In the last 15 years or so, tremendous effort has been spent to map, measure, and mitigate so-called food deserts. Drawing on years of scholarship, the 2008 US Farm Bill defined a food desert as an ‘area in the United States with limited access to affordable and nutritious food, particularly such an area composed of predominantly lower income neighborhoods and communities’ (Title VI, Sec. 7527). Living in food deserts has been linked to poor health outcomes that include overweight/obesity and a suite of diet-related diseases including hypertension and diabetes (Olson and Holben 2002). Such outcomes are the fodder for considerable debate and research in public health circles.
