Nutritional quality at fast-food restaurants still needs improvement

A new study finds that fast food restaurant menus have only modestly increased nutritious offerings over a 14-year period, with most restaurants failing to meet optimal nutritional quality scores. Despite some improvements, the overall nutritional quality score remains below that of the average American diet.
