Take a look at my thread about Candida also... Try the spit test, if you have a Candida problem set about the task of purging Candida with immediate haste. If you dont then... keep searching. The main thing is to completely overhaul your diet and start putting good things inside of you... Organic veg etc...
I also suggest amongst other things.
A colon cleanse
A parasite cleanse
A kidney cleanse
A liver cleanse
Transform your diet.
Do the Candida test.
Its takes time and money, but it does work.
Anti-bodies are being produced because your body is dirty for want of a better expression (playing host to parasites, fungus and goodness knows what else), clean it up and get eating healthy food!
