Can Low-Income Americans Afford a Healthy Diet?

Abstract

Many nutritional professionals believe that all Americans, regardless of income, have access to a nutritious diet of whole grains, lean meats, and fresh vegetables and fruit. In reality, food prices pose a significant barrier for many consumers who are trying to balance good nutrition with affordability. The Thrifty Food Plan (TFP), commonly cited as a model of a healthy low-cost diet, achieves cost goals by relaxing some nutrition constraints and by disregarding the usual eating habits of the American population. Diet optimization techniques, when sensitive to cost and social norms, can help identify affordable, good tasting, nutrient-rich foods that are part of the mainstream American diet.
