I can tell you a pretty easy way to tell if you have candida. Eat mainly meat and one three cup salad for a total of 15 carbohydrates for one week. If you don't get a boost of energy by the end of the week or you feel ill and worn out then you probably do. The meat and salad is the basis of the Atkins induction diet and he has that listed as one of the few problems people have with the diet. He has a very restrictive diet for people with candida and it's supposed to eventually cure it but I prefer herbal treatments and a zapper.
If you do the herbals to treat it be prepared to feel lousy and exhausted for a few days as they die off. I think they are why I had an amonia smell about me for a couple of days. I didn't know about Ornithine back then.
