David Wallinga, M.D of the Institute for Agriculture and Trade Policy, wrote an article showing the role of U.S. agriculture policy in promoting the overproduction of certain farm commodities like corn and soybeans. These cheap commodities have been converted into calorie-rich but nutrient-poor snacks, sweets and sweetened beverages that have led to an excess of daily calories for all Americans, children and adults alike. For that reason, Dr. Wallinga calls U.S. farm policy a “cheap calorie” policy. Source: http://www.iatp.org/
