if you have a candida issue, definitely avoid the fruit sugars for awhile. you may even want to avoid beets, carrots and parsnips, as they are veggies high in sugar, and stick to the dark leafy greens (lots of lemon juices takes away the bitterness, making it easier to go down). there is probably a food chart with glycemic index that will help guide which veggies to juice, but my intuition says organic cucumbers and celery will be a good juice base for you.

i also did a live blood cell analysis before and after my last juice fast, with amazing results. i got to see how my sugar issue plays out in the blood. recently in a POE class (pain and orthopediic evaluation) we had a subject in the class being assessed and it was determined that the reason she was not healing from an injury was due to the fact she's type I diabetes...if the blood sugar remains high all the time, then the body becomes very acidic and has trouble healing (check out acid/alkaline food chart on google)...

for controlling sugar cravings, I use Nature's Plus "Ultra Sugar Control"...two times a day at cravings and after 2 weeks the cravings will subside substantially. Best of luck!
