I question the amount of people that actually have systemic candida. Like me, I am certain that many, after experiencing poor health and the usual doctor diagnosis of depression, turned to the internet for answers and what they found was "Candida". Marketing tools like the spit test convinced us that we had a fungal overgrowth and needed to stock up on probiotics and eliminate carbs. I am not completely discounting candida, but believe that it is highly self-misdiagnosed.
