Hi Mary, I know of one book that has been recommended to me several times for the role of nutrition in the prevention of cancer: http://www.vitaminb17.org/ I have not read it, but I did read his book on the monetary fraud of The Federal Reserve (The Creature From Jekyll Island) and it was one of the best pieces of investigative journalism I have ever read. I finally understand how money works :-) I recommend the author. Actually, I just read up the reviews on Amazon, and one of them states that his research is a bit out-dated (which is not surprising given the speed of research), so please bear that in mind. http://www.amazon.com/exec/obidos/tg/detail/-/0912986093/qid=1043357936/sr=8-1/ref=sr_8_1/103-9562792-2315027?v=glance&s=books&n=507846 Although, a bit more research reveals he released another book in 97 to update his research on laetrile: http://www.amazon.com/exec/obidos/tg/detail/-/0912986204/qid=1043358176/sr=1-6/ref=sr_1_6/103-9562792-2315027?v=glance&s=books It's out of print, but I found a copy here: http://search.barnesandnoble.com/bookSearch/isbnInquiry.asp?sourceid=00051864036631554342&ISBN=0912986204&bfdate=01-23-2003+16:46:06 Katrina.
