Summary

This study will test whether putting warning labels on social media posts about ultra-processed foods helps teens and young adults understand what they are eating and whether they would buy those products. About 1,000 people aged 13-29 in the U.S. will view Instagram posts with or without warning labels and answer survey questions. The goal is to see if these labels can improve consumer awareness and influence purchase intentions.
