I find the first two sentences of your post incoherent. If, as you say, processed food equals junk food, being against it doesn't seem pseud-science to me. You probably meant the term "processed foods" is being used imprecisely to mean "junk food" which is true: the large set of processed foods contains both junk food as well as other kinds of food, some of them being processed by their very nature (like cheese - you can't have "unprocessed cheese"). I wish people stopped using the imprecise phrase "processed foods" and concentrate on the overall effect on one's health. Because singling out any particular component will get you false negatives. Olive oil - high in calories. Feta cheese - high in sodium (and yet, it has an overall good effect on one's cardiac health). Red wine - bad because of alcohol. It's only when you look at the whole you can make a meaningful decision. Yes, it's more difficult and people prefer simple decisions. But your health is worth it.
