Sugar shock: will warning labels make us skip the soda?
NCT ID NCT07570576
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This online study with 2,800 Hong Kong adults tests whether front-of-package warning labels about added sugar reduce people's intention to buy sugary drinks. Participants will choose a beverage in a simulated shopping task. The goal is to see if simple labels can guide healthier choices and help fight obesity.
