Distinguished psychologist Kimberley Wilson's recent book is Unprocessed: How the Food We Eat Is Fuelling Our Mental Health Crisis. In it, she explores the tangible links between diet and how the mind works. Wilson was a former Governor of the Tavistock & Portman NHS Mental Health Trust and has a master’s degree in nutrition. She also previously led the therapy service at what was then Europe’s largest women’s prison, so she knows first-hand about the importance of food and its role in mental health. Joining Kimberly in conversation is Christian Jarrett, cognitive neuroscientist and editor of Psyche magazine.  We’d love to hear your feedback and what you think we should talk about next, who we should have on and what our future debates should be.  Send us an email or voice note with your thoughts to podcasts@intelligencesquared.com or Tweet us @intelligence2.  And if you’d like to get ad-free access to all Intelligence Squared podcasts, including exclusive bonus content, early access to new episodes and much more, become a supporter of Intelligence Squared today for just £4.99, or the equivalent in your local currency .  Just visit intelligencesquared.com/membership to find out more.
