5. The Impact of Diet on Crime
About this Lecture
In this fifth module, we think about the impact diet can have on how criminals behave, focusing in particular on: (i) the role that low levels of vitamins, minerals, essential fatty acids and blood glucose can play in increasing violent behaviour; (ii) Benton’s 1996 research, which found a link between low blood glucose levels and irritability; (iii) Gesch and colleagues’ 2002 research on the positive impact of nutritional supplements on prisoners’ behaviour; (iv) findings that too low and too high levels of omega-3 fatty acids can negatively impact behaviour; (v) strengths and weaknesses of the dietary approach to tackling anti-social behaviour.
This course, by Professor Ciarán O’Keeffe (Buckinghamshire New University), explores crime investigation and prevention. In the first module, we think about evidence collection and how an interview differs from an interrogation. In the second module, we think about the cognitive interview by working through each of its stages, as well as the five additional considerations put forward in the enhanced cognitive interview. In the third module, we think about primary crime prevention, including target hardening, improving street lighting, the use of defensible spaces, the installation of CCTV and the implementation of zero tolerance policies on crime. Next, we think about Kelling and Wilson’s 1982 ‘broken windows theory’ and Zimbardo’s 1969 study using abandoned cars to assess the impact on crime levels. In the fifth module, we think about dietary treatments to reduce crime, including nutritional supplements. In the sixth and final module, we think about the impact that hormones can have on criminal behaviour, as well as some of the hormone treatments that have been implemented for sexual offenders.
