Sarah Corapi, in Why it takes more than a grocery store to eliminate a ‘food desert’ (2014), explains why grocery store interventions are only the first of many necessary steps to eliminate food deserts. In a PBS interview, Steven Cummins, professor of population health at the London School of Hygiene and Tropical Medicine, discusses the psychology behind healthy dietary habits, as well as the policy that is supposed to facilitate that in order to examine the various reasons why an affordable grocery store is insufficient on its own. In GlobeMed, we looked at the Englewood Whole Foods as a supermarket intervention; Cummins agrees with the model, but stresses the importance of considering the culture around shopping and eating food, too.
