Telling kids how far to run to burn off the calories in a soda made them think twice.

Does the nutrition information on food labels impact your choices? Data on effectiveness of the labels is inconsistent. In a novel trial conducted on adolescents in low-income black areas, researchers from Johns Hopkins University found that when they labeled sugary drinks with information on how much physical activity would be needed to burn off the calories, it significantly reduced sales of those drinks and increased water consumption. This was compared to providing absolute calorie counts or calories as a percentage of recommended.
