Nutrition researcher here. The combination of free acids and free sugars seems to have a synergistically terrible effect on metabolism. The man who discovered diabetes tried to warn about this. The bottom line is you don't want processed carbs or processed fats. They aren't in a form that is much available in the environment, even supposed similar items like pure honey or cream don't show the same effects. Eat starches, fruit, and natural fats (animal, fish, nuts).

My understanding is that the long glucose chains in starches are still more readily broken down by the human body than individual glucose-fructose bonds in sugar. I've heard conflicting stories about fructose by itself, too (maybe worse than glucose, maybe not; maybe a positive for satiety but depending on how it's timed etc.)

frozen, thawed and reheated rice and potatoes triples their resistant starch content, drastically increasing their satiety.

Please do a post on this. I think the food industry is causing this fat vs. sugar debate to confuse people.
