Background/Objectives:
The connection between nutrition and mental health has become a point of growing interest. In response, nutritional psychiatry research has emerged as a field dedicated to understanding these interactions. A bibliometric analysis was conducted to map the growth and trends in this area, providing insights into its evolving scope and key research contributions.
Methods:
A literature search was conducted within the Web of Science Core Collection. Data analysis was performed using the result analysis and citation report options of Web of Science as well as the visualization software VOSviewer (Version 1.6.20).
Results:
A total of 31,556 articles on nutrition and mental health were published from 2000 to 2024 across various WoS categories, mainly in "Psychiatry", "Public, Environmental & Occupational Health", and "Nutrition & Dietetics". The most prolific research groups are based in North America. Recent publications mainly cover seven clusters: (1) public health and social factors, (2) interventions and biological mechanisms, (3) the health of the elderly, (4) nutrition-related illnesses, (5) lifestyle behavior, (6) observational studies, and (7) pregnancy and the postpartum period.
Conclusions:
In view of the increasing research activities and growing allocation of resources in nutritional psychiatry research, it is important to define research priorities in close collaboration with service users and stakeholders. Research should be approached in a holistic manner through multidisciplinary research consortia to ensure comprehensive and impactful outcomes.
