Pitseleh,
Claire is talking about a simple "yeast infection" (look at the link). She's also trying to sell you a book on yeast infections, and I assumed that you were speaking of a Candida albicans infestation of your body; there's a HUGE difference between the two.
If you were talking about fungal Candida albicans and not a simple "yeast" then Claire's diet won't even make a dent in your infestation, especially considering the food percentages that she has listed.
