I have thoughts about that, but IANAN (nutritionalist). Not all energy is the same, as in fructose (in sucrose, which we sense as sweeter) versus glucose (what composes carbs, and also in sucrose), two simple sugars. Glucose goes more directly into the bloodsteam during digestion. Fructose does not go straight to the bloodstream but is processed by the liver. Although it gets into the bloodstream slower, it gets stored by the liver faster, and we use this as an energey resevoir when we are not getting energy directly thorugh digestion. So maybe we crave this somtimes when we need to rebuild our energy stores. Or at least it seems that way for me. I crave sugar/fruit sometimes, particularly after exercising. I don't generally even eat sweets/desserts, so my body apparently isn't fooled into always wanting sugar. I would guess from my experience sugar plays a specific role and I want it at a certain time and not others.

Incidently, I get a headache when I eat processed sugar, but not fruit. (However, fruit will also give me a headache if I carmelize it, cooking it at a high temperature for a long time.) Anyway that is one reason I avoid sweetened foods and maybe why I don't get sucked into eating sugar all the time. And people think I am trying to be super healthy...
