App-tastic eating: phone tool tries to nudge us toward greener plates

NCT ID NCT06833736

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested whether a smartphone app can help working adults eat more plant-based foods and less meat. 147 participants were split into three groups: one with no app, one with the basic app, and one with an enhanced app offering recipes and tips. The main goal was to see if people would actually use the app and find it helpful, not to prove health outcomes.
