More info on A1\/A2 milk products<\/p>\n
“For some people, cow\u2019s milk is simply devastating to health. We can wish for milk to be healthy because of its calcium and protein. We can hope that milk is better if it\u2019s raw or organic.<\/p>\n
We cannot get around the fact that one of the proteins in milk \u2013 A1 casein \u2013 is highly inflammatory for some people. In susceptible individuals, A1 casein is cleaved to form a powerful immune-modulating opiate called casomorphin.<\/p>\n
Not all cows produce A1 casein. It comes from Holstein and Friesian cows who are the dominant breeds in western Europe, North America and Australia. Milk cows in Africa, Asia, Iceland and southern Europe make milk with mostly A2 casein. Those countries have a lower incidence of the conditions discussed below.<\/p>\n
Milk that has predominantly or exclusively A2 casein is fine for most people. I find this in my clinic again and again. Goat\u2019s milk is A2. And so is milk from Jersey cows. Dairy products that are mostly fat \u2013 like butter \u2013 are also fine.”<\/p>\n
