing total sugary beverage intake by more than half a serving daily over a four-year period increased T2D risk by 16% (95% CI, 1%–34%) in the subsequent four years. Increased ASB consumption of the same proportion was associated with an 18% increased risk (95% CI, 2%–36%). Patients who replaced one daily serving of sugary beverage with water, coffee, or tea reduced their T2D risk by 2–10%, although this association was not observed in ASB consumption.
