I disagree. Overexposure to such rich (read: crap) foods have definitely dulled my own palette. It wasn't necessarily entitlement culture since it was all junk food I'd bought myself during high school, but I'm definitely regretting it now.
Disagree all you like, but other news sources are reporting that it's a result of a form of autism.
Which makes it a chiken and egg problem because Autism has been linked to... diet. There's a lot of new research now on the links between the gut and the brain.
