Cereal is more heavily advertised to kids than any other packaged-food category. And according to Nielsen and other data analyzed by Yale's Rudd Center for Food Policy and Obesity, the least healthy cereals are the ones marketed most aggressively to children. The top 10 cereals that target kids are all brimming with sugar — most have nearly three teaspoons per serving. Of these cereals, General Mills' Cinnamon Toast Crunch does the most advertising on television to children, with 6- to 11-year-olds seeing an average of 82 commercials for the cereal in a 15-month period.
