One study from the nonpartisan Public Policy Institute of California found that poor neighborhoods had nearly twice the amount of convenient stores and fast food restaurants as wealthier areas. While that finding may not come as a surprise, the study also found that the poor neighborhoods also had access to more large supermarkets and chain grocery stores per square mile.
"It is always easy to advocate for more grocery stores, Kelly D. Brownell, director of Yale Universitys Rudd Center for Food Policy and Obesity, who was not involved in the studies, told the Times. "But if you are looking for what you hope will change obesity, healthy food access is probably just wishful thinking."
In a separate study for the RAND corporation, Dr. Roland Sturm found that childrens proximity to food had no bearing on their health, despite what food desert activists had previously suggested. In his research, students weight and the types of food they ate were unaffected by the supermarkets or restaurants around them.
