I seem to recall that Snapple originally had sugar in it, but the taste changed when they switched to HFCS. Same with Coca-Cola. Although with Coke, at certain times of the year, if you really look for it, you can find "Kosher for Passover" Coke that has sugar, rather than HFCS, and it really does taste better.

Of course I forgot the main reason to use the HFCS and partially hydrogenated fats, they are cheap, cheap, cheap.
