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.

Welcome to Huberman Lab Essentials, where we revisit past episodes for the most potent and actionable science-based tools for mental health, physical health, and performance. My name is Andrew Huberman, and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. This podcast is separate from my teaching and research roles at Stanford.
Today, we're talking all about emotions. Emotions are central to our entire experience of life. Whether or not we're happy or sad or depressed or angry is our life experience. And yet I think with all the importance that we've placed on emotions, very few people actually understand how emotions arise in our brain and body.
And I mentioned brain and body because as you'll see today, emotions really capture the brain body relationship. We cannot say that emotions arise just from what happens in our head. The other thing about emotions is that there's no real agreement as to what's a good emotion or a bad emotion.
Today, we're going to talk about the biology of the chemicals and pathways that give rise to emotions in the context of food and nutrition. The discussion around emotions has a long and rich history going back to Darwin and even long before Darwin. You know, this is a conversation that philosophers and scientists have been having for hundreds, if not thousands of years.
You know, the idea that Darwin put forth and that was really attractive for about the last hundred years was that emotions are universal and that some of the facial expressions around emotion are universal and other people have, you know, capitalized on that idea. And to some extent it's true. I mean, I think that the two most robust examples of that would be when we see something
or we smell something or we taste something that we like, there does tend to be a postural leaning in. We tend to inhale air at that time. We tend to bring in more of whatever chemical substance is there. So we tend to do these mm's and kind of lean in closer to things that are attractive to us. And when we see and experience things that we don't like, Sometimes it's a mild aversion.
We just kind of lean back or look away. Other times it's an intense aversion of disgust and we tend to cringe our face. We tend to avoid inhaling any of the chemicals. This probably has roots in ancient biological mechanisms that are to prevent us from ingesting things that are bad for us, chemical compounds and tastes that might be poisonous.
So much of the foundation of any discussion about emotion has to center around this kind of push pull of attraction to things or aversion from things. Now that's a very basic way of thinking about emotions. But if you think about it, it works for a lot of different circumstances.
And in the brain, everywhere from the deep circuits of the brain to the more kind of what we call higher order revolve centers of the brain, we have this push-pull thing where either in a previous episode, I talked about go, the circuits that allow you to emphasize action and then no-go circuits, the circuits in the basal ganglia that allow you to de-emphasize action and prevent action.
