Teens say TikTok food content shapes what they want to eat, but parents can help them navigate its influence

A recent study published in the Journal of Nutrition Education and Behavior reveals that TikTok food content significantly influences teens' food choices. The research, conducted by Adrianna N. Bell, Ph.D., RN, PHN, senior research consultant at Delta Consulting Group, involved four focus groups with 25 adolescents aged 15-16 from a midwestern high school.

Participants discussed their frequent exposure to various TikTok food content, including recipes, viral food trends, restaurant reviews, influencer promotions, "What I eat in a day" videos, and advertisements. The researchers found that visually appealing food presentation, user comments, and endorsements from influencers often increased the adolescents' interest in trying the featured foods.

While the participants generally perceived their parents as uninvolved in their TikTok use, they also indicated that parents played an important role in interrupting exposure to food-related content and facilitating critical conversations about food, bodies, influencers, and online health information. Parental involvement, such as encouraging family meals, engaging in shared activities, or having face-to-face interactions, led to a decrease in the time teens spent on TikTok.

Parents could also act as a protective buffer by questioning the credibility of diet- and body-related claims and reminding their adolescents that an influencer's body, lifestyle, and results might not be realistic or applicable to everyone. The study's findings could inform future nutrition education and media literacy efforts involving both adolescents and parents.

Further research is needed to assess how exposure to food-related TikTok content affects actual dietary intake and how parents can best support healthy social media use and eating behaviors.
