The Science of Your Gut Sense & the Gut-Brain Axis | Dr. Diego Bohórquez
· Summarized
Key takeaways
- The gut communicates with the brain through specialized sensory cells known as neuropods, which influence our cravings and feelings.
- Gastric bypass surgery can dramatically change food cravings and preferences, illustrating the gut's powerful role in shaping our dietary habits.
- The language of gut sensation can evolve, allowing for better understanding and awareness of our bodies if we pay attention to its signals.
- Cultural perspectives on food can enrich our understanding of nutrition and health, showing that local traditions and wisdom play a critical role.
- Self-awareness, through practices like meditation, can enhance our ability to listen to our body's signals, leading to better health decisions.
Summary
Introduction to the Gut-Brain Axis
Dr. Andrew Huberman introduces Dr. Diego Bohórquez, a pioneer in understanding the gut-brain axis, focusing on how the gut senses and communicates with the brain. This communication is essential for shaping emotions, preferences, and behaviors in response to what we eat.
The Mechanisms of Gut Sensing
Dr. Bohórquez explains how the gut contains specialized cells that sense various food components like temperature, pH, and nutrients. These sensory cells, called neuropods, communicate with the brain, influencing our feelings and cravings beyond conscious awareness.
Exploring Gastric Bypass and Cravings
The conversation turns to gastric bypass surgery and its dramatic effects on cravings. Dr. Bohórquez shares a story of a woman whose relationship with food changed completely after the procedure, highlighting how our gut can influence our preferences.
The Role of Language and Communication in Gut Sensation
Dr. Bohórquez discusses how the evolution of language reflects our understanding of our bodily functions. He advocates for developing a better vocabulary to discuss the gut’s communication with the brain, which can lead to improved understanding of health.
Cultural Perspectives on Food and Justice
A deep dive into the cultural implications of food, Dr. Bohórquez reflects on his upbringing in Ecuador and how traditional food practices enable better health. He emphasizes how local wisdom about plants can inform better dietary choices.
Psycho-emotional Connections with Food
The discussion covers the psychological dimensions of eating and how our feelings about food can influence our choices. The interconnection between visceral experiences and emotional responses is explored in-depth.
Meditation and Body Awareness
Towards the end, Dr. Bohórquez emphasizes the importance of self-awareness and listening to bodily signals, suggesting that meditation can enhance our understanding of those signals and improve overall well-being.

Show notes
In this episode, my guest is Dr. Diego Bohórquez, PhD, professor of medicine and neurobiology at Duke University and a pioneering researcher into how we use our ‘gut sense.’ He describes how your gut communicates to your brain and the rest of your body through hormones and neural connections to shape your thoughts, emotions, and behaviors. He explains how your gut senses a range of features such as temperature, pH, the macro- and micronutrients in our foods, and much more and signals that information to the brain to affect our food preferences, aversions, and cravings.
Dr. Bohórquez describes his early life in the Amazon jungle and how exposure to traditional agriculture inspired his unique expertise combining nutrition, gastrointestinal physiology, and neuroscience. We discuss how the gut and brain integrate sensory cues, leading to our intuitive “gut sense” about food, people, and situations. This episode provides a scientific perspective into your gut sense to help you make better food choices and, indeed, to support better decision-making in all of life.
