The Politics of Big Soda

Soda contributes to poor dental hygiene, obesity and type-2 diabetes. How did products which are essentially nothing more than sugar and water become multi-billion dollar industries while driving up health care cost of governments around the world? Marion Nestle, Paulette Goddard Professor of Nutrition, Food Studies and Public Health at New York University takes on this issue in her latest book "Soda Politics: Taking on Big Soda (And Winning)." We speak to her about soda taxes, marketing practices of Big Soda as well as how soft drink makers are responding to the overall decline in soda consumption worldwide.
