Lots of great ideas here!
When I was pinching pennies while working and going to school (no loans!), I used to buy frozen veggies, chicken, and pasta in bulk. It was a nice change from the terribly unhealthy Top Ramen I was eating every other day...but then, those were like 6 cents a pack or something ridiculously cheap at the the time!
I agree, access to healthy food is a social issue. Some articles refer to it as the "health tax." I live pretty far north and have some Canadian friends, and one of them told me that their government subsidizes groceries nationwide so that everyone can afford decent food. Gas and just about everything else is more expensive there, but apparently not the groceries. I'm sure the system isn't perfect, but I wish the US would make healthy food access a priority like that.
