Behavioral Economics to Implement Nutrition Ranking in Food Pantries

January 29, 2026 updated by: Anne N. Thorndike, MD, MPH, Massachusetts General Hospital

Behavioral Economics to Implement a Traffic Light Nutrition Ranking System in a Network of Food Pantries

The goal of this randomized controlled trial is to test whether using behavioral economic strategies to promote healthy food choices on a food bank's online ordering platform increases the use of the traffic light nutrition ranking system and increases healthier food selections by the food agencies (e.g., food pantries) who use the food bank.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will use behavioral economic strategies to promote utilization of traffic-light nutrition ranking in the Greater Boston Food Bank (GBFB) order system to improve the dietary quality of food ordered by GBFB agencies. Supporting Wellness at Pantries (SWAP) is a program to guide both traffic light labeling for use on ordering platforms and pantry shelves, as well as food pantry layout to inform clients and encourage healthy food choice.This study is a collaboration with the Greater Boston Food Bank (GBFB) to test BE strategies (choice architecture, framing, social norms) for implementation of an evidence-based intervention (traffic light nutrition ranking, SWAP). We will determine if behavioral economic interventions on the GBFB online ordering platform increase agencies' use of traffic light nutrition labels when placing orders and increases their healthy food orders. We will conduct a 12-month randomized controlled trial comparing agencies' ordering experiences and outcomes with the current user interface (control) to a "SWAP-enhanced" user interface (intervention). All GBFB partner agencies will be randomized to see either the control or intervention interfaces when they log on to ShopGBFB, GBFB's online food ordering platform. In addition, intervention group agencies will receive monthly emails from GBFB about SWAP labeling, such as why common items receive certain rankings (e.g., canned green beans will have a yellow label if there is added sodium) and common misunderstandings people have about SWAP labels (e.g., explaining why all chicken items do not get the same SWAP ranking). At the end of 12 months, agency staff will complete a survey about their online ordering experiences at GBFB. In the next phase, the SWAP-enhanced ShopGBFB interface will be updated, adapted, and implemented for all 364 agencies that place orders. Agency ordering outcomes will be monitored for 12 additional months.

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Food agencies that order food from the Greater Boston Food Bank (GBFB) online ordering platform.

Exclusion Criteria:

  • Food agencies that do not order food from the GBFB online platform within 2 months of the start of the study.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Behavioral economics-enhanced user interface
Food agencies will see the behavioral economics (BE)-enhanced interface by default; food items will be sorted with green-labeled items listed first, followed by yellow, then red. If users search for a specific item type (e.g., chicken) the results returned for that item type will also be sorted so that green-labeled items are listed first. At any time during the ordering episode, users will have the option to switch from the BE-enhanced default to an alternate sorting or filtering choice, such as alphabetical or cost. Users will be shown the percent of items (by weight) that are labeled green in a prominent location on the ordering screen. The percent green-labeled items in the order will appear alongside messaging reporting the average percent green-labeled items ordered by GBFB pantries that rank in the top 10% based on this metric. Agencies will receive monthly emails from GBFB about SWAP, describing why common items receive certain SWAP rankings (e.g., item is yellow vs green).
Behavioral: Behavioral economics-enhanced user interface
The intervention changes the ordering platform visible to food agencies using behavioral economics strategies to promote healthier food choices.
No Intervention: Usual user interface
When agency staff log on to the food bank platform, by default, foods are listed in alphabetical order. If they wish, users can change how items are sorted or filtered using pull-down menus and check-boxes, including the ability to have items sorted or filtered based on traffic light labels. As orders are created, an information section at the top of the page is updated with details on the order weight and cost. Agencies will not receive emails about SWAP.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Healthy food agency orders from the food bank
Time Frame: 12 months
This will be the change from baseline to 12 months in the percentage of foods ordered (by weight) that have green labels.
12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Proportion of agencies that ever used the traffic light label sorting or filtering when ordering from the food bank
Time Frame: 12 months
This outcome will be the proportion of agencies in the intervention vs. control group that report using the traffic-light sorting/filtering when making orders during the 12 month intervention period.
