The prisoner's nutrition dilemma

Snacking is pervasive at the Massachusetts Correctional Institute at Norfolk, a medium security prison for men just south of Boston. A pint of Ben & Jerry's is a daily ritual for some, and a common treat is the "honey bun sandwich"—a chocolate bar melted between two honey buns, totaling more than 1,500 calories. The inmates snack out of boredom, missing their families, or depression.
