Michael Bloomberg

70, New York City

POSITION: Mayor

NOTABLE FOR: Using the bully pulpit to take local action on national food-related health issues. His push to ban sales of oversized sodas cannily turned attention toward portion size as a public health concern. The soda push followed two earlier measures: a ban on trans fats in restaurants in 2006 and mandatory calorie-posting on menus in 2008 (adopted nationwide by McDonald’s in September). Research is mixed on the effectiveness of calorie-posting, but the mayor got the city talking.
