Social media is recognized as a crucial source of information about food and nutrition. Research shows
that while TikTok offers a substantial number of nutrition-related videos, the quality of the information
provided varies. The development of nutrition literacy is, therefore, only growing in relevance. Through
a quantitative content analysis of nutrition-related TikTok videos (n = 150), this
... [Show full abstract] study explores how infor
mation about nutrition is presented on the platform. More specifically, we analyze who discusses nutrition
on TikTok, which topics can be identified, and to the visibility levels of advertising. In terms of nutrition
literacy dimensions, the analyzed TikTok videos predominantly focus on capacities in preparing food,
snacking, and social or conscious eating. Thematically, the videos often cover recipes, cooking, and dietary
advice, showcasing both fresh and processed foods. However, the quality of food is seldom addressed,
and the same applies to household planning and food storage. Videos featuring snacks primarily depict
healthy snacking, with those involving unhealthy snacks more likely to include advertising. Finally, the
paper discusses opportunities and risks that nutrition experts may face when presenting nutrition-related
information on TikTok, and critically reflects on nutritional disinformation on the platform.
