boingk spot on really, energy in vs energy out, simple calculation, we get so wrong!
Sugar in itself is a hot topic in weightloss and general health at the moment, there are a lot of camps saying that we're eating way too much of the stuff in its processed form (not in say its natural form found in bananas etc) and that the avg adult today has in their kitchen something like as much sugar as say our great grandparents saw in their lifetime...
Personally I haven't been tested but would like to be to see if I am yeast intolerant (celiacs disease), if I eat bread, or quite starchy carb products I often literally bloat out, some people get violently ill. I'd say eat whatever you want, in moderation, move your body and you should be ok!
