I definitely think (and I tell parents this) that I fall into the "middle" between all whole-food/organic/raw from-scratch and everything-from-a-can-or-frozen-box. We eat a lot of fresh fruit, frozen or fresh veggies and I don't often serve white bread but opt for whole wheat/grain. Each meal has a protein, a veg/fruit and a carb of some sort. Snacks include 2 food groups minimum. We limit deep fried foods, I do most things in the oven.
That said, we do have treats sometimes. I know that a granola bar or Nutri-Grain bar is not necessarily "health" food. But we do eat them sometimes. And we have been known to have cupcakes for birthdays, or cookies once in a while for afternoon snack. Maybe once a week or two we have something for lunch like alphabet noodles from a can or hot dogs with boxed mac'n'cheese. I don't give a lot of juice, maybe once a day if that. I do milk at meals and snacks and water in between.
I think we could do better, but I also know that we could be doing worse.
