This document discusses food deserts and the food system context in New York City neighborhoods like Central and East Harlem and the Bronx. It defines food deserts as areas without access to affordable, healthy food options and instead having fast food restaurants and convenience stores. While the USDA map does not identify many food deserts in NYC, studies have shown these neighborhoods have higher obesity rates due to an overabundance of bodegas and fast food but a lack of supermarkets and healthy options in bodegas and restaurants. The document examines how the food system can influence individual nutrition and health.
