I believe a great diet that works for many with an overgroth of candida is The Body Ecology Diet by Donna Gates. Also it would be benificial to supplement with a good probiotic. I have been reading that many are having great success with a combination of latero-sporus which can be found in either Yeast Avenger or Flora Source, and lactobacillus sporenges which can be found in part of a great synergetic blend known as Flora-Source.
The last thing that would be benificial is a candida killer that won't kill your good microflora. Candex is a blend of enzymes that dissolves candida and not friendly bacteria and the bonus...no die off.
