Background: A healthy diet is a crucial component for adolescents’ health and wellbeing as having a balanced nutritional intake during adolescence is essential for cognitive development as well as the prevention of health problems in adulthood. Current literature surrounding dietary intake and its association with cognition, mental health and wellbeing has mainly focused on younger children. Previous reviews have synthesised evidence on food consumption, dietary behaviour and nutritional interventions, and their relationship to cognition and mental health outcomes. However, there has not been a review conducted that examines these associations focusing solely on the adolescent population.
The aim of this study is to review and synthesise studies that explore the relationship between dietary intake and cognition, mental health and wellbeing in the adolescent population.
Methods: Electronic searches were conducted in CENTRAL, MEDLINE/PubMed, CINAHL via EBSCOHOST, ERIC, British Education Index, Child and Adolescent Studies, Education research complete, Psychology and Behavioral Sciences Collection, Social Policy and Practice Embase, and APAPsychINFO via OvidSP. This systematic review will be conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Title and abstracts are being screened by two independent reviewers, then full texts will also be assessed by two reviewers. A narrative summary will be used to report and synopsise the extracted data.
Results: 6715 records have been identified from the database searches, with 1790 duplicate records removed. 4925 records are currently being screened for relevance. Data extraction and synthesis is due to be completed in January 2025 and full results will be presented at the conference.
Discussion: The findings of this review will be a valuable reference to inform education prevention research as well as policy and practice aimed at improving nutritional intake and mental wellbeing in adolescents, as well as identifying gaps in the current literature.
