In nutritional psychology, interdisciplinary refers to intentionally integrating the psychological sciences (e.g., cognition, emotion, behavior, psychosocial functioning, perception, interoception, mental health) with the nutritional sciences (e.g., nutrients, dietary patterns, eating behavior, metabolism) into a coherent, shared framework. Rather than treating “nutrition” and “mental health” as separate silos, the field organizes evidence across these disciplines to study the bidirectional relationships between dietary intake and psychological processes and outcomes.
