Have Milk Allergies... this may be why.... A1 Vs. A2 Cows: What’s the Difference? The type of proteins in milk, and the proportion of various proteins, varies depending on the breed of cow and the type of animal (sheep, goat, cow, etc.). One of the major proteins in cow’s milk is casein, the predominant variety of which is called beta-casein. In older breeds of cows, such as Jersey, Asian and African cows (called A2 cows), the beta-casein contains an amino acid called proline. In newer breeds of cows like Holstein (A1 cows), however, the proline has mutated into an amino acid called histidine. This is important because beta-casein also contains an amino acid called BCM-7, which is a powerful opiate linked to negative health effects. Well, the proline that exists in A2 cows has a strong bond to BCM-7, which helps keep it out of the cows’ milk. The histidine in the newer A1 cows, however, has a weak hold on BCM-7, which allows it to get into the milk, and also into the people who drink the milk. So the theory goes that by drinking milk from A1 cows, which are the predominant cows used for dairy products in the United States, you’re exposed to BCM-7, which has been linked to: Neurological impairment, including autistic and schizophrenic changes Type 1 diabetes An impaired immune response Autoimmune disease Heart disease This issue has recently been evaluated by both Food Standards Australia New Zealand (FSANZ) and The European Food Safety Authority (EFSA). FSANZ had this to say: “FSANZ has considered the very limited scientific evidence available on comparative health effects of the two milks and discussed the issue internally and at Board level. FSANZ has noted that further research is in progress and concluded that, while there are some interesting hypotheses being examined, it could not proceed with regulatory action on the basis of the available evidence.” EFSA, meanwhile, which released a review of the issue in February 2009, stated: “Based on this review, EFSA concluded that a cause and effect relationship is not established between the dietary intake of BCM7, related peptides or their possible protein precursors and non-communicable diseases. Consequently, a formal EFSA risk assessment is not recommended. It will be interesting to see whether further research will prompt a different response, but remember that A1 milk is common in the United States, New Zealand, Australia, and Europe, so it will take a major overhauling of the dairy industry … and a revolution of sorts to overtake their corporate interests … to convert herds to produce A2 milk (a move that is actually very simple and requires just a simple test of beta-casein to do). For now, you can get an eye-opening education into the health issues surrounding A1 milk, and why A2 milk appears to be far superior, in Keith Woodford’s book Devil in the Milk: Illness, Health and the Politics of A1 and A2 Milk.
