Ammonia certainly is an issue, and will occur due to many poor digestive processes. Mannan occurs due to various reasons as well, and is produced by both good and bad yeasts. The idea is to not let candida become invasive, this will help keep mannan levels down, and assist in a reduction of circulating antigen levels. The interesting thing I've discovered is that there are an incredible amount of strains of candida which can produce many different antigens (some experts even believe the amount could run into millions) which can become highly sensitized to mannan and glioproteins.
The more candida, the more likely the increased biodiversity and complexity of their strains, the bigger the problem. Is it any wonder people can feel half-dead with CRC?
Best way to stop mannan is to halt its production. Same thing with cancer. Show me how to cure it once it takes hold in the human body and metastisizes, it is like stopping a runaway freight train. It can be done in but the very remotest of cases, and with extreme difficulty.
