You got Candida when your body is out of balance. Since the yeast is controlled by your immune system and can't do no harm. Therefore, it is crucial that you have to improve your immune system by any price.
The most effective way to have a very strong immune system is to lift weight. Just start with a low weight and continue building up until you reach a heavy one; the strength of your immune system will be proportional to the weight you add to your exercise. After that there will be no infection, no cold, no flu, no need of medication but the trade-off is you get pollen allergy because your immune system is very sensitive and strong now.
