Kiwi academic and author Professor Keith Woodford hopes the release of his book “The Devil in the Milk” in the United States will lead to further research and debate on the benefits of A2 milk.

Professor Woodford said yesterday that further research exploring the benefits of A2 milk over the more common A1 is likely to be led by overseas interests where the markets are bigger and there is more pressure from consumers to provide the best and healthiest products.
