OK, obviously it is quite PC to bash high-fructose corn syrup these days, but let's break down that phenomenon a little. This is an issue on at least four fronts - health, politics, taste, and what I'll call, for lack of a better term, lifestyle identification.
On health I can't comment.
Politically, yes, it is completely ridiculous that we as a nation are plundered to the tune of hundreds of millions of dollars to subsidize corn production solely because we have allowed, for whatever reason, the state of Iowa to claim disproportionate influence in our presidential election process. Then there are also the legions of Pollanites who have read the Omnivore's Dilemma, adopted it as a religious text, and yammer on about the environmental impact of "monocultures," which leads to the lifestyle identification point. Bitching about high-fructose corn syrup is of a way of demonstrating to others one's membership in a superior social caste (roughly coterminous with the
Stuff White People Like crowd), whereupon conversation can proceed to other acceptable topics such as how much better other countries are than the United States, how TV sucks (except for Mad Men and the Wire), and the amazing experiences one had backpacking through Thailand or volunteering for Barack Obama.
On the taste issue, I would be shocked - absolutely flabbergasted - if anyone can taste the difference between the corn-syrup version and the cane-sugar version of any otherwise identical product in a side-by-side taste test, without intense familiarity (like, it's practically part of your daily diet) with each one. When it comes to cola I'm inclined to say that the corn-syrup version actually tastes somewhat *less* sweet than the sugar version, and however much one might wish to find some actual, natural, sugar-cane *flavor* in the latter, it simply ain't there. I practically have a cellar full of Coke, Mexican Coke, Passover Coke, and Pepsi Throwback if anyone wants to test the theory. Really! Frankly, the storage vessel (can vs. plastic vs. glass vs. fountain) is a far bigger factor in the final taste of the beverage than whether it was made with sugar or corn syrup.
