Decoding Health Professionals' Attitudes and Perceptions Towards Plant-Based Nutrition: A Narrative Review

Background/Objectives: The ongoing obesity epidemic remains a significant public health challenge in the U.S. Nearly one-third of adults are overweight, and nearly half of the population (42.4%) are obese. These conditions, driven by poor and unsustainable diets, are major risk factors for several chronic diseases, including heart disease, which continues to be the leading cause of death in the country. This review aims to examine existing research on health care professionals' attitudes and perceptions of plant-based nutrition and explore how this knowledge can be utilized to promote the adoption of plant-based diets (PBDs) among Americans as an alternative to the standard American diet. Methods: PubMed and Web of Science databases were searched in April, 2024. Out of the 151 articles identified, 27 were deemed eligible and included in the narrative review. Results: Nine key themes were identified as major influences on the attitudes and behaviors of health professionals regarding PBDs. These themes were mapped with the domains of the Theoretical Domains Framework (TDF) to stratify key enablers and barriers to implementation of PBDs in routine care for patients. Conclusions: Key barriers to incorporating plant-based nutrition into routine care include time constraints, limited educational resources, insufficient skills, lack of multidisciplinary collaboration, and inadequate professional training. Access to evidence-based research summaries, clear guidelines, ongoing professional development, and other relevant educational resources were identified as facilitators of successfully integrating PBDs into everyday practice.
