I object to pointing to 'added sugars' as the bad guys. Your body processes added sugar and natural sugar in the same way. Fruits contain vitamins, but they are also high in sugar. So the amazing changes people report might just as well be obtained by taking vitamin pills and more fibers.

I'm not saying that a better diet doesn't make you feel better, just that 'no added sugar' is just a rule of thumb. 'Natural sugar' is not in any way better (or worse) than 'added sugar'.
