The diet is just low Sugar which i dont really bash but for a weakened immune system its pretty crap and unworthwhile IMO.
The anti-fungals are useless an all candida is a secondary problem show me someone who has got well with them?
Most including myself have dysbiosis, bacterial infections with co-parasite infections and possible toxicity.
Each to their own though this is my theory and you have yours. I went to several naturopaths who told me i had candida years back and did all the anti-fungals, diet for ages and all the other accompanying treatments and got nowhere.
