Second that.
Typically, the cheapest items in my grocery basket happen to be the least processed, highest rated in micronutrients. Fruits, vegetables, frozen or fresh; doesn't matter what's in season, brown rice, whole wheat, black beans, eggs, mushrooms, potatoes, etc. About the only expensive minimally processed foods are foods like quinoa, salmon, organic honey.
Key thing to note here is that all of those things are ingredients (barring fruit) that have to be prepped or cooked. Not surprisingly, the no cook, no prep snack/junk foods tend to be eaten first. They also tend to be higher in macronutrients and lower in micronutrients. In other words, foods that I don't need to eat, even just for the calories, since about the last word I'd use to describe myself is starving.
If money is legitimately a factor, then it would behoove the non-wealthy, non-caviar and fois gras eating common folk to follow a health blog or two and learn how to prep food and cook. People have been doing it for millenia; it isn't hard.
