Just wondering...what is your background in the study of mycology? You seem pretty sure that fungus is not a viable cause of IBD, or many even other common diseases. I don't wish for this to be a debate back and forth, but I want to let Val, and others know that it is not just my opinion.
One of many mycology researchers, Dr. A.V. Constantini, former Head, U.N. World Health Organization, has written many books about fungus causing many diseases in man, some being CD and colitis (IBD). I think his book series is called Fungalbionics. I still stand firm that fungus is often an underlying issue of disease, especially those with Crohn's disease or colitis. Again, I'm not talking about IBS. It was an antifungal diet plan and natural antifungal supplements that got me well again (no symptoms. no meds) after 8 years of colitis misery. If you haven't had a history of CD or colitis, perhaps you are not the one to comment on what has helped others who have had those diseases, and I don't mean any disrespect when I say that.
Pubmed has many references to CD/colitis and fungus/yeast being linked...too many to post here. One recent ...
http://www.ncbi.nlm.nih.gov/pubmed/20149741 and another on colitis
With this I end my part of the discussion. If Val would like Crohn's advice, perhaps she can browse the Crohn's disease forum. Many there speak of antifungal programs and the SCD which has helped them. This IBS forum doesn't appear to be the right place to discuss CD or colitis, and I will honor that. Good luck, Val.
