In the United States, both industry and the federal government have worked to establish voluntary guidelines for how firms market food to children and to establish a threshold for the nutritional quality of foods marketed to children. The authors evaluate three US guidelines that deal with television advertising of breakfast cereals, which is both heavily advertised and a common meal item for children. They find that the majority of cereals advertised primarily to children from 2006-2008 do not meet any of the current and proposed self-regulatory nutrition guidelines, and that this is generally due to excessive sugar content. Further, children and adolescents are exposed to more advertising for products that do not meet the nutritional guidelines. We evaluate the extent to which each of the guidelines impacts advertising of cereals that are most viewed by children and purchased by households with children. The results provide insight for policy makers concerned with limiting the extent to which children see television advertising and ultimately consume unhealthy breakfast cereals.
