Keys Battles America's Obesity

R+B star Alicia Keys is teaming up with Sesame Street character COOKIE Monster to tackle America's obesity epidemic.

In his new song, A COOKIE IS A SOMETIMES FOOD, furry blue creature Cookie Monster learns there are "anytime" foods and "sometimes" foods, and cookies are decidedly "sometimes".

DR ROSEMARIE T TRUGLIO, the longrunning TV show's vice president of research and education, says the Street also will introduce new characters, such as talking eggplants and carrots, and guest stars will address healthy activities - such as FALLIN' singer Keys talking and singing about physical activity.
