I looked over Dr. Wilson's site & disagree with him on at least 2 points. It doesn't have to take years to get rid of parasites. I got rid of mine in less than 3 months.
Also, I think there is no way nutritional balancing will kill them all. If they are there they are going to pretty much stay there. And multiply over time. You might kill some with coconut oil & other foods, or keep them from breeding as much, but a healthily balanced body is generally not toxic to parasites. He gives no data, that I saw, to back up what he is saying.
I was eating ultra healthily and it did not cause me to expel parasites. The standard herbals & zappers, & a Sota Pulser, expelled & killed them. Mho.
