Is nutritional psychology a field situated within the psychological or nutritional sciences?

Nutritional psychology is considered an interdisciplinary field that sits at the intersection of psychology and nutrition—it is not exclusively part of either discipline. Its foundations and conceptual frameworks are rooted primarily in the psychological sciences but also incorporate evidence and methods from nutritional science, neuroscience, physiology, and related areas. In practice, nutritional psychology integrates psychological theories and research with nutritional science to examine how diet and psychological processes influence mental health and behavior.
