Otherwise known as yeast infection, Candidiasis is an infestation of the common yeast Candida albicans which is found in every human being in small amounts but, under certain conditions, grows out of control and migrates from the colon to any other tissue in the body causing many different symptoms, both physical and mental. When candida proliferates, it changes into a fungal form which is able to break through the intestinal wall leaving it porous, and this allows both toxins and minute particles of incompletely-digested foods to leak through from the digestive tract into the blood-stream. Not only does this lead to problems of food sensitivity, but it places a heavy load on the immune system, making it even weaker in its fight against candida and other invaders.
