Why A2?

What is A2 milk?

A1 and A2 beta-caseins are the primary protein in cow's milk (80%). Historically, cows produced milk that contained only the A2 form (which more closely resembles human and goat's milk). Somewhere along the line a mutation occurred creating the A1 protein which is now more prevalent among the higher milk producing cow breeds. Older breeds, particularly Jerseys and Guernseys, naturally produce milk with A2 proteins, while Holsteins (black and white) generally produce both A1 and A2. Holsteins are the highest milk volume producing breed and are therefore typically used in commercial dairy operations.

When A1 protein is digested in the small intestine, it produces a peptide called beta-casomorphin-7 (BCM-7). The intestines absorb BCM-7 and it passes into the blood. Doctors have linked BCM-7 to stomach discomfort and symptoms similar to those experienced by people with lactose intolerance.  Symptoms of stomach discomfort, gas, bloating, and diarrhea after consuming dairy products, are typically attributed to lactose intolerance. However, some researchers believe that it is BCM-7, not lactose, that is more commonly producing these symptoms. One study

Consuming A2 milk proteins (opposed to A1) has also been linked to lower incidents of cardiovascular disease, type 1 diabetes, and less severe symptoms of autism and schizophrenia.

At Saddle Back Ranch all of our cows are purebred Jerseys (A2 protein producers). They don't give as much milk as higher producing breeds, but it is better milk.

Like all topics, do your own research.  We are sure you will be thanking us for sticking to A2.
