I dunno. I have really bad candidiasis and have had it for over 10 years. Its really entrenched. Once I tried the "Fit for Life" diet which has you eat nothing but raw fruit before noon. I ate only apple sauce before noon everyday for two weeks. My symptoms got worse and worse and worse and worse... and they didn't get any better until I stopped eating all that applesauce.
But then, I was pretty constipated, and the apple sauce was not "clearing me out" like it was supposed to... so I dunno. If you ate nothing but fruit and the fruit made you "go" a lot, like its supposed to, then I bet a fruit diet would cleanse the bowel enough to be effective against candida. But I don't want to chance feeding the yeasts what they want. I'll stick with the regular bowel cleansing methods discussed here - and keep my Sugar intake, both fructose and sucrose, to a minimum.
