Try and find a health practitioner who uses the Asyra Pro system. This is how i found out about my candida last week. if you look at nutrivital.co.uk there is info and a video clip about it. Failing that a kinesiologist would be able to help. I have had food tests and other stuff with one in the past, it works in a similar way to the Asyra – biofeedback from the body. Having trained in basic kinesiology I believe it works and I have always had good results.
