Globally, 75% of adolescents do not meet recommendations for fruits and vegetables (F&V) consumption. This study investigated drivers of F&V choices among adolescents in Benin and identified barriers and facilitators to modifying F&V consumption. We conducted 16 focus group discussions (FGDs) with 126 adolescents and 5 semi-structured school observations in December 2024. FGDs were purposively chosen to explore variation by region (north/south), school location (urban/rural), adolescent age (12 to 15 years/16-18 years) and gender (boys/girls). Inductive and deductive thematic content analysis was performed using Atlas.ti. Findings showed that adolescents perceived a healthy diet as one composed of meals providing nutrients and strength, and including F&V. At home, adolescents mentioned eating staples and other vegetables more than other food groups. The foods adolescents reported typically eating at school varied by age, gender, and location. The primary categories of factors that influenced adolescent F&V choices were: intrapersonal (knowledge related to healthy eating and the nutrition and health benefits of F&V, taste preferences, and health prioritisation), socio-cultural (family and peer influences), and food environment (low availability, low affordability, convenience, and desirability). DFC factors were consistent across adolescent age, gender, and location. Multiple, dynamic, and multilevel factors influence adolescent F&V choices. Interventions that simultaneously address multiple barriers and involve family and peers are likely to be more successful in promoting F&V consumption and healthy diets than interventions only addressing individual barriers.
