I think for most people, the problem is what is in the food. Some call it processed food but I don't really know the defination - buts its the junk added to 'enhance' flavor, durability, ease of manufacture, or bulk it up. Look at the ingrediants of commerical salad dressing for example versus a vinegerrete you make yourself. Same with bread, tomato sauce and dang near anything 'convenient'. Yea I'll buy a Pillspury pie crust once in while but to make it live as rolled up dough its got things in it beyond flour, fat, salt and water. I don't think this is the only issue for healthy eating but a big one.
