Nutrition Labels as Visual Persuasion

As the U.S. government considers new labels on packaged food, students can analyze arguments about this visual communication.

The latest idea is to show large, front-of-package (FOP) labels, possibly without the numbers and percentages we’re used to seeing. Consumers would see information more easily, albeit with some interpretative descriptions (options shown here). The goal is for consumers to make healthier choices.

Students could research arguments about the change. For example, one study showed household reductions in sugar, fat, and sodium after Chilean policies mandated front-side labels. Tony the Tiger was banned from this “Frosties” (Frosted Flakes) box. The Food and Drug Administration also describes focus groups and experimental studies in favor of the change.

The food industry argues that FOP labeling won’t have the desired effect, removes responsibility from consumers, and could infringe on products’ trademarks because of changes to the packaging. One older study showed mixed results of front-of-package labeling, including in a “halo effect” for “vice products,” for which any label—even one showing excessive sugar—made the product look more credible. Students will find more research on both sides and might consider how new weight-loss drugs could affect consumer choice.
