In this article, I will analyze diabetes caused by molecular mimicry of A1 beta-casein in milk commonly known as A1 milk.

Beta-casein is about 30% of the protein in cow’s milk. Beta-casein is present as one or two genetic variants; A1 or A2. Most cow’s milk contains a combination of A1 and A2 beta-casein. However, milk that contains only the A2 type without A1 beta-casein alpha is available in some countries.

The second variant, A2 beta-casein, is not associated with diabetes type 1.

The established relationship of this link between A1 beta-casein and type 1 diabetes, and heart disease is 0.982 and 0.76.

This is a very significant level if compared with other epidemiological reasons for these conditions, such as smoking and mortality from lung cancer r = 0.73 or the likelihood of people in the 1960s and heart conditions ten years later where r = 0.85.

The difference between A1 and A2 beta-casein is present because of a single amino acid substitution at 67 line of amino acids of 209 that they have in the chain.

A1 beta-casein in cow milk is different from all other mammals, which exclusively have A2 type including that A2 cattle from Europe of India, and Africa, as Buffalo, is the same with other mammals and the same as human milk. Almost all cattle of the A1 type are related to cows of European origin for the subspecies of the original species of this mutation Bos Taurus.

It is a result of a genetic mutation in cows in Europe that happened about 8,000 years ago. Today, A1 milk cows are bred in Europe and America, and A2 species are bred in New Zeeland. Holstein species have A1 and A2 beta-casein in almost equal amounts. The Jersey species typically has a little more than A2 but is also considered a mixed species. The same Jersey cows carry a “B” beta-casein that has proven to give more BCM7. Signs of poor histidine attachment, A1 beta-casein breaks down into peptides of 7 amino acids called beta casomorphin 7 (BCM7) when consumed. BCM7 is problematic because opiate is at the same level as narcotics like morphine and has similar effects. It is also an oxidant that is known to be detrimental to low-density lipoproteins (LDL). Because the links between 7 amino acids make it extremely strong, it is resistant to further degradation. When BCM7 enters the bloodstream, various problems arise.

However, the BCM 7 is too large to be absorbed by a healthy coat in the intestine, which means that the health problem associated with A1 beta-casein is more likely to be affected by people with damaged digestive health or from diseases such as celiac disease or gastrointestinal disease.

If you have a leaky gut, then you can give yourself and your fetus if you are pregnant type 1 diabetes as an autoimmune disease. if you consume milk and dairy products, that is. Persons having any of the prevailing conditions are more suitable for abscess BCM7. In babies that naturally have increased intestinal permeability in order to improve the absorption of nutrients, there is a higher risk also.

Once it enters the bloodstream, BCM7 can easily break through the blood-brain barrier and enter the brain, where the connection to the receptors causes the symptoms of autism and schizophrenia.

This claim was initiated by research that was disseminated on rats, where rats showed similar tendencies in behavior and sympathy as autism and schizophrenia after BCM7 injection. The association of these effects was also confirmed by the ability to reverse the state and changes in opioid-antagonistic naloxone behavior. To add to that, it has long been recognized that opiates have an effect on immune function, which is the possible reason why A1 beta-casein and BCM7 are associated with autoimmune diseases. In the case of cardiac diseases, additional studies have uncovered the mechanism by which the A1 beta-casein will develop, BCM7 oxidizes LDL that transports cholesterol from the liver to the tissue. This is important because the oxidized LDL increases the risk of heart disease as a result of increased artery incidence and as a consequence Increased plaque accumulation.

Type 1 diabetes, is classified as an autoimmune disease that occurs due to an immune system assault on cells that produce insulin in the pancreas. And it is not genetic as you might lead to believe by conventional medicine. Genetic predisposition plays a role but to prove the fact that it is just one more maladaptation we can look at identical twins. The concordance of diabetes type 1 in identical twins is only 50 %. Meaning one gets it one does not. If it is genetic and the environment does not play a role that would not happen. It is something we ate or to be precise mothers ate or give the babies that cause them to develop this autoimmune disease.

In Japan diabetes type 1 is 18 times lower than in the U.S., but when the Japanese migrate to America and start to adopt the western diet, they develop the same rate of diabetes as Americans. Some countries have 100 times the less diabetes type 1 rates than others depending mostly on the diet the population eats. Type one diabetes started to rise after World War 2 as same as other diseases, so it is not genetics. It is maladaptation, and we now know what is causing it.

In 1999 scholars in Germany discovered that there is a correlation between type 1 diabetes and the level of antibodies to A1 beta-casein. It is believed that these antibodies are, in fact, based on the amino acid sequence of the problematic opioid BCM7, which is derived from A1 beta-casein. Because the sequence has similarities with the protein structure of the cells that produce insulin in the pancreas, the antibodies attack the pancreas together with the BCM7 peptides. In this study, every single kid had significant levels of A1 beta-casein antibodies in their blood but not of antibodies to other milk proteins (1). The conclusion was:

“Patients with insulin-dependent diabetes mellitus have immunity to cows milk albumin, with antibodies to an albumin peptide that is capable of reacting with a beta-cell-specific surface protein. Such antibodies could participate in the development of islet dysfunction.”

Also, there are opiates that cross the blood-brain barrier. Because BCM7 opiates should not be present at all and represent a form of unnatural mutation in cattle it should not be a great surprise in the relationship between A1 beta-casein and casein in general to association with autism also.

BCM 7 obtained from A1 beta-casein and gluteomorphin derived from gluten are both opiates that can be associated with these symptoms. Because of this, a huge number of children with autism show significant improvements if they avoid gluten and casein. The relationship between autism and opiates is nothing new. In 1979, Jaak Panksepp, a scientist, suggested that connection. In 2000, a team of researchers led by Robert Cade reviewed the existing evidence linking the casein and gluten opiates with autism and schizophrenia. They collected new data from 150 autistic children, 120 schizophrenia adults, 43 normal children, and 76 normal adults. Autistic children and schizophrenia adults showed a constant elevated abnormal value of casomorphin and gluteomorphin opioid peptides obtained from beta-casein and gluten.

Actually, all adults show elevated levels of this morphine opioid substance after consumption of milk or yogurt, even the adult that does not have inflammation in the gut at least for 8 hours after consumption (2).

The theory goes something like this. You have a genetic predisposition for diseases such as autism or schizophrenia. This is the so-called “opioid excess” theory. You have a genetic predisposition and then have some early exposure to environmental stressors that damage your gut and make it leaky or you are just a regular baby that naturally has a leaky gut. Then comes the milk or dairy products with all of the casomorphins leaking into the blood in excess and then into the brain triggering disease to form. These opioids are thought that could play one of the roles in the development of autism and other neurological disorders. The problem with these casomorphins is also that when you examine the blood-brain barrier of autism patients, their blood-brain barrier seems weaker too.

In a normal individual, there are going to be some of the sedative effects but in someone with a leaky gut and a leaky blood-brain barrier it is going to have a much stronger effect, and if that person has a genetic predisposition or sensitivity to it then the real disease can form. By the so-called “opioid excess” theory anyway.

Of the seventy autistic children placed on a gluten-free and casein-free diet, 81% showed significant improvements over a period of 3 months, and more than a third of those who did not recover were still high in opioid peptides, indicating that they did not keep the child’s diet. Although only 40% of adults have improved, it is believed that many of them have not been using the diet for long enough to provide their bodies with the ability to eliminate existing BCM7 molecules in the brain that can last for more than a year.

In 1999, Zhongjie Sun and Robert Cade injected BCM7 opioid derivatives from A1 beta-casein into rats to determine if it enters the brain. They found out that it will enter the various areas of the brain that were previously proven to be associated with autism and schizophrenia. As a consequence, it was reasoned that the BCM7 could break through a blood-brain barrier, and hit parts of the brain that are susceptible to those affected by autism and schizophrenia. In the same year, they conducted a similar experiment and found that rats injected with BCM7 exhibited several significant symptoms of autism and schizophrenia such as intolerance, reduced pain sensitivity, and lack of response to external stimuli.

In 2003, Sun and Cade continued their research and discovered that gluteomorphin opioids derived from gluten affect only three regions of the brain while BCM7 opioids derived from A1 beta-casein affected 45 regions. This not only proved that BCM7 comes to the brain much more easily but it is a much larger factor in the development of autism and schizophrenia. Are these studies going to lead to more understanding or better treatment of these individuals I do not know. There could be individuals with a genetic predisposition to these diseases that these molecular mimicry proteins only aggravate. I don’t know. Science still doing research but it is a slow process and who will have the interest to finance these studies? It will take some time.

A1 milk vs A2 milk got a big political issue in Australia and New Zeeland at one point. It ended with obligatory labeling of milk and all dairy products. In Australia, you cannot buy a bottle of A1 milk or any other dairy product without a visible label that shows does the milk contain an A1 or A2 form of protein.

Why are these opioids in the milk in the first place? And there are in all of the milk in existence, not just the A1 milk variant. A1 milk is just a more potent variant. For normal human babies as well as calves, they are there to create a craving or to get them addicted like regular drug addicts are, but in this case, the addiction is going to trigger the baby’s curing for opiates and then the baby is going to get all the nutrition from milk that it needs to grow. It is all as it should be but now we have switched species. Just like the protein amino acid profile of human and cow milk is not the same so the profile of these casomorphins is not the same.

In this study (3) the babies fed on cow’s milk with a higher level of bovine casomorphins seem to suffer from psychomotor delay but exactly the reverse was found for human casomorphins. Human casomorphins seams to help the brain of humans. The conclusion of the study was:

“The highest basal irHCM (human casomorphins) was observed in breast-fed infants with normal psychomotor development and muscle tone. In contrast, elevated basal irBCM (cattle casomorphins) was found in formula-fed infants showing a delay in psychomotor development and heightened muscle tone. Among formula-fed infants with normal development, the rate of this parameter directly correlated to basal irBCM. The data indicate that breastfeeding has an advantage over artificial feeding for infants development during the first year of life and support the hypothesis for the deterioration of bovine casomorphin elimination as a risk factor for delay in psychomotor development and other diseases such as autism.”

The structure of casein in human and cow milk is significantly different matching only by 47%, and especially if we have mutated A1 casein in the mix, then we have a situation that can trigger diabetes type 1 in the baby. Bovine casomorphin is much stronger than human one, and it is almost at the level of morphine in its effect (4). Cow casomorphins bind tighter to the serotonin receptors in the brain than human one does. Also, opioid casomorphins were produced by both A1 and A2 milk with no difference in potency (5). Also, there is much more casein in general in cow’s milk, 15 times more to be precise than in human’s milk. Twenty-one peptides and eight from beta-casein were found in cow milk, and only five peptides with only one from beta-casein were found in human milk.

Should you switch to A2 which is ten times more expensive? What about pizza with A1 milk cheese or any other commercial A1 milk product? Most of the chocolates are made with A1 milk powder. The most realistic scenario is that even if we want to switch to A2 there is no A2 milk around if you live outside of New Zeeland. And even in New Zeeland, there is the chipset powder A1 milk made for the food industry in almost everything. From ice cream to chocolate. And even if we could spend additional money and have that A2 ice cream, milk is still correlated including A2 to a wide range of health issues (Milk and dairy- Health risk correlations).
