Roughly a decade ago, BALCO did research on mineral readings among athletes. They found short supply of magnesium and zinc. To solve those deficiencies, they applied the standard ca/mg/zn supplements and found no improvement. Subsequent research indicated ca competes with both mg and zn for uptake. Problem was resolved with their ZMA supplement - zinc, magnesium and b6, to be taken at bed time, calcium supplements by themselves 12 hours separate from ZMA. -----Original Message----- From: Paleolithic Eating Support List [mailto:[log in to unmask]] On Behalf Of Ron Hoggan Sent: Wednesday, January 06, 2010 11:51 AM To: [log in to unmask] Subject: Re: Raw milk 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
