A new study funded by the left-leaning (and generally pro food regulations) Robert Wood Johnson Foundation and published in the American Journal of Agricultural Economics finds that taxing sodas and other sugary beverages won't help reduce obesity because consumers simply switch to other high-calorie foods and drinks that aren't taxed.

After studying the purchasing habits of Americans throughout 2006, researchers concluded that "Consumers can simply substitute an untaxed high-calorie food for a taxed one…"

I'd say "duh" but that would be mean.
