Lots of marketed (healthy! green! organic!) food is overpriced.  Just hitting up Winco, Costco, and walmart, buying normal food (veggies, salads, meats, etc) and making my own meals is faaaaaaaaaar cheaper than eating out.  And I've been living in poverty for years yet find it fairly easy to eat healthily.  Shit, eating unhealthy processed junk food is more expensive!
