In a large study with over 400 children, Professor Bisgaard found that the greater the diversity of microbes in the gut, the less likely a child is to develop an allergic response. In other words, when the inner ecosystem is teeming with many different kinds of bacteria and yeast that work synergistically together, children (and adults too) are much less likely to suffer from allergies. These species work together, keeping you healthy. Diversity safeguards against any one organism like Candida from taking over.
