Hi Robin, If your immune system is sensitized to milk proteins you may be mounting an immune reaction without being aware of it. There are several apparent health benefits that, on closer inspection, may be detrimental. For instance, the calcium in milk is highly bio-available. On the other hand, the calcium overwhelms the active transport capacity that moves minerals from the lumen to the bloodstream. The net result is a shortage of other minerals. Dairy is often recommended to women as a preventive measure for bone density issues but iron storage often suffers as a result of such recommendations. I'd like to suggest that you try strictly avoiding dairy for several weeks. If you then find yourself reacting to the dairy, you will know that it has long posed a health problem to you that had been masked by what Hans Selye called "adaptation" . It might also be useful and interesting to check your status of other minerals, especially iron stores and zinc. Best Wishes, Ron > > -- PK
