RAW & A2A2 Milk Explained

RAW Grass Fed Milk from a Guernsey or Jersey Cow is Best.

The best Milk products are those that come from raw cultured dairy such as yogurt, kefir, cultured butter and sour cream.  The type of proteins in milk, varies depending on the breed of cow and the type of animal (sheep, goat, cow, etc.).

WHY RAW: The pasteurization of milk entails heating it to 145 degrees F for 30 minutes. This completely changes the structure of the milk protein and changes it into something far less healthy.

A major protein 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.

NOTE: Look for A2 as 65% of Jersey and 80% of Guernsey cows tested in the US are pure A2

A2 and the BCM7 Peptide by   David Williams

Most of the milk consumed by humans throughout history has always come from goats or sheep, and it still does. The United States is one of the rare few countries where the milk consumption is almost entirely from cow’s milk. In his book, The Devil in the Milk, Keith Woodford, PhD, professor of farm management and agribusiness at Lincoln University in New Zealand, presents compelling research on the consumption of modern cow’s milk and the state of chronic disease.

The simplest way to explain Woodford’s research is that milk consists of three parts: cream/fat, whey and milk solids. The solids are composed of many kinds of proteins, which are made up of long chains of amino acids. One of these proteins is known as the beta-casein. Approximately five thousand years ago, a mutation occurred in the amino acids of this protein, causing it to produce a peptide called BCM7. The mutation occurred predominantly in cows from Europe but not those from Asia and Africa. Almost all Holsteins, commonly associated with dairy cows (the famous black and-white cows seen in milk commercials), carry this peptide.

Cows that carry the BCM7 peptide are known as A1 cows.  Those that do not are referred to as A2 cows. In other words, the cows WITH the mutation are A1 cows.  What’s important to know is that BCM7 has pro-inflammatory, opiate-like properties and has been shown to contribute largely to a wide variety of chronic diseases, including autoimmune conditions, heart disease, autism, schizophrenia and various neurological disorders. Injecting BCM7 into animals caused Type 1 diabetes to occur. (Interestingly, the French in their culinary arrogance have always refused to use A1 milk in their cooking because they regard it as inferior. Some say the French have terrible manners, but no one disagrees that they make terrific cheese.)

As ominous as it sounds, there’s no reason for too much of an alarm here. BCM7 is not absorbed to any great extent into the human bloodstream of people with healthy GI tracts. However, as in the case of children with autism or those with poor GI function, BCM7 may indeed have a significant contributory role in worsening the disease process.  Having said that however, personal case reports, including my own personal experience, clearly show that milk produced from a cow that is A2A2 (meaning the mother and the father of the cow were BOTH A2 cows) has shown some interesting, if not shocking results.  For example, without any change in exercise routine or diet (other than drinking A2A2 milk and consuming A2A2 cheese), I have personally begun experiencing my body “leaning” out.  An unexpected bonus, my body is getting leaner by the day…not a typically associated benefit from consuming milk.  Of course, the A2A2 milk I’m consuming also is totally raw, completely organic, un-pasturized, non-homogenized, with no GMO grains fed to the cows, on a strictly grass and non-GMO alfalfa with supplemental hay.

Interestingly enough, BCM7 is not found in goat’s milk or sheep’s milk. Raw or not, goat’s milk has been shown to be much easier to digest than cow’s milk. The protein molecules are also much smaller, allowing for better absorption of the nutrients. If you can get goat’s milk, make the switch.  But for some, the taste is different.  A2A2 cow’s milk tastes no different than the A1A1 cows milk, but has the same benefits as drinking goat’s milk.  On a side note, the typical way to refer to a cow when describing BCM7 polymorphism, is by referring to them as either A1 or A2.  However, this is a genetic distinction and as such, the cow can be homozygous for A2 (mother and father both contributed the A2), i.e., no presence of the BCM7 peptide and thus, referred to us as A2A2.  Or, the cow could have had one parent that had the BCM7 peptide (A1) and one parent that didn’t, thus making it an A1A2 cow.  For more information on beta-casein, visit this fantastic link on beta-casein.

The best products of all are those that come from raw cultured dairy such as yogurt, kefir, cultured butter and sour cream.  Not only do these have all the necessary vitamins, good fats, proteins and enzymes, they’re also filled with beneficial probiotics excellent for your immune system and digestive tract. When you consume dairy of this quality, it really does do the body good.
