Awol and Xchocoholic-
I am just curious whether either of you has ever tried raw milk.
I think of regular supermarket milk as drinking synthetic product rather than a natural one.
Also, if your allergy tests are negative for casein, are you sure you aren't sensitive to lactose? In pasteurized milk the lactase that predigests the lactose is destroyed by the process. Some folks have trouble because of the lactose and not the casein.
I do think that diet has a big part in how we feel, and that each of us has very individual responses to foods. What works for some of us will not work for others. I have been tested for celiac (scoped and biopsy) and was negative. But I notice that when I eat wheat products I have certain reactions. So I may not have a 'real' allergy, but I do have some kind of sensitivity and therefore, it does not matter to me what an allergist says to me, I just keep away from wheat, because I listen to my body when it speaks...or at least I try to.
