In the yeast state Candida is a non-invasive, sugar-fermenting organism, while in fungal state it is invasive and can produce rhizoids, very long root-like structures. Rhizoids can penetrate mucosa or intestinal walls, leaving microscopic holes and allowing toxins, undigested food particles and bacteria and yeast to enter the bloodstream. These condition is known as Leaky Gut Syndrome, one more name for the food and environmental intolerances.
