You've probably seem that commercial from the HFCS folk where the two mommies discuss corn-syrup and the stupid liberal one, who doesn't give her kids HFCS, has obviously done no research, and so gets stumped by the sensible one, who has educated herself, and knows that "in moderation" it's a safe, natural treat, yap yap yap?
Like anyone in America actually consumes HFCS in moderation these days, dude. (24% of most people's diets, that's what this guy says.)
Anyway, here's a science blog, Neurototopia looking at the question in detail. News is both good and bad.
