The impact of dietary patterns and nutrient status on adolescent mental health and emotional well-being

Adolescence is a pivotal period of strong neurodevelopment combined with high emotional and psychological vulnerability. This review explores the integral relationship between dietary status and adolescent mental health outcomes, examining how systemic dietary patterns often shaped by socioeconomic factors influence the gut-brain axis. It summarises current evidence elucidating the bidirectional communication through which the gut microbiome influences the synthesis and regulation of key neurotransmitters (e.g., serotonin and dopamine) required for mood stabilisation. The paper highlights the importance of certain micronutrients, including omega-3 fatty acids, B vitamins, and magnesium in maintaining structural brain integrity and modulating stress responses. In contrast, it analyses the impact of western dietary patterns, which are abundant in refined carbs and sugar, on systemic inflammation and glucose dysregulation, both of which exacerbate mood instability and cognitive impairments. By identifying nutrition as a key, modifiable predictor of emotional resilience, this synthesis underscores the importance of pushing beyond traditional psychological treatment. It concludes by advocating for targeted, integrated nutritional intervention and public health strategies that promote adolescent mental well-being during this critical developmental stage.
