explores the health and economic implications of U.S. farm policy. Using a corn farm in rural South Dakota as his starting point, Johnson reviews the history of agricultural policies in America to understand how large-scale, industrial agriculture came to play such a large role in U.S. and world food production. He also discusses the role of agricultural policies in the on-going "food for fuel" debate, as well as the linkages between agricultural outputs and health outcomes. As the U.S. battles with a burgeoning epidemic of dietary disease - including some of the highest rates of obesity, diabetes, and hypertension in the developed world - it is especially important to understand where our food comes from and its relation to health, nutrition, and economic mobility. Ensuring America's health and well-being requires us to first return to the farm.
