Click & Pick Study

A Longitudinal, Randomized-Controlled Experiment of Healthy Food Policies in Online Retail Settings

Sponsor

University of Pennsylvania

Enrollment

300 participants

Start Date

Feb 1, 2026

Study Type

INTERVENTIONAL

Conditions

Chronic Disease

Summary

Unhealthy diets significantly contribute to major preventable chronic diseases including type 2 diabetes, obesity, heart disease and stroke, which disproportionally impact racial/ethnic minority groups and those with lower income \[1-3\]. Although taxes and warning labels targeting sugar-sweetened beverages (SSB) have been successful at shifting behavior \[4-7\], there are many other ultra-processed food products that contribute to unhealthy diets \[8\]. What is less well-known is whether a suite of healthy food policies that are expanded to target a range of ultra-processed foods can shift dietary choices and intake in meaningful ways. Our research team's long-term goal is to identify and understand the degree to which combinations of healthy food policies can improve nutrition security and reduce nutrition-related diseases.
