I haven't checked out the studies but believe you. I think that too many symptoms are attributed to Candida - all sorts of things.In that article he cites 67 published studies, but no one of those studies provides any evidence that Candida can cause (or is even linked to) the symptoms that naturopaths often ascribe to Candida, such as fatigue, depression, brain fog, etc.
I think testing is key but it is not always accurate or affordable for many. I have had tests done by several different labs over many years and I know that when I do feel fatigue and brain fog and often, but not always, vaginal itch that it has always been confirmed on tests done by Metametrix or Doctor's Data etc.
I have experienced detox symptoms if I take a good dose of anti-fungals although I found Diflucan to be pretty symptom-free.
Are you trying to say that Candida overgrowth problems don't exist?
