  "abstract": "Introduction A healthy diet is a crucial component for adolescents’ health and wellbeing. Current literature surrounding dietary intake and its effect on cognition, mental health and wellbeing has mainly focused on children, not adolescents. This review aims to synthesise findings from studies that explore the relationship between dietary intake and cognition, mental health and wellbeing in the adolescent population.Methods and analysis Electronic searches will date from 1 January 2000 to 7 October 2024 and will be conducted in CENTRAL, MEDLINE/PubMed, CINAHL via EBSCOHOST, ERIC, British Education Index, Child and Adolescent Studies, Education research complete, Psychology and Behavioural Sciences Collection, Social Policy and Practice Embase, and APAPsychINFO via OvidSP. Articles will be screened using defined inclusion and exclusion criteria and assessed for eligibility by five independent reviewers. Discrepancies will be reviewed by a third reviewer. The selection process of included articles will be reported by using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram. A narrative summary will be used to report and synopsise the extracted data.Ethics and dissemination This systematic review does not require ethical approval. The dissemination strategy for this review comprises peer-reviewed publications, public health conference presentations and providing a valuable reference for healthy-food interventions in school and community-based settings as well as identifying gaps in the current literature and informing policy and practice.PROSPERO registration number CRD42025633083.",
