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.
