#1 - you don't live in a 3rd world country, so finding good nutritious food is not an issue
#2 - you are a grown adult, so figuring out what is good nutritious food is not an issue (unless you are a mongoloid / man child)
#3 - you have freedom, so you can decide to eat crap or good nutritious food
Furthermore, I would rather have my freedom than being locked up to eat better - especially since I can figure out how to eat better on my own.
Unless of course this was just a thread on how you feel prisoners should be given clods of dirt to eat and a glass of monkey spunk to drink - since they are prisoners. If that is the case, good luck trying to change how prisoners should be treated; because a country with a high rate of prisoners 'should' have their prisoners totally mistreated, so that when they get out they are driven to jam clods of dirt and monkey spunk down the throat of the pissant who pushed for such treatment of prisoners. Yeah, this will totally reform criminals.
