Cold Cereal = Kibble for Humans?

I'm eating cereal the other day and suddenly think, "Wait a minute, isn't this like kibble?" It's a (mostly) grain product full of vitamins and minerals. And we're trained to think of it as a whole meal or the main part of balanced meal.

Some of it's even shaped the same way. There's amorphous nuggets, balls, "treasure chests" which look like squared nuggets with two pinched waists to me (is there a message in there?). There's even Scooby Snacks! OK, now I want to try these snacks; there must be something to them to turn a scaredy dog into a mighty dog.

Here's to being trained to eat processed foods full of nutrients!
