> ...fat, salt, and sugar ... contains little in the way of useful nutrition
You're making a good point here, but I'd watch out for this weasely use of "nutrition". Fats and sugars are where energy comes from. Food is made of nutrition. (Otherwise we call it fiber... or Olestra.)
What you mean, I think, is that these foods are designed for their macronutrient content, with a poor selection of micronutrients[0], which could lead to a deficiency if it were all you ate. Which is definitely still a big issue with pre-prepared foods, but it's a lot easier to talk about in an intellectually honest way.
