Nutrition psychology is the psychological study of the relationship between dietary intake and different aspects of psychological health. It is an applied field that uses an interdisciplinary approach to examine the influence of diet on mental health.^[1] Nutrition psychology seeks to understand the relationship between nutritional behavior, mental health and general well-being. It is a sub-field of psychology and more specifically of health psychology, and may be applied to numerous related fields, including psychology, dietetics, nutrition, and marketing.^[1]

Nutrition psychology assesses how nutrition affects psychological functions, and how psychological choices and behavior influence nutrition and health.
