Nothing to eat but stale bread and water - an enduring image of incarceration, but what part should food play in punishment? In America, the 'Nutraloaf' - a compressed food-stuff with just enough calories to keep you alive - has been used for decades to punish prisoners in solitary confinement, but many say it contravenes even the most basic human rights. Manuela Saragosa speaks to the man who brought a class action against the state of New York to get it banned. Plus, a prison dietician tells us about the difficulty of planning a nutritious daily menu on a budget of just $2.30 per day.

Food can also play a vital role in rehabilitation and help recreate a sense of normality. We hear from the Dutch prison using nutrition to appease violent behaviour, and find out about The Clink Restaurant - a dining experience with a twist. We get a lesson from a former convict on the challenging art of prison cooking. Finally, when all freedom has been taken from you, how the refusal of food can become a powerful political weapon.
