The Role of Front-of-Package Nutrition Labels with and without Explanatory Videos on Parent and Child Food Choices.

The aim of this research was to determine whether parent/child pairs choosing products from a grocery aisle labeled with front-of-package (FOP) nutrition labels would make more healthful choices than pairs who viewed the same items without labels, and to determine the added value of viewing an explanatory video before choosing. In this experiment, 175 parent/child pairs chose USD 20 worth of packaged foods and beverages from a grocery aisle in a research laboratory and were randomly assigned to see products that either did or did not have 0-4-star FOP labels, with more stars indicating more healthful products. Among those participants with access to FOP labels, half were randomly assigned to view a 30 s video explaining the FOP labels before selecting foods. Participants who saw the explanatory video before selecting among products with FOP labels chose foods with significantly more stars than participants who saw the FOP-labeled products without the video; however, there was no significant difference in mean stars on selected products between the group that saw the videos and the control group that saw neither the video nor FOP labels. We conclude that explaining new FOP labels to consumers may be necessary for the labels to prompt more healthful choices.
