I'm not sure that's necessarily true. You can eat a healthy diet for very cheap. Rice, beans, most in-season fresh vegetables, out-of-season frozen vegetables, flour, peanuts, oatmeal, sweet potatoes, russet potatoes, etc are all quite cheap. Throw in some spices and your protein of choice, and you can eat more cheaply on these foods than on a "not caring about what you eat" diet of lean cuisines, fruit loops, and poptarts.
