“…As a researcher, if ‘food desert’ is something policymakers hear and want to do something about, I’m in support of it. But as a community member, it’s another negative thing about the place where I live... It’s not the need that brings in the resources. There’s got to be that ‘and’: There’s a need and there’s an economic opportunity." - Angela Odoms-Young, an instructor in UIC’s College of Applied Health Sciences
