Yes you can get control of Candida overgrowth with your diet as long as you are not taking antibiotics on a regular basis. There are anti-Candida diets available for you try. I have posted them before http://curezone.com/forums/fm.asp?i=749181#i
Try and stick to this as best you can. Keep in mind that most of the foods popular in the modern diet are culprits to overgrowth. Stay on the diet for 6 to 8 weeks and see how you feel from there.
What are your diet and health issues you are having that are causing the ongoing problems. Are you on antibiotics, do you have a poor diet high in starchy foods, over eating, birth conrol pills, not drinking enough water, not enough fiber... there are various things that can cause Candida the first place to start is with what you are personaly going through instead of me generalizing.
Yes, you can get your health back on track you just have to give it time and be discliplined with your lifesytle habits.
