Is a better diet in custody a recipe for success?

 He based his observation on the energy and spirit they appeared to have on release, compared with their sluggish personas on admission. He put this down to the presence of a regular diet instead of the casual "grazing" in which such young people tended to indulge on the outside.

Dalrymple may have had a point, but my experience of eating with young offenders in custody is that their diet is generally a stodgy one. Only recently, for the first time, did I witness the inclusion of fruit. Otherwise, I have queued up with lads in various places to be landed with pie and chips, backed up by a mountain of cheap white bread covered generously in margarine. I have often wondered whether or not this consumption does, indeed, affect their attitude and behaviour, and whether something different might make them more alert or less aggressive. After all, as they say, you are what you eat.
