I am not certain which clark book you have purchased, but more than likely the Diseases book. Worth noting, she is now against eating fish as she has suggested in her most recently updated HIV book republished in 2003. So she has switched from supporting it to suggesting to not eat it. This is one example why I continually tell people if they have read the Diseases book, they must read the new hiv after that, She has changed a few things from her 1995 published research in the diseases book. She has added new techniques and equipment in the hiv book also. DO NOT DO ANY TEETH WORK SHE RECOMMENDS IN THE DISEASES BOOK WITHOUT READING THE CHANGES IN THE HIV NEW BOOK. That's of course if you are following clark as opposed to say Dr. Huggins's protocol.
