Summary
This study aims to evaluate whether Ultra-Processed Food (UPF) warning labels on social media posts improve consumer understanding and influence purchase intentions among teens and young adults. Participants aged 13-29 in the United States will be recruited and randomized into two groups: a control group (no label) and an intervention group (UPF warning). Participants will view social media posts featuring UPFs with or without warning labels and respond to survey questions following each post.
