Corn in Dr. Pepper?

Really?

           Every day I drink Dr. Pepper and corn is in it?   I think about the industrial food chain and how  corn made it from a field like George Naylor's to my lunchtime can of Dr. Pepper.  I imagine that certian farms grow corn specifically for factories that turn it into corn syrup, and from there it gets shipped out to factories specializing in specific products.  Since the corn from Dr. Pepper comes from corn syrup, I can only imagine that it made on an industrial farm with chemicals (I mean, Dr. Pepper, basically is like a type of chemical as is!).  I would be interested to know/ research what the unintened outputs are of Dr. Pepper.
