Samenvatting

This thesis explores how food-related content on social media platforms like TikTok and Instagram influences the dietary behaviour of Dutch adolescents aged 15–18. Using both survey data and a focus group, the study reveals that emotionally engaging content, influencer promotions, and viral trends significantly impact food choices and perceptions. Statistical analyses, including Chi-Square and Spearman’s Rho tests, show that emotional responses are meaningfully linked to adolescents’ eating behaviour. Based on these insights, the Food Boost Truck was developed, an innovative school-based intervention that combines social media engagement with improved access to healthy food.
