I know for LC diets, a gram of sugar is a gram of sugar regardless of the form.

What I am interested in though is for the general population is something sweetened with fructose actually better then something sweetened with sugar or corn syrup?

The reason I ask is I have a 1 year old. I wanted to get her a cereal bar for a fast snack. All the ones I've found have sugar as the first ingredient, followed by brown sugar, corn syrup and many more forms of processed sugars. Today I found one that has no processed sugars. It has some fruit juices and fruit pastes like raison. The carbs are about the same as for the ones with sugar topping the list though. So are these really better in the long run, or is it more a marketing sceme only?
