I read about a study once where a bunch of researchers decided to test which breakfast cereals would allow laboratory animals to survive and thrive (as in maintain or put on weight). Out of all the cereals tested, Cheerios was the only one.

I'm thinking back now to a tour that we took of the Kelloggs Plant in Battle Creek, Michigan. One of the main features of the tour was following the entire process of producing Kellogg's Corn Flakes from start to finish. They were very proud of the fact that each flake was actually a kernel of real corn--that they first cooked the hail out of in big barrel-shaped pressure cookers, then squashed the hail out of so they'd be flat, and then dried the hail out of so they'd be crunchy, which then left the product so devoid of any nutritional value that they had to spray vitamins on the flakes through a big duct over the conveyer belt that dropped the corn flakes into the cardboard cereal boxes. Yum.
