1:49 AM MYT CHICAGO, Dec. 10 (Xinhua) -- A study of the University of Michigan (UM) School of Public Health and University of California (UC) Davis found that placing warning labels on beverage dispensers helped reduce consumption by nearly 15 percent. The researchers placed warning labels on beverage dispensers at a U-M cafeteria for one semester in 2019. The labels were bright yellow with a large triangle and exclamation mark stating, "Warning: Drinking beverages with added sugar(s) contributes to type 2 diabetes, heart disease, and tooth decay." Two other cafeterias on campus located geographically distant from the cafeteria with the labels served as control sites and had no warning labels.
