Candida overgrowth is seen most in what is commonly called thrush, or yeast infection. It is usually confined to the skin or mucus membranes, including the nose, mouth, throat, vagina, and penis. These infections are easily treated with natural medicines, probiotics, anti fungals and even good live yogurt. Having healthy gut flora, will keep candida in check. Hv has some very good ideas on how to achieve and keep healthy gut flora, this will help prevent candida overgrowth.
Candida is a normal part of the oral and intestinal flora of human beings, so anyone aiming to completely rid themselves of candida, will be upsetting the natural balance of the body. Its better simply to treat any overgrowth, and build up the good bacteria in the gut, to keep candida in check.
Systemic candidiasis occurs very rarely, and usually in people who are extremely immune suppressed. When candida is systemic, it means that it has reached the blood system, and can spread throughout the body, including internal organs.
People need to realise that systemic candida is very rare, and occurs only in extreme circumstances.
Even if you did have a bout of candida overgrowth, chances are, that with all the good food you eat, the probiotics (fermented drinks), and good supplements you have now, you would not have candida overgrowth. Most people have bouts of candida overgrowth during their lives, but these bouts are short lived, and easy to control.
I think you are also a very wise person Marci, and you also have a good lot of common sense to go along with that wisdom. :)
