Fried chicken and fresh apples: racial segregation as a fundamental cause of fast food density in black neighborhoods.

As rates of overweight and obesity have surged in the US, researchers have turned attention to the environmental context of diet and disparities in access to healthful foods. Despite evidence that Black neighborhoods are disproportionately exposed to fast food, few explanations have been advanced to illuminate explanatory mechanisms. This paper contends that race-based residential segregation is a fundamental cause of fast food density in Black neighborhoods. Segregation's effects on population and economic characteristics, physical infrastructure, and social processes work in tandem to increase the likelihood that Black neighborhoods in urban environments will bear a disproportionate burden of fast food restaurants.
