My sister is allergic to corn. Corn is tough to avoid, but it really isnt impossible. Corn syrup is easier to avoid if you shop at places like whole foods, even sweetened processed foods there tend to use real sugar instead.

But if you are buying packaged goods HCFS is very very common even in things you wouldnt consider sweet.

No, it isn't. I've been avoiding it for years by eating a whole foods, natural diet, as unprocessed as possible. :)

I'll have to keep my eye on that now that you guys mentioned it. I've not been paying attention to it. What is so bad about it anyway, compared to sugar? Is it just because it is super refined?

Oooh.. if you have the chance, watch the movie King Corn. I think it comes out on DVD later this month.
