"TikTok Made Me Do It": Teenagers' Perception and Use of Food Content on TikTok

This research explores how teenagers interacted with food-related TikTok content and how this influenced their eating behavior and practices. Using 186 surveys and five interviews, we show how teenagers think of healthy eating and what actions they took after being inspired by TikTok. We find that teenagers take inspiration from TikTok food content in different temporal stages, from immediately trying out new food items to long-term diet planning. We discuss potential design opportunities to support teenagers' social use of TikTok food content in online and offline contexts.
