Why is High fructose corn syrup bad?

I always hear so much trash about it, but never why it is bad? So?

HFCS is bad in exactly all the ways Sugar is bad, because it IS sugar, just in different proportions. Let me explain:

Sugar (also known as Succrose) is made of just two chemicals: Fructose and Glucose in a 50/50 ratio.  HFCS 55 is the exact same two chemicals, but the Fructose portion is approximately 55% and the Glucose is 45%.  Hence, the name "High Fructose" corn syrup. It is not however "bad" or harmful in any way that Sugar isn't.
