There's no way around it. If you continue to eat foods high in sugar, it doesn't matter what else you do. You won't get well. All the antifungals in the world won't help you. You can't kill off a yeast while you're feeding it and expect to get better.
Candida overgrowth is stimulated by feeding the yeast or fungus.
You simply have to starve it. A diet high in carbohydrates, such as starchy vegetables, grains, pasta, bread, fruit and fruit juice and refined sugars is not a healthy diet for someone who has an overgrowth of any yeast of fungus. Concentrate on eating lots of vegetables and protein with small amounts of fruit. People often need to be on this diet for three to six months to get results. Because a suppressed immune system makes it difficult to control a fungal infection, you'll also want to boost yours by eliminating any foods to which your allergic or sensitive.
