Q: Dear Dr. Mao,
Is there a way to avoid a yeast infection in the first place?
A: To decrease the amount of yeast in the body, it is recommended to avoid certain substances, including antibiotics, corticosteroids, birth control pills, sugar, and most sweet foods. It is most important to restrict sugar in the diet, even fruit sugar. This concept is based on the idea that “sugar feeds yeast.” (However, there is no scientific evidence that dietary sugar increases the growth of candida.)
