High Fructose Corn Syrup Confirmed to be more unhealthy than sugar

High fructose corn syrup has finally been confirmed by evidence to cause more weight gain that sugar.

The US government, by propping up sugar costs, encourages food companies (like Coke or Pepsi) to use HFCS instead of sugar.  With this new research emerging there are a few story lines I'll be following:

1. How will policy makers resolve the conflict between the health of their constituents with the corn lobby?
2. How will the corn lobby respond?  I've seen ads on TV touting that HFCS has never been proven to behave differently from sugar.  Now it has.  If those ads are displayed anymore, I can see lawsuits.
3. How long until a major company switches back to sugar?  Pepsi has already experimented with "throwback" versions of its products and Mexican coke is very popular.  So is Dublin Dr Pepper.
