Milk

This article claims that a certain chemical in milk from certain breeds of cow may cause congestion in some people. Since almost all milk in this country comes from one breed of cow (not the way it was a hundred years ago, of course), shouldn't they be more specific? So for those people who overproduce mucus after drinking milk, generally due to conditions caused by inflammation, a dairy elimination diet is shown to work. That must be one of the reasons dairy is banned on the MS diet.
