Host Harry Kreisler welcomes writer Michael Pollan (In Defense of Food, Food Rules) for a discussion of the agricultural industrial complex that dominates consumer choices about what to eat. He explores the origins, evolution and consequences of this system for the nation's health and environment. He highlights the role of science, journalism, and politics in the development of a diet that emphasizes nutrition over food. Pollan also sketches a reform agenda and speculates on how a movement might change America's eating habits. He also talks about science writing, the rewards of gardening, and how students might prepare for the future.
