Summary
Research on ultra-processed foods and neuropsychiatric disorders is growing rapidly. Brazil and the US lead, but international collaboration needs strengthening to advance understanding of diet and mental health links.
Area of Science:
- Nutrition Science
- Neuroscience
- Public Health
Background:
- Ultra-processed foods (UPFs) are increasingly linked to adverse health outcomes.
- Neuropsychiatric disorders represent a significant global health burden.
- Understanding the nexus between UPFs and mental health is crucial for public health interventions.
Purpose of the Study:
- To analyze the academic landscape of research on ultra-processed foods and neuropsychiatric disorders.
- To identify trends, collaboration patterns, and key thematic areas from 2019-2024.
- To assess the current state of scientific production in this emerging field.
Main Methods:
- A scientometric analysis following RAMIBS guidelines was conducted.
- Scopus database was searched for relevant publications (2019-2024).
- Data analyzed using SciVal, R Studio, and Bibliometrix for bibliometric indicators and Bradford's Law.
Main Results:
- 53 documents were identified, showing a 24.57% annual growth rate.
- Brazil and the United States were the most productive countries, with 18.87% international collaboration.
- Key journals include "Nutrients" and "Preventive Medicine"; keywords highlight diet, obesity, and mental health.
Conclusions:
- Research on ultra-processed foods and neuropsychiatric disorders demonstrates sustained growth.
- Brazil and the US are leading contributors, with "Nutrients" as a primary dissemination journal.
- Limited international collaboration presents an opportunity for enhanced global research networks.
