I'm glad you mentioned Dr. Lustig's video detailing his and his team's work.
However, you were wrong/mistaken on one of your points –HFCS is bad for you... it's bad for everyone **except, and Dr. Lustig said this, for Ironman-style athletes.
HFCS is both a sucrose and a fructose molecule, combined, therefore it creates a ton of bad co-enzymes in the liver when being processed. Apparently, athletes on that level have a more-efficient liver, yet most Ironmen would never eat HFCS.
America (and Canada, I believe) are the only places where soda/pop is sold with HFCS in it –the rest of the world seems to have banned it in favor of cane sugar.
Even rats aren't as satiated and end up overeating when fed HFCS versus standard corn syrup.
Not all sugars are the same, but they're generally bad for you in refined form. You can eat as much fruit as you want, but you have to have the accompanying fiber... juicing is just as bad for your liver as ethanol, according to the research by Dr. Lustig, therefore eat the whole food.
