Traffic-light labels on menus: do they nudge us to eat better?
NCT ID NCT06923241
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether adding Nutri-score labels (A to E ratings) to restaurant menus, alongside calorie information, helps people pick healthier meals. Over 600 adults in Liverpool ordered from a menu with either calorie info alone or calorie info plus Nutri-score labels. Researchers measured how effective people thought the labels were and the nutritional quality of their food choices.

What this could lead to
If it works, this could show that simple front-of-pack labels help people make healthier choices when eating out.
What could go wrong
This is a small, completed study in one city, so results may not apply everywhere. It measures perceived effectiveness, not actual long-term health changes.
