Well, I don't know, the tests will always come back negative, it's always worth a shot IMO, the drugs are very cheap to get a hold off. You really gotta go all out for the cleansing stuff, doing enemas and whatnot, candida can come out in chunks even. Alright choices for oil, would you ever consider coconut/mct oil?
To be honest, modern food, you are not missing out on much if you exclude the majority. Simple meals like salads with a little bit of MCT, are gonna be 10x more nutritious than consuming stuff like cereals/breads.
