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 mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- menu labelling type (Nutri-score labels with calorie info vs. calorie info alone)
- 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.
