I agree that some stuff already has a high amount of sugar in it naturally, but I think in the grand scheme of things they make up just a small minority of all products. My concern is for more common stuff, like bread. Why does bread have to have high-fructose corn syrup in it again? The answer is that it doesn't.
Does US bread have more than that?

2 to 4 grams of sugar per slice is typical there. That sort of bread is prepared at large regional bakeries.
Decent grocers will also have a fresh bakery, with somewhat more variety to the product, and probably breads with little added sugar.
If you live in a decent size town, there will also be one or more store front bakeries that uses a shorter list of ingredients (I almost said they are more traditional, but I'm sure they are mostly using big mixers and nice ovens and the like).
Some blame comes down to the producer and marketing trends, gluten is a good example. Up until recently, gluten free had no regulation with using that on packaging. http://www.fda.gov/food/guidanceregulation/guidancedocuments...
When discussing this with friends, I use the example of sodas being marketed as caffeine-free, rather than caffeine added. They are all caffeine free to start.
