Believe it or not, if you’ve been feeling like you just can’t bring yourself to focus, are constantly battling procrastination, or even struggling with low mood, it’s probably because you’re not looking after your gut. In this episode I sit down for a conversation with Sophie Medlin, one of the UK's leading experts on gut health. Sophie is a dietitian, chair of the British Dietetic Association and a lecturer at King's College London. In the conversation we discuss how the connection between gut health and mental health has become an emerging area of research, how to feed your body with the right foods to optimise your cognitive performance and we also discuss weird and wonderful nutrition myths that have been circulating on social media over the past few years. Enjoy!
