Interoception is one of the six elements characterizing the field of Nutritional Psychology. Interoception plays a significant role in developing our understanding of the Diet-Mental Health Relationship (DMHR). Referred to as “the eighth sense,” Interoception is our perception of the internal physiological state of our body. Interoception pertains to the receiving, encoding, and representation of internal bodily signals in the brain, as well as their perception (Ceunen et al., 2016). Interoception encompasses the non-conscious bodily signals we experience, and our conscious perception of them. NP 110: Introduction to Nutritional Psychology Methods includes curriculum in Diet and Interoception.
