In this Huberman Lab Essentials episode, I explain how the different nutrients and foods we eat impact our emotions and overall mood. I discuss how the mind-body connection shapes our food choices and cravings, highlighting the roles of key neurotransmitters like dopamine and serotonin in driving eating behaviors. I explain the biological mechanisms behind cravings for specific foods, such as sugar, and how psychological factors like belief effects can influence our perception of hunger. I also describe how certain nutrients, like omega-3 fatty acids, and a healthy gut microbiome are crucial in mood regulation and immune function. Huberman Lab Essentials are short episodes (approximately 30 minutes) focused on essential science and protocol takeaways from past Huberman Lab episodes. Essentials will be released every Thursday, and our full-length episodes will still be released every Monday. Read the full episode show notes at hubermanlab.com.
