I wouldn't throw stones...
HFCS largely comes in two formulations - HFCS-55 (used in sugary drinks) and HFCS-42 (used in baked goods).
Both start as corn syrup, which is created by taking corn starch (long chains of glucose) and adding two enzymes (amylase and glucoamylase) which gives you "corn syrup", also known as "glucose syrup". It's nearly pure glucose. If you buy corn syrup at the store, this is what you get - glucose syrup.
Because it's not very sweet, companies then convert some of the glucose into fructose using another enzyme (Xylose isomerase). This process costs time and money, so they only do it to get to the final ratios they want. This is done in big batches and then the unconverted and converted syrups are blended - essentially they are adding relatively expensive fructose to relatively cheap glucose and not the other way around.
HFCS-55 is 55% fructose/45% glucose and is used to sweeten drinks. While it has a higher ratio of fructose to glucose than does sucrose (50/50), it is also sweeter than sucrose, so companies can use less. Mexican Coke uses 37.5 grams of sucrose per can, American Coke uses 35 grams of HFCS-55 per can. This works out to 0.5 grams more fructose in the American can, but 2.0 grams less glucose in the can. American Coke has, therefore, less calories (140 vs 150 per can).
HFCS-42 is used in baked goods as a fat substitute. It keeps baked goods "fresh" and moist longer, which allows a reduction in fat (which normally performs that duty). If they simply swapped in more sucrose for the fat, the resulting baked good would be too sweet, so they use HFCS-42 (which has a 42/58 ratio of fructose-to-glucose) which is less sweet. The resulting baked good has more overall sugar calories but less fructose and less fat.
I don't drink sugary drinks, so HFCS-55 is moot for me and I generally try to avoid low-fat baked goods (because they suck). Even someone drinking 2 liters of soda per day would only consume an extra 3 grams of fructose (12 calories) while losing 18 grams of glucose (72 calories) - it's a net reduction of 60 calories per day. Which is probably better for you than the nagtive effects of 3 grams of fructose.
