As big city living began to replace more rural lifestyles in the 1800’s, cows were taken off their natural pasture land and corralled in inner city pens where they were given grain feed. Since the war of 1812 cut off the supply of whiskey from the West Indies, grain distilleries were built which produced a grain byproduct that could cheaply be fed to cows. This produced inferior quality milk which, combined with the filthy crowded conditions in which the cows were forced to live, created dairy products that were deficient in nutrients and laden with disease-causing microbes. Impure water and poor sanitation added to this bleak situation and tuberculosis reached epidemic levels. The infant mortality rate rose dramatically during the next several years, and it was thought that the milk was largely to blame. It seemed that pasteurization, a process by which the milk is heated to at least 161 degrees to kill pathogens, was the answer.
However, for awhile, some doctors fought to make certified raw healthy pasture-fed dairy available. Unfortunately, in spite of a study that showed that children fed raw milk had more resistance to TB and less tooth decay than children fed pasteurized milk (Lancet, 1937), pasteurization of all dairy became mandatory in most states by the 1930’s.
In fact, up until the early 1900′s, even the Mayo Clinic successfully used raw milk as therapy nutrition for disease-inflicted patients.
I'm really thinking we are going to switch to organic or raw milk. I hope I can find it in town. I wonder if wic will cover at least organic milk. I'm finding that almost everything offered on wic is not that great.
