37, London, England
POSITION: Superstar TV chef
NOTABLE FOR: Using star power to fight the good-food fight. Oliver is a superb performer with a sunny disposition and deep cooking chops. His Feed Me Better school-lunch campaign turned him into something of a saint in the U.K. Over here, the second season of Food Revolution ended in a victory when the Los Angeles County School Board agreed to remove flavored milk from school menus. But he didn’t stop there: His mobile kitchen toured L.A. this summer, teaching kids the ABCs of healthy cooking.
