    3. While regular table sugar (sucrose) is 50% fructose and 50% glucose, high-fructose corn syrup can contain up to 80% fructose and 20% glucose, almost twice the fructose of common table sugar. Calories alone are not the key problem with high-fructose corn syrup. Rather, metabolism of excess amounts of fructose is the major concern. High dietary intake of fructose is problematic because fructose is metabolized differently from glucose. Glucose can be metabolized and converted to ATP, which is readily “burned” for energy by the cells’ mitochondria. Fructose, on the other hand, is more rapidly metabolized in the liver, flooding metabolic pathways and leading to increased triglyceride synthesis and fat storage in the liver. The high flux of fructose to the liver disturbs glucose metabolism and uptake pathways and leads to metabolic disturbances that underlie the induction of insulin resistance, a hallmark of type 2 diabetes. Scientists have therefore come to realize that all sugars are not created equal.

    It's a report, you can check 76 references it has. That quote is readily correct about fructose metabolism understood so far.

    Without controlled research showing at what dose fructose is dangerous and in which populations, none of that is useful. Clearly it's not the case that any amount is always dangerous to everybody. So absent any context, it's little more than fear mongering.

    Suit yourself. Good luck with your health.

    Crap sugar makes me crave more crap sugar, negating the concept of moderation. Crap sugar bloats and constipates me.

    Fruit doesn't bother me at all. Love my fruit.

    As I said, the studies aren't about "regular in terms of common sense" dosages but they're about high fructose intake or HFCS in this case. It's about the fact that the average young adult out there in the US (and probably in most countries around the world based on acquaintances) are getting 18% (Estimated, I've seen higher studies) of their energy intake from beverages ONLY. And that person is likely to have some more added sugars through food. Hence you see most studies going above 20% HFCS intake on subjects as HFCS is the most common sweetener in beverages.

    The body is not made from glass so a can of soda or a candy bar every day is highly unlikely to affect it negatively unless there is a different underlying disease or proneness to one due to other reasons. But 6 cans of soda? (I've seen this amount regularly on forum or even more). All can agree that such a high intake is completely redundant in a healthy diet (doesn't matter if it is HC or HP or HF or a balanced diet). Whereas most people on this site follow it, a random person out there is more close to or above that US national average already. That's the reason I don't dismiss all of those studies including non-human primates and rodents. Whereas you don't take such an amount, it's a public health issue. I'm sure all of the people here, who think this is fearmongering, would have concerns if an immediate relative had such an unhealthy eating habit. That's the point.

    This is a nice study on fructose vs glucose and it's effects on an isotonic diet on overweight to obese people. http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2673878/
    It also counts the gender difference by end results, quantitative measurements like insuline sensitivity decrease significantly in women compared to men. It also links to other short studies involving HFCS.
