Yes, it is very confusing, isn't it? Basically, all this stuff (metals, allergies, parasites, candida, liver issues, leaky gut, ph issues, etc.) are all related and form sort of a ball of crap that has to be dealt with very gingerly. It all comes down to where you pull the first string, so to speak, to begin unravelling it. Different people have different advice on where to start, saying you can't get rid of candida unles you deal with X first. I think good advice is to begin with what you can handle (do the things that will cause you the least distress). Anything that is so taxing it will knock you silly is probably not the best place to begin. Candida diet is probably the best starting point for most people.
