Was at the grocery store last night, and needed to pick up some cereal. I normally eat unsweetened shredded wheat, of some sort. Post was at full price, and there was no store brand. But, looking for the store brand, I saw the Kashi 'Autumn Wheat', which looked pretty comparable. They do healthy stuff, right?
So I spent a couple of minutes looking. Kashi has sweetener (dried juice, I believe), and uses organic whole wheat, instead of whatever Post uses. Should be better, shouldn't it? Well, slightly fewer calories (odd, given the sweetener), and more iron, but no B-vitamins, which Post has quite a few of. And Post had small amounts of zinc and... one other mineral.
So, overall, the Kashi is less good for you. Who'd'a thunk it?
