What Is the Best Prevention for Yeast Infections?

In my opinion, the best treatment for yeast infections is plain yogurt with active cultures. I am not sure there is a best prevention for yeast infections. My personal experience in the prevention of yeast infections is to eat yogurt with active cultures daily and to make sure my blood sugars are under control. I am a diabetic, and it is a fact that diabetics are prone to yeast infections due to the sugar in their urine. If you have any other symptoms of diabetes and have recurrent yeast infections, you should see a doctor. There are also some people who say that caffeine is also a factor.
