>> If anything, processed sugars like HFCS which is extracted from corn by a chemical enzyme process, could be the cause.

Fructose, which Lustig (and other scientists) suspect as the prime cause is present in both HFCS and granulated sugar (cane or beet). It’s my understanding that the difference in fructose quantity between HFCS (55% Fructose, 45% glucose) and granulated sugar (50-50) is not a significant factor.

Difference between sugar and HFCS in the US is generally people add sugar themselves. And HFCS is added by the producer. Compare you putting a teaspoon of sugar in your coffee with the 10 teaspoons of HFCS in a can of coke. If you buy your coke at the quik mart it may also be HFCS 70/30 to boot.
