yeah most of that stuff doesn't really tell you much about the food other than for purposes of weight management in an immediate context.
it's other more obscure stuff that gits you. for instance, what about transfats? oh no those are bad now. what to replace with? how about interesterified oils? those must be good for you. food companies think they are good. and hey, it also happens to be a cheap way of making food that won't spoil!
oh, wait, real food spoils.
but i do love all my oils to be bleached. ummm, bleach.
