Candida is a very common bacterial flora (it also exists outside the human body in many places) - you need it in your body, however, sugar causes an IMBALANCE of it; an over-growth.

I think the spit test is meaningless. Any test for the presence of Candida is meaningless. This is why there is so much debate about this in the medical field.

I must say though, the symptoms are VERY REAL. I got my problem in check last year after giving up on tow of my own attempts to fix it and I got help from my Naturopath.

There are lots of Candida "theories" out there. Read lots and lots before you do a program to get it into balance again.
