Does a product’s packaging
influence you? As it turns out, images
shown on food products just might make more of an impact than you know. A recent series of studies discovered that
people eat a larger portion of cake when a frosted
cake is shown on the cake mix box. In one
of the studies, the image of a cake covered in frosting encouraged participants
to consume 135% more calories than the serving size. A subsequent study included a cake mix box with
the phrase, “frosting not included on the nutritional labeling.” These participants chose a more appropriate
and less caloric serving size.
Regardless of the type of food product,
many consumers automatically assume that the picture on the box reflects the
recommended serving. In fact, the food
packaging likely influences consumers’ portion sizes more so than the printed
serving size. Researchers collectively
believe that when a generous portion is displayed on a product’s packaging, it
causes consumers to overestimate on serving size. To avoid misleading consumers, the
researchers urge manufacturers to include a phrase reminding their customers that
any additional items shown are not included in the recommended serving size.
