Findings
In this randomized clinical trial of 7945 adults, participants exposed to green (“choose often”), single traffic light, physical activity calorie equivalent, or nutrient warning labels selected 28 to 39 fewer calories from beverages and 13 to 18 fewer calories from snacks than participants exposed to calorie labels, which were statistically significant reductions that were similar across the 4 interpretative labels. Effects did not differ by participants’ education level.
