From One City to Many: Scaling Best Practices for Healthy Corner Stores

Project Overview:

This GFI-led research project, funded by the Patrick J. McGovern Foundation, was a collaboration with DC Central Kitchen (DCCK) and Partnership for a Healthier America (PHA) to evaluate DCCK’s Healthy Corners program, a unique and powerful model to advance healthier food choices in urban corner stores.

This project explored how to adopt and replicate the model of DC Central Kitchen’s Healthy Corners – which delivers affordable fresh produce to corner stores in low-income DC neighborhoods – in other communities. Over one year, the project team conducted community informed food systems assessments in two distinct regions where PHA has a strong presence: Indianapolis, Indiana and the Mississippi Delta.  

Approach: 

As the partnership worked with communities to assess whether aspects of DCCK’s model would benefit them, we facilitated a participatory process that centered local knowledge and priorities. This approach reveals root causes and systemic vulnerabilities, not just surface-level symptoms, enabling stakeholders to assess interventions with respect to long-term resilience. It also established a community-defined framework for measuring progress toward shared goals, providing clear accountability while maintaining the local buy-in essential for sustained change.  

We used three specific methods within systems science approaches as a part of this project:

Community-based System Dynamics

A series of participatory workshops with stakeholders from different sectors to create systems map identifying barriers and leverage points for health food access.

Stakeholder Network Analysis

Surveys to identify stakeholders in the current food system, map their coordination and information flow; and pinpoint leaders critical to future interventions.

Community-Led Pilots

Site-specific programming to establish shared goals and advance nutritious, resilient food systems.

Key Learnings:

  • Programs must reflect how each community already accesses, purchases and consumes food – with community members involved from start to finish.
  • Local food systems are pivotal: access to healthy food is directly linked to support for local farmers, financial stability and community pride.
  • Community well-being extends beyond physical health to include financial stability, emotional health, belonging and trust – and history shapes how these are built.
  • Shared infrastructure – distribution, storage and equipment – is foundational to successful local systems.

 

 

New Resource: 
Healthy Corners Practice Manual

A valuable product of this project is DC Central Kitchen’s first-ever Healthy Corners Best Practice Guide, developed in Summer 2025. Drawing on real-world experience and years of program evaluation, this plain language manual helps practitioners and advocates across the country to replicate and adapt the Healthy Corners Model.  GW and the rest of the collaborative team continues to disseminate the resource through national conferences and partner networks.
