How healthy are "Natural" cereals?

Recently, a study from The Cornucopia Institute has stirred considerable discussion because of their claim that many so-called "natural" breakfast cereals are merely marketing hype, and deceptive. Compared to organic cereals, they often contain residues of toxic pesticides and genetically modified ingredients; and sometimes are even more expensive.

The "Cereal Crimes" report is certainly worth reading, even just for its exposure of the marketing of cereal brands. There is no doubt that many companies are jumping on the "natural" bandwagon to entice consumers. It should be pointed out, however, that Cornucopia enters the discussion with its own biases, "promoting economic justice for family scale farming". Obviously, for them large food corporations are a threat on a number of levels.
