DeepSummary
This episode features Dr. Diego Bohórquez, a professor at Duke University and pioneer in gut sensing research. He explains how cells in the gut, called neuropod cells, can sense various components of food like temperature, pH, nutrients, and chemicals. These cells then communicate this information to the brain, impacting our thoughts, emotions, behaviors, and food preferences.
Dr. Bohórquez discusses his childhood in the Amazon jungle and how it inspired his interest in combining nutrition, gastrointestinal physiology, and neuroscience. He describes experiments showing how neuropod cells connect directly to the nervous system and brain areas involved in dopamine release and reward. This gut-brain communication happens subconsciously and shapes our intuitive "gut sense" about foods, people, and situations.
The episode covers topics like the impact of gastric bypass surgery on food aversions and cravings, the role of the vagus nerve in gut intuition, and the wisdom of indigenous agriculture practices. Dr. Bohórquez emphasizes the importance of listening to our bodies and intuition alongside analytical decision-making for overall well-being.
Key Episodes Takeaways

- “The gut is the only organ that passes throughout our body, but it is still exposed to the outside.“ by Diego Borquez
- “If you think about it, it's just separated by some compartments that have all of these valves, the epiglottis, the gastroesophageal junction, the pylorus, the ileocycal junction, the rectum.“ by Diego Borquez
- “So when we were able to put these opsins and bring the light and shut off these cells very rapidly, when we had presented the animal with a choice of sweetener over sugar, then all of a sudden, the animal became blind to the solutions. It couldn't discern between the stevia, so to speak, or the sweetener from the sugar.“ by Diego Borquez
