Learn how The Dietary Guidelines for Americans, a governmental description of what constitutes a nutritious diet, has become a political tool of the US Department of Agriculture. Listen to how the USDA operates under a large conflict of interest — they must maximize the sale of American farm products, mainly wheat and corn, while providing guidelines for what Americans should eat. This typically means that their definition of “nutritious” is crafted to coincide with what the farmers grow despite the negative impact on our health.
