Why Do Diet Sodas Taste Like Crap?

Why do diet sodas taste like crap? Ed and Alaina both love Diet Coke but I think it's pretty nasty, it's got to be the regular stuff for me, and preferably from a glass bottle or can. Scientists from the University of Illinois Urbana-Champaign say people like me say we don't like diet sodas because of the chemicals, but the real reason we don't like them is because the high-fructose corn syrup in regular sodas give them a better mouth-feel.

I know they've done a study, but still: I call bullshit! Anyone who's ever had a Coke from outside the US or Passover Coke knows that real sugar is where it's at—you get a superior mouth-feel while drinking, and the aftertaste is clean and sweet. Coke made with high-fructose corn syrup is different but still good, but to me the ones made with sweeteners like aspartame and sucralose initially taste too sweet, then get bitter, and then leave my mouth feeling both dry and sticky. Ugh! No thanks! [via The Knowledge for Thirst]
