What causes insulin resistance?

Concerning Alan Aragon's arguments, they boil down to HFC isn't any worse than sucrose, which is most likely true; however, fructose is still bad, and you should avoid it where possible.

Yes, Lustig agrees with this, noting that within seconds of the sucrose hitting the stomach, the bond between the glucose and fructose is broken. Since most HFCS is around 50% fructose, they are nutritionally very close.

OTOH, because HFCS is cheaper and easier to transport, it finds its way into more foods.
