How Foods and Nutrients Control Our Moods

This episode explains the brain-body connections that allow the specific foods we eat to control our moods and motivation. I discuss the vagus nerve and its role in dopamine and serotonin release in the brain. I review Omega-3 fatty acids and the key role of the gut microbiome in supporting (or hindering) our mental and emotional states. Many actionable tools are reviewed and discussed related to fasting, ketogenic and plant-based diets, probiotics, fermented foods, fish oils, artificial sweeteners, specific supplements that promote dopamine and serotonin, and some remarkable behavioral (and belief) effects.

Huberman Lab discusses neuroscience — how our brain and its connections with the organs of our body control our perceptions, our behaviors, and our health. We also discuss existing and emerging tools for measuring and changing how our nervous system works. Andrew Huberman, Ph.D., is a neuroscientist and tenured professor in the department of neurobiology, and by courtesy, psychiatry and behavioral sciences at Stanford School of Medicine. He has made numerous significant contributions to the fields of brain development, brain function and neural plasticity, which is the ability of our nervous system to rewire and learn new behaviors, skills and cognitive functioning.  Huberman is a McKnight Foundation and Pew Foundation Fellow and was awarded the Cogan Award, given to the scientist making the most significant discoveries in the study of vision, in 2017. His lab’s most recent work focuses on the influence of vision and respiration on human performance and brain states such as fear and courage. He also works on neural regeneration and directs a clinical trial to promote visual restoration in diseases that cause blindness. Huberman is also actively involved in developing tools now in use by the elite military in the U.S. and Canada, athletes, and technology industries to optimize performance in high stress environments, enhance neural plasticity, mitigate stress and optimize sleep.   Work from the Huberman Laboratory at Stanford School of Medicine has been published in top journals including Nature, Science and Cell and has been featured in TIME, BBC, Scientific American, Discover and other top media outlets.  In 2021, Dr. Huberman launched the Huberman Lab podcast. The podcast is frequently ranked in the top 5 of all podcasts globally and is often ranked #1 in the categories of Science, Education, and Health & Fitness.
