Candida. Candida is detected using stool testing for overgrowth of yeast and yeast antibodies. Eliminating yeast, sugar, and wheat from the diet helps to starve out candida. People suffering from this disorder should eliminate even honey and fruit sugars from their diet at first, and then slowly reintroduce them into the diet later. Twinlab Yeast Fighters include biotin, fiber, acidophilus, and herbs to support a healthy intestinal environment.
