An Evolutionary Journey into the World of the Microbiota Gut-Brain Axis and the DMHR
My brain is full of so much information about how mental health can be impacted by the gut and how much our diet impacts our gut. I can't wait to use this information to help me in my own life with my gut issues, and to help my clients with their health and mental health. —NP 120 Part I Learner
Nearly 2,500 years ago, Hippocrates, often regarded as the father of medicine, declared, “All disease begins in the gut.” His insightful words remain relevant today as modern research uncovers the profound connections within our gut, particularly the intricate relationship between the microbiota, gastrointestinal system, and brain—known as the Microbiota-Gut-Brain Axis (MGBA).
The MGBA plays a pivotal role in shaping our psychological health, offering deeper insights into how we think, feel, and experience the world. Housing trillions of microorganisms collectively called the microbiota, and the gut is a hub of complex interactions. These microorganisms constantly communicate with one another and influence key systems within our bodies, including the gastrointestinal, immune, nervous, endocrine, and brain!
NP 120 Part I is the first course in the two-part NP 120 series, which introduces the first evidence-based conceptual model linking the microbiota-gut-brain axis to the diet-mental health relationship (MGBA-DMHR). This MGBA-DMHR is just one mechanism within the emerging field of Nutritional Psychology.
While the microbiota in our gut influence numerous systems in our body and mind, who—or what—is influencing them? The answer lies in the foods we eat. Our diet provides specific instructions to our microbiota, guiding their actions and responses. This highlights the crucial connection between diet, the MGBA, and the DMHR.
NP 120 Part I takes learners through a journey of key components of the MGBA to begin understanding how its systems communicate and influence one another, preparing them to advance their learning of the MGBA’s interconnection with the DMHR presented in NP 120 Part II. Topics include:
NP 120 Part I explains MGBA-DMHR concepts in a way that makes this complex information accessible to anyone interested in this study area and is a prerequisite to NP 120 Part II.

Additionally, to receive the Introductory Certificate in Nutritional Psychology, one must have successfully completed NP 110, NP 120 (Parts I & II), and NP 150.
This course presents evidence, knowledge, and conceptual learning (psychonutritional education) in how MGBA (and diet) influence all aspects of the diet-mental health relationship within nutritional psychology. This course is not designed to provide diagnosis, nutritional, or therapeutic intervention outside of one’s existing professional scope of practice. This course does not provide the following:
This course does provide the following:
A: Yes, this course is taught fully online through the CNP website and can be completed at your own pace.
A: Yes, NP 120 has open enrollment, and you can begin any time.
A: NP 120 Part I is estimated to take 18.25 hours to complete, depending on your learning style and previous experience in nutrition and psychology and whether you've taken NP 110. If this information is new to you, or you are a deep learner, it may take more time to complete.

In this learning journey, we pose questions, present evidence, and impart knowledge. We do this with a vision that alludes to the infinite potential explanations for how our microbiota-gut-brain axis (MGBA) and diet-mental health relationship (DMHR) interconnect. This two-part course introduces the first evidence-based conceptual model linking the MGBA to the DMHR.
M1 focuses on the fascinating journey of discovery and development surrounding the gut-brain axis and microbiota. We will focus on unraveling the intricate communication systems within the Microbiota-Gut-Brain Axis (MGBA), tracing its historical evolution, and examining the research approaches that have played a pivotal role in uncovering its existence and significance.
M2 takes an in-depth look at the gut microbiota. We will explore its composition, diversity, and the factors influencing its development and stability. Through this module, we will gain insights into the crucial role of gut microbiota in maintaining a healthy gut environment and its impact on overall health.
M3 focuses on the gut barrier and gastrointestinal homeostasis. We will examine the structure and function of the gut barrier, exploring how it acts as a defense mechanism against harmful pathogens while allowing the absorption of essential nutrients. Additionally, we will discuss the concept of gut permeability, gut dysbiosis, and eubiosis, along with investigating the role of the gut barrier in MGBA.
M4 delves into the mechanics of microbiota-gut-brain axis (MGBA) communication pathways, facilitating bidirectional signaling between the gut and the brain. We shed light on the bottom-up (gut-to-brain) and top-down (brain-to-gut) communication processes, along with the associated systems and pathways involved in this bidirectional communication mechanism. These pathways include the neural route, such as the autonomic nervous system, vagus nerve, and enteric nervous system; the neuroendocrine route involving hormones and signaling molecules (such as microbial metabolites, neurotransmitters, and neuropeptides), as well as the immune route involving interaction between the gut microbiota or its metabolites with the immune cells.
