(26,549 posts)HFCS and sucrose follow exactly the same metabolic pathway.
In both cases, the body is absorbing and metabolizing a 50/50 mixture of glucose and fructose.
The obesity you cite isn't caused by switching from sucrose to HFCS. It's caused by eating too many calories for the level of activity. A typical lunch in Latin America has many fewer calories than a typical lunch in the US, for example.
We have a long, long history of people propping up a single chemical as the obesity demon. Until recently, it was fat. Now it's sugar, and especially HFCS. Just buy their book and exciting new diet plan, and you'll be skinny by removing one single chemical.
There really is no obesity demon chemical. It's calories in versus calories burned. Some chemicals make that equation easier to balance, but the important thing is still the underlying equation.
