In 1990, new legislation charged the FDA to develop a labeling program that consumers could use to inform their dietary decisions. Three constraints governed label development. First, complex information had to be conveyed simply, in a way consumers of low-level literacy could understand. Second, poor printing quality demanded simple letterforms and graphic styling: sophisticated graphic devices and color could not be used. Finally, space was at a premium. Manufacturers who jealously guard valuable label space lobbied to have the required nutritional chart occupy the smallest possible portion of the total food label.
