Color-Coded labels on delivery apps could nudge healthier eating
NCT ID NCT07423845
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed online trial tested whether adding Nutri-Score labels (A to E, like a nutrition grade) to delivery app menus helps people choose healthier meals. 870 adults who regularly use food delivery apps made hypothetical meal choices in a simulated app. The study compared three groups: no labels, calorie labels plus Nutri-Score, and Nutri-Score with extra educational info. The goal was to see if the labels improve the nutritional quality of selected meals.

Active substance
Nutri-Score labelling (a color-coded nutritional label on menus)
What this could lead to
If it works, this could show that simple front-of-pack labels like Nutri-Score help people make healthier choices when ordering food online.
What could go wrong
This was an online simulation, not a real ordering situation. People may behave differently when actually spending money and eating. The results may not apply to everyone.
