We discussed HFCS in my nutrition class (I am in Med School, so this makes it count, lol) just recently... basically here is how it is... All the research that is being funded on it is coming from two groups. The Pro-HFCS research is being done by the Corn Lobby and the Anti-HFCS is being done by the Cane Sugar Lobby.
Before the Cane Sugar lobby got heavily involved (a few years ago), there was some unbiased research that was done by a couple universities that showed it to do significant liver damage in rats who were fed a HFCS diet. Since that handful of studies, there hasn't been much good research coming out. All of it has been pretty biased and funded by different organizations for their own reasons (think of the "researcher" from Thank You For Smoking).
With all that being said, the process to make HFCS is absurd and expensive. The only reason it ever took off is because our tax dollars were sunk into it. It is cheaper because it is subsidized. If companies didn't embrace it there would never be a demand for it. It is one of those unnecessary things that have now become common place for seemingly no reason. Just take a look at a can of Corn. The put freaking HFCS in it. Why? Fuck if I know; they just do.
I personally try to stay away from the stuff not only because it is seemingly bad for you but it is also a stupid product to begin with.
I know this may come as a shock to you, but your teacher is full of shit.
HFCS became the norm not because it was subsidized, but because sugar had huge tarriffs put on it in a vain effort to protect US sugarcane growers who could not compete with foreign growers. This made HFCS cheaper to use, and food makers quickly shifted. The switch to HFCS had little to nothing to do with corn or HFCS itself and everything to do with protectionism surrounding sugar.
Secondly, the studies she refers to focused on fructose, and not HFCS vs sugar. In fact, all the studies people claim shows harm from HFCS in fact, does nothing of the sort, they show the danger of fructose. Sugar is 50/50 fructose/glucose. So is HFCS at 55/45. They are the same and the body metabolizes them exactly the same. In fact, no valid study shows any difference in health between people who comsume the same amount of calories of sugar, vs HFCS.
And the rat/liver study is recent, not old.
A study in mice suggests that fructose increases obesity.[30] Large quantities of fructose stimulate the liver to produce triglycerides, promotes glycation of proteins and induces insulin resistance.[31] According to one study, the average American consumes nearly 70 pounds of HFCS a year, marking HFCS as a major contributor to the rising rates of obesity in the last generation. [32]
In a 2007 study, rats were fed a diet high in fat and HFCS and kept them relatively sedentary for 16 weeks in an attempt to emulate the diet and lifestyle of many Americans.[33] The rats were not forced to eat, but were able to eat as much as they wanted; they consumed a large amount of food, suggesting that fructose suppresses the sensation of fullness. Within four weeks, the rats showed early signs of fatty liver disease and type II diabetes. Shapiro et al. fed rats a high-fructose diet for six months and compared them to rats that had been fed a fructose-free diet. Although the rats that had consumed high levels of fructose showed no change in weight, when compared to the rats that had consumed no fructose fat, levels of leptin in the blood indicated the development of leptin resistance. When the rats were switched to a high-fat diet, the leptin-resistant rats gained more weight than those who had not developed the resistance.[34]

You'll note that there is no sugarcane control group. Only HFCS and a fructose free (sugar free) control. It's meaningless to use this to claim HFCS is worse than sugar, because sugar would have had exactly the same effect. Why? Because both contain roughly 50% fructose.
Is fructose bad for you? Yep, in anything but extreme moderation, fructose is far from good for you. Be it from sugar OR HFCS it's just not a good thing to take in excess.
Loading up on sugars has ALWAYS been bad for you. Sugar is a tool for instant energy, not a daily food for sedentary people.
Edit: To head off the bullshit let me reiterate that I have no interest in HFCS or corn growers. In fact, I fully support the dropping of all sugar tariffs and loath trade protectionism. I have recently AND in the past been consistent on opposing protectionism in any form. Why do I "defend" HFCS? I don't. I hate baseless hysteria and the twisted, highly self defeating notion that obesity problems have an external boogyman.
