Having read the Woodford book and followed this scientific discussion for some time I can tell you the problem about the A1 casein in milk is NOT confined to NZ, and affects most (but not all) countries, including the US. The exceptions (like Iceland and Kenya) are countries or regions where the cows are naturally almost exclusively A2. I can also confirm that the epidemiology definitely points to the A1 casein being linked to a fair range of diseases. What is more, the biochemists have now established the metabolic process by which this linkage can occur. Plus, there are a lot of anecdotal reports from parents of autistic kids in Australia noting a big improvement in condition when they switch to A2-only milk. In the US you are lucky because A2 milk is now available in seven midwestern states in HyVee supermarkets and if there is enough demand for it I'm sure it will become available more widely.
