Warning labels on soda: will they make us drink less sugar?
NCT ID NCT07294053
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 2 times
Summary
This study tests whether putting warning labels on sugary drinks helps people choose healthier options. Over 500 adults will shop in a mock store and see either a warning label or a plain label on drinks. Researchers will track how much sugar people buy and drink over four weekly visits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Added sugar warning label
- What this could lead to
- If it works, this could show that simple warning labels help people buy fewer sugary drinks, which may inform public health policies.
- What could go wrong
- This is a small, short-term study in a mock store, not real life. People may behave differently at home, and the effect might not last or lead to long-term health changes.
