Milk intolerance irrespective of source (organic, conventional) is
quite common. The question arises why adult humans should selectively
consume the baby food of another species: its a fairly recent phenomena
in our human evolution. Some are intolerant to milk sugars, others to
milk proteins. Most people can tolerate milk fat however, i.e. butter,
ghee - i rarely see a problem with this in my practice. At the least
milk should never be mixed with other foods (because it increases the
permeability of the intestines), and in best case scenario be drunk
warm and fresh (unpasteurized). So, unless you have a cow in your
backyard or can be assured of the purity and freshness, I would avoid
milk altogether. Some people, esp. where their genetic background
indicates it (i.e. asians, scandinavians etc.) shouldn't drink it at
all. In Scandinavia milk during early childhood diabetes is linked to
promoting a cross tolerance with bovine insulin, leading to the
immunological destruction of the insulin-secreting beta cells in the
pancreas, and the subsequent development of type 1 diabetes. In my
practice, dairy is among the first foods to go in folks with chronic
health problems, esp. those relating to digestive and immune problems.
