Here's a comprehensive explanation why HFCS poisons your body, if you'd like to know more about it.  The Harvard professor tells you exactly the differences between metabolizing HFCS and glucose, to show HFCS produces a lot more toxins than pure sugar.  Of course you've got to sit through 1.5 hours of lecture, but at least it's a great one, and maybe it convinces you (or someone else) to cut back on sugar alltogether.
