I'm glad you unearthed Todd's earlier idea about dairy foods.... it's such a great topic, and it might have been lost forever beneath a mountain of subsequent postings. As for fermented milk products, I'm afraid I have some bad news. See, the trouble with milk can't be blamed solely on the lactose and other carbohydrates that are largely removed by fermentation. Proteins in the milk of other animals (besides humans), left nicely intact despite fermentation, are thought to be foreign enough to the human body to disturb our immune systems. One such protein is an enzyme called xanthine oxidase (go to link below). I know people who eat lots of fermented dairy, seem to digest it very easily, and never have any discomfort, health problems or symtoms of any kind that they can directly associate with their dairy consumtion. However, like most people, many of these dairy eaters have one or two anoying ailments like rhumatoid arthritis (worse than anoying), occasional headaches, frequent sinus infections, allergies etc., and I can't help but wonder if any of this could be related to their diet. What would happen if one of my ailing friends didn't eat any dairy whatsoever for a month? Even for those who generally feel fine (no noticeable ailments), would they wind up feeling even better after quitting dairy foods? Check out some of the discussions in the PALIODIET archives on the subject of dairy or milk. Here's one in wich Loren Cordain discusses several issues. Look at item #7. It's about dairy, and although it doesn't mention fermented dairy, it touches on proteins, mimicry and autoimmune responses and thus applies to fermented as well as non-fermented. http://maelstrom.stjohns.edu/CGI/wa.exe?A2=ind9710&L=paleodiet&P=R706 Also, although I havn't read it myself, Dr. Cordain recommends the following book in another of his postings: Oski FA. Dont drink your milk. Syracuse, N.Y., Mollica Press, Ltd., 1983. By the way, I couldn't locate my source that links dairy to IDDM, so if anybody is curious, I apologize. B. Lischer
