Quoting from the paper:
Sucrose, HFCS, invert sugar, honey an many fruits and juices deliver the same sugars in the same ratios to the same tissues within the same time frame to the same metabolic pathways. Thus…it makes essentially no metabolic difference which one is used.
So, again, while HFCS is certainly a source of calories (and many HFCS containing foods are easily overconsumed), there is nothing special about HFCS that makes it uniquely problematic. Fruit juice or a sucrose containing soda would function identically in the body.
