I agree that meat shouldn’t be consumed in the first phase. Most, if not all, candida diets allow meat. I mean those diets in the candida books, and several others well designed such as the Modern Herbalist diet, Michael Biamonte,etc.
Meat is a controversial food but isn’t something that will decide if you can cure the overgrowth or not. I mean it isn’t sugar or carbohydrates, but candida also can feed with it. To stop candida from feeding is almost impossible at least you don’t eat anything. The key is to cut its preferred food.
