interesting one kama. I had to do a sugar-free diet when I had a candida infection. It was really hard. Are you going to avoid stuff like baked beans, bread, tomato ketchup? Must say, I wouldn't do it again by choice!
Also, I ended up with an allergy that was put down to fructose, because I ate so many bananas and products labelled "no added sugar" which were in fact loaded with concentrated fruit juice.
It was very healthy though - and I wasn't overweight!
