Then Steve Dubner predicts on the Freakonomics blog that we'll all get skinnier as high fructose corn syrup (used to sweeten everything from ketchup to soda pop) becomes less available or more expensive.

All our resources are at stake, and it's not going to be easy to reduce demand for one by finding substitutes - we're going to have to learn to do with less of everything.
