In the study “High –fructose corn syrup causes characteristics of obesity in rats: Increased body weight, body fat and triglyceride levels,”(1) the authors failed to put into perspective the excessive amount consumed by the rats in their experimental design. Translating the study’s reported rat intakes to human proportions, the calories gained from high fructose corn syrup would be equivalent to about 3000 kcal/day all from that single source. In comparison, adult humans consume about 2,000 calories per day from all dietary sources. Such intake levels for the study animals would be the equivalent of humans drinking a total of 20 cans of 12 ounce sodas per day - a highly unrealistic amount. Moreover, the researchers concluded that the rats gained more weight from high fructose corn syrup than they would have from sugar, yet the researchers had no proper basis for drawing this conclusion since they failed to provide sucrose controls for part of the study’s short-term experiments and no sucrose controls whatsoever were present in any of the long-term experiments.
Gross Errors in Princeton Animal Study on Obesity and High Fructose Corn SyrupYour link comes from a group with a financial interest in discrediting the study, and still doesn't disprove the portion I linked, which states that even
with identical caloric intakes rats gain more when consuming HFCS than when consuming sucrose. And while they didn't control with sucrose for the long term studies they DID in the short-term.
"The first study showed that male rats given water sweetened with high-fructose corn syrup in addition to a standard diet of rat chow gained much more weight than male rats that received water sweetened with table sugar, or sucrose, in conjunction with the standard diet. The concentration of sugar in the sucrose solution was the same as is found in some commercial soft drinks, while the high-fructose corn syrup solution was half as concentrated as most sodas."Taamar wrote:

Trying to discredit facts by suggesting the person is of bad character is such poor logic there's a name for it - Poisoning the Well.
Sorry, but if you drink 20 cans of soda a day, I guarantee you'll gain weight; don't need a study to prove that.
Maybe rats don't metabolize things like humans? Then again I guess all those wonder drugs that worked in rats but didn't work in humans should have been a hint.
Why only "male rats"? They did the study using female rats as well, why do you think they are only crowing about the male rats?

- is incorrect. They didn't control for sucrose in any of the long term (6 months) study (Compared to animals eating only rat chow, rats on a diet rich in high-fructose corn syrup [gained weight]...), and they only controlled for sucrose in
part of the short term (8 weeks) study.

Really? When using the study's own error range, the rats consuming sucrose weighed 477 grams +/-9 and the rats consuming HFCS weighed 502 grams +/-11. The rats eating only chow weighed 462. Is that 5 grams significant? But wait - there's more.
The rats who gained more weight on HFCS did so when they were allowed access 12 hours a day. When they were allowed access 24 hours a day they weighed 470 grams. Hmmm, HFCS rats 470 grams; Sucrose rats 477 grams. I wonder why they didn't use that in the press release? I guess
"Rats That Eat Sucrose Gain More Weight Than Rats That Eat HFCS" doesn't push what they wanted to push.
But wait - there's more.
Female rats studied over 7 months fed HFCS 12 hours a day weighed 323 +/-9 grams; those fed sucrose weighed 333 +/-10 grams. Now we know why they didn't tell us about the female rats.
The press release says calorie intake was the same, the study doesn't show how they determined that the calorie intake was the same - for anyone wondering, that's a
BIG no-no.
I guess I'm just not a fan of studies that test to get expected results, but I'm sure people will believe what they want to believe, regardless.
