About the ENP
A trusted guide to nutritional psychology terminology
Nutritional psychology examines how dietary patterns, nutrients, food-related behaviors, and psychological factors interact with mental health and well-being. Launched by the Center for Nutritional Psychology in 2024, the Encyclopedia of Nutritional Psychology defines the terms, mechanisms, processes, and research areas shaping this growing field.
Created for students, educators, researchers, healthcare professionals, and curious readers, the ENP includes hundreds of clear, research-informed entries. Content is written and regularly updated by contributors across relevant scientific disciplines, with new entries and major revisions reviewed by the CNP Encyclopedia Editorial Board before publication.
The encyclopedia helps readers understand terminology and foundational concepts. For deeper exploration of the studies behind those concepts, visit the Nutritional Psychology Research Library .
