Candida albicans is very common and by far, the best known type of yeast.
This microorganism normally lives in human mucosa without causing any illness or symptoms. Our colon normally hosts a small amount of those parasites and contains lactic acid, which, with the help of our immune system, keeps them in a latent state. When Candida proliferates in an alkaline environment it can become aggressive and cause problems.
This page provides information on Candida. There is also a Q&A service which gives you the opportunity to ask any further questions.
