NP 120 Part II: Gut-Brain Diet-Mental Health Connection: Exploring the Role of Microbiota from Neurodevelopment to Neurodegeneration

The foundational course in the growing field of nutritional psychology.


This course builds upon the foundation established in NP 120 Part I, Microbes in Our Gut: An Evolutionary Journey into the World of the Microbiota-Gut-Brain Axis and Diet-Mental Health Relationship (DMHR).

In this course, you’ll dive deeper into the intricate mechanisms interconnecting the microbiota-gut-brain axis with the diet-mental health relationship (MGBA-DMHR). You’ll learn how certain foods contain keys to unlocking these mechanisms, shaping our moods, emotions, psychological experience, social functioning, and even how they influence our dietary intake behavior. In this course, you’ll gain knowledge of the MGBA-DMHR’s intimate role in the development of psychological, psychiatric, neurodevelopmental, and neurodegenerative diseases. We explore myelination, synaptogenesis, neural plasticity, neurogenesis, hormones, neuropeptides, gut peptides, short-chain fatty acids, BDNF, and the guardians of the brain—the mighty microglia. These mechanisms operate within an intricate symphony to orchestrate and influence our psychological states, moods and emotions, social behavior, stress experience, resilience, cognitive processes, dietary intake behaviors, and mental health outcomes. 

Please note that NO PRACTICAL APPLICATIONS of nutritional psychology are provided in this course. That content will be covered in the NP 200 series.
