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.
