A really interesting channel in general. The guy has been in an American maximum security prison since age 14 and he smuggles out videos of the various meals he’s given along with his supplemental commissary purchases. Watching a fair number of them I don’t think I’ve seen a meal which has enough calories let alone nutrition for an adult. Usually they include one or two spoonfuls of each dish. A lot of the meals are like two pieces of bread and an expired bag of crisps.
I remember reading that the same companies that make prison meals make school lunches. And sometimes leftovers are reused in prison lol
