Nobody thinks prison food is haute cuisine, but could it be so bad it's unconstitutional? The question comes up more often than you might think, and there's one dish in particular that so offends the palates of America's prisoners that it's repeatedly been the subject of lawsuits: Nutraloaf.

Nutraloaf (sometimes called Nutri-loaf, sometimes just "the loaf") is served in state prisons around the country. It's not part of the regular menu but is prescribed for inmates who have misbehaved in various ways?usually by proving untrustworthy with their utensils. The loaf provides a full day's nutrients, and it's finger food?no fork necessary.
