In the penultimate episode of the series, Lucy seeks the help of two experts who have both studied the field of prison food and understand the scientific implications of a poor diet. Using data and research including the landmark 2002 Aylesbury Prison study that proved nutrition reduced violent offences by 37%, Lucy uses evidence and expert opinion to back up her findings in prisons over the years. She speaks to Kimberley Wilson, a psychologist, nutritionist, author and lecturer who produced a 4-part podcast series, Crime and Nourishment, that asked why - despite compelling evidence - nutritional interventions haven't been introduced across the prison system. Lucy also speaks to Hazel Flight, the Programme Lead for Nutrition and Health at Edge Hill University. Hazel explains why good nutrition is key in tackling behaviour, violence and mental health in prison.  Learn more about your ad choices. Visit megaphone.fm/adchoices
