What They're Saying About High-Fructose Corn Syrup

If you've seen the ads put out by the Corn Refiners group where some actor-playing-douchebag says "Well, you know what they say about high-fructose corn syrup" (apparently aware of all foods that contain it but not what the concern is) but cannot come up with one thing that "they say" and the other person intelligently and succinctly states some crap about it being natural, you might have had two thoughts concomitantly: 1) What is it who's saying about HFCS? and 2) Ooh, it must be natural and ignorant whackos are causing a fuss.

And that's what the Corn Refiners group would like you to think.

But here's just one of the things "they're saying" about why HFCS is some funky shit:
A new study in mice sheds light on at least part of the reason for the insulin resistance that can come from diets high in high-fructose corn syrup, a sweetener found in most sodas and many other processed foods.

Fructose is much more readily metabolized to fat in the liver than glucose, and in the process can lead to nonalcoholic fatty liver disease. NAFLD in turn leads to hepatic insulin resistance and type II diabetes.

Researchers showed that mice fed a high-fructose diet could be protected from insulin resistance if a gene known as transcriptional coactivator PPARg coactivator-1b (PGC-1b) was "knocked down" in the animals' liver and fat tissue. PGC-1b controls the activity of several other genes, including one responsible for building fat in the liver. This suggests an important role for PGC-1b in the pathogenesis of fructose-induced insulin resistance.
But, hey, what's so bad about insulin resistance and nonalcoholic fatty liver disease?

Anyone else find it weird that people who are supposed to sell corn are selling medical advice that benefits their bottom line?
