Do We Really Prefer Bland?

I came across this post on Seth Godin's blog today.  It's interesting to see a marketer's view on how the foods that are presented to us as 'normal' can be made so seem that way, and how anything outside that is made to seem extreme and weird.

"How did we get programmed this way? Is it an inevitable part of the human condition to prefer things that are bland, preprocessed and not so good for us? Or did we market ourself into this corner?"

Is this how we went from eating raw food to cooked food?  I suspect that happened before the marketers got involved, but it's certainly one of those things that makes you go, "hmmmmmmmm".
