There won’t be any more candy, sugary cereal or fast food on TV with the morning cartoons. The Walt Disney Co. has become the first major media company to ban ads for junk food on its television channels, radio stations and websites, hoping to stop kids from eating badly by taking the temptation away. First Lady Michelle Obama called it a “game changer” that is sure to send a message to the rest of the children’s entertainment industry. Many foods, such as prepackaged lunches, fruit drinks, candy and snack cakes, won’t make the cut. The nutrition criteria were created by experts to reflect the government’s dietary guidelines. The company says it’s already working with major food companies to reformulate products so they can be advertised during children’s programming. Disney’s rules – which won’t take effect until 2015 – follow a proposal by New York Mayor Michael Bloomberg to take supersized drinks over 16 ounces out of convenience stores, movie theaters and restaurants, removing choices to try to influence behavior.
