Have you ever had a gut feeling? Or butterflies in your stomach? Fascinating evidence now shows us that our intestines and brains and intricately linked through a number of physical and biochemical pathways and that our gut microbes are critical to these interactions. In this episode of Biomes, I speak with Professor Ted Dinan from University College Cork, one of the pioneers in the field of the gut-brain axis. We talk about the link between stress and infection, the latest knowledge around the vagus nerve and what diet he thinks may be key to gut-brain health. Enjoy!
