I googled it and found this link explaining the difference, http://healthyeating.sfgate.com/dif...ctose-8704.html I'm sometimes confused by the difference too. Even nice natural cane sugar (sucrose) breaks down into one part glucose (okay-ish) and one part fuctose (bad).

Lustig damns fructose in particular. Not that it's concentrated but that it's the chemical fructose. That's why HFCS justly gets a bad rap. It's near 55% of the bad stuff while white sugar is 50% the bad stuff. "Processed" sweetener is worse if it's HFCS instead of processed sugar because it has higher fructose.

Just to make it more confusing... Manufactures need less HFCS to make something as sweet as if they used sugar so banning HFCS would just cause them to switch to white sugar and use more of it thus negating the purpose of a ban.
