Study indicates that diet in prison influences violence

According to a recent Guardian article, a new trial is to be instituted to try and ascertain a link between better diet in prisons and a decline in both violence and antisocial behaviour .
The inventors of the trial are intending to make sure prisoners have vitamin supplements, as well as minerals and fatty acids . The researchers will measure how this influences the breaking of prison rules.
The research will be lead by Professor John Stein of Oxford University. He will also run research in schools, to assess how nutrition influences concentration. Stein reportedly commented:
“The difference here is we have a proportion of people who in many cases have committed fairly horrendous offences against other people. The question is would they have committed them if they had been better nourished in the community.”
