Mapping the research landscape on food and nutritional literacy: a bibliometric analysis

Purpose The study aims to analyze research trends and hotspots in the field of food and nutrition literacy to inform evidence-based policymaking, and promote the health and well-being of the general population. Design/methodology/approach The Scopus database was used to retrieve relevant research articles using specific keywords related to food or nutritional literacy. Findings The analysis included 341 research articles, predominantly authored by scholars from the USA. Growth pattern of publications indicated recent evolution of the food and nutrition literacy concepts. The research hotspots identified included the development of tools to assess literacy, assessing food and nutritional literacy competencies among school children and adolescents and finally, cross-sectional survey studies on various international cultures to assess food and nutritional literacy. The top cited articles in the field focused on the operational definition and difference between nutrition literacy and food literacy. Research limitations/implications The findings underscore the need for comparative studies across countries, and advocacy for policy change to advance food and nutrition literacy among school students and vulnerable populations. Practical implications Policymakers, public health officials and practitioners can use the research findings to inform the development of evidence-based policy frameworks and interventions aimed at addressing the gaps in food and nutrition literacy. Social implications By promoting and advocating for policy reforms, and addressing gaps in food and nutrition literacy, the study contributes to fostering global future public health. Originality/value The study provides insights into the evolving research landscape on food and nutrition literacy, emphasizing the growing scholarly interest in understanding the concept and its public health impact.
