There isn't perfect anticandida diet. The perfect candida diet could be only water for 6 months. Brown rice is because the whole grain and the micronutrients, but you can use parboiled rice which has lower glycemic index than the brown. I agree about been gluten free but you don't need to be diary free at least you are reacting to casein or lactose. Even if you react to lactose, you can take lactase enzymes and buy lactose free products. Candida don't feed with lactose even been it the milk's sugar. I don't believe in speculations. I am insisting because I don't see you well guided and know what is to be sick with this. You have to think it is a long journey, and you are in the beginning.
