Supporting Wellness at Pantries (SWAP) is a PSE intervention designed to promote the donation and selection of nutritious foods throughout the charitable food system. The program is based on the theory that categorizing food using simple, intuitive labels and communicating this information at each decision point while food travels through the system (donor, food bank, food pantry, & client) has the potential to transform the policy, systems, and environment of food banks and food pantries. SWAP consists of a suite of tools for food banks and food pantries to rank their inventory using a traffic light nutrition system. SWAP was developed in 2016 and revised in 2020 to align with and use the Healthy Eating Research (HER) Nutrition Guidelines for the Charitable Food System. These guidelines place foods into 11 categories and assign green=choose often; yellow=choose sometimes; and red=choose rarely based on levels of saturated fat, sodium, and added sugars. SWAP can be used as an intervention in multiple levels of the charitable food system to promote food justice and health equity.

Intervention Reach and Adoption

SWAP targets food pantries and similar food programs that serve adult populations of all racial and ethnic backgrounds. SWAP's traffic light system can be understood regardless of English proficiency or literacy level. In recognizing that many food pantries may not have computers or Wi-Fi access, SWAP includes posters and handouts so volunteers can rank food with or without the use of technology. To date, over 200 food pantries have implemented SWAP, and over 30 food banks are using the HER Nutrition Guidelines with SWAP. Once SWAP is implemented, volunteers and staff continue to rank foods, and new staff or volunteers can be trained by current staff/volunteers.

Intervention Components

Key intervention components for food pantries include training staff and volunteers to accurately rank food using SWAP, organizing shelves and ensuring the proper SWAP label is used for each item using shelf tags, and displaying SWAP posters so clients understand what each ranking means. Pantry staff use SWAP to solicit and order healthier food. Timing for implementation depends on the pantry and their capacity. Pantry staff can use creativity to design the layout and shelving with SWAP signage. For food banks, key components to implementation include training staff to rank food, ranking food using SWAP, entering SWAP rankings into the inventory system, and displaying those rankings when pantries order from the food bank. Implementation timelines vary and can range from two months to one year or longer. Food banks that have nutrition policies and strong leadership support often have the shortest timelines.

Evidence Summary

In the development of SWAP, focus groups of pantry staff/volunteers provided feedback on perceived benefits and barriers by using stoplight ranking to promote healthy foods. Then a sample of 230 clients were surveyed to learn about food preferences when at food pantries, the results of which showed demand for nutritious food.  SWAP was pilot tested with 6 Connecticut pantries and feedback informed the messaging and implementation. In the 6 pilot pantries, a brief survey with food pantry staff and volunteers was conducted approximately 3 months after SWAP was implemented to measure their satisfaction with SWAP, ease of use, and perceived satisfaction among clients. The survey also included open-ended questions to gather qualitative feedback about suggestions for improving the system. Overall, the reaction to the new SWAP system was very positive and survey results helped develop additional training materials for future pantries. 

The HER Nutrition Guideline expert panel was purposefully created to include 50% nutrition experts and 50% experts/practitioners in the charitable food system. Then a Feeding America taskforce reviewed, provided feedback, and adopted the guidelines. SWAP was then revised to completely align with the HER Nutrition Guidelines.  

Research on SWAP shows that the availability of healthy food increases significantly when nutrition ranking is used, and it works at every level of the charitable food system. Food pantries order more nutritious food from the food bank when the food bank ranks their inventory using SWAP and displays that information in their online ordering system. Among the largest changes were increases in orders of fresh produce, brown rice, low-fat dairy and low-fat meats and decreases in orders of sugary juice drinks, canned fruit with added sugar, higher fat dairy and higher fat meats. After food pantries implement SWAP, the nutritional quality of their inventory supply improves, and food pantry clients selected more green items and fewer red items than before implementation.

Evaluation Indicators

Based on the SNAP-Ed Evaluation Framework, the following outcome indicators can be used to evaluate intervention progress and success.

 Readiness and Capacity - Short Term (ST)Changes - Medium Term (MT)Effectiveness and Maintenance - Long Term (LT)Population Results (R)
Environmental Settings MT5 
Sectors of Influence   
  • MT5a: Number and proportion of sites that make at least one change in writing or practice to expand access or improve appeal for healthy eating  
  • MT5f: Total potential number of persons who encounter the improved environment or are affected by the policy change on a regular basis and are assumed to be influenced by it. 
Evaluation Materials

Evaluation materials include: 

  • Survey of client food preferences for planning to implement SWAP and understand client preferences. 
  • Survey of client feedback and satisfaction to assess client knowledge and attitudes around SWAP. 
  • Inventory snapshot worksheet for pantries to record inventory rankings and change over time. 
  • Inventory reporting for food banks to run reports, set benchmarks, and display change in their inventory nutritional quality over time.
