> that every sugary breakfast cereal and energy drink would seem quite healthy if all you looked at was the nutrition facts label.

That is factually false, since their labels do quite accurately reflect that they consist of nothing more than carbs (and a bit of protein, for some cereals). I'm not sure how one would come to a conclusion that energy drinks are good for you from their nutrition label, unless you're assuming sugars, artificial colorings, taurine and caffeine are all healthy compounds.
