> mainly high fructose corn syrup It should be pointed out that contrary to what many people assume, "high-fructose" does mean that it has more fructose than sugar. Sugar is 50% fructose, and many widely used HFCS formulations contain less fructose than sugar (e.g. the 42% fructose formulation used in most processed food). Even the formulation used in soft drinks is only 55% fructose, marginally more than sugar. If you replace HFCS with sugar in your diet it is basically a no-op in terms of being healthy and in many cases will increase your fructose intake.

In table sugar each fructose is conected to a,glucose in a single molecule (so 50% and 50%). In high fructose corn syrup they are disconected. This cange a lot of things like how fast they get to the blood and how fast cells can use them. I'm skeptical of a lot of good/bad reported health effects, but it's not obviously a nop.

  Fructose can't be used by cells directly - it does not effect blood sugar levels, because it has to be processed by the liver into glucose first.[1] The potential issues with fructose are related to the matabolic processes which convert it into glucose, which is what your cells actually use. So eating say, straight fructose in fact won't spike your blood sugar since it has a much more convoluted metabolic path to consumption. Something like HFCS is more likely to be a problem because the glucose content is not in the dissacharide form of sucrose and can be directly absorbed.

  It's basically a nop. You've got a ton of sucrase in the gut that breaks it down. There is a small difference in the rate of release as a result but it's not clinically meaningful.
