The best replacement for table sugar

I think Birkenzucker for the best substitute for refined table sugar.
He's just as cute as this and know the same ratio of volume to sweetness.
That is, you can do it in recipes 1: 1 use and needs no filler like Stevia.
In addition, birch leaves sugar insulin levels to rise much less as normal sugar.
So it's ideal for people who want to stay slim.
