Abstract:
Access to nutritious foods is limited in disenfranchised communities in the United States. Policies are beginning to focus on improving nutritious food access in these contexts; yet, few theories are available to guide this work. We developed a conceptual model of nutritious food access based on the qualitative responses of food consumers in 2 different regions of the American South. Five domains (economic, service delivery, spatial-temporal, social, and personal) and related dimensions of nutritious food access were identified. The conceptual model provides practical guidance to researchers, policy makers, and practitioners working to improve nutritious food access in communities.
