From Sunday roast dinners to Friday night takeaways, food has long been a central feature of our lives. We don't just eat for our survival, we eat for pleasure, to celebrate weddings, deaths, birthdays, achievements. Yet we still don't fully understand how the digestive system works, how our bodies choose which compounds to absorb, and how the microbiome in the gut interacts with the brain. In this episode, we meet researchers exploring how these complex systems work and look at whether it's possible to manipulate our feelings of hunger and fullness by using gut hormones.
