The surprising ways the microbiome affects our brain development, emotions, and sex lives

We humans are never truly alone. This is because our bodies are colonised by vast numbers of microscopic organisms that can be found living everywhere from the surface of our skin to deep within our guts. Collectively, this population of microbes is known as the human microbiome, and they play a key role in maintaining our health and wellbeing. In this episode we catch up with Dr James Kinross, a colorectal surgeon and researcher based and Imperial College London and author of the new book Dark Matter: The new science of the microbiome. He tells us about the fascinating ways that our microbiomes can impact our brain health, regulate our emotions and if we could ever use them to make an effective love potion.
