Difference Between A1 and A2 Milk

Milk is a part of a healthy diet that most people belonging to different classes have access to.  It is a rich source of calcium and protein. Milk also contains many elements, such as lactose, fat, other vitamins and minerals. It is a well-known fact that milk is a rich source of protein. There are two types of casein: alpha casein and beta casein. The largest group of proteins found in milk is just casein, which accounts for 80% of the total protein. Beta casein also has two forms: A1 and A2.

These different forms of beta-casein protein are the basis of the differentiation of different types of milk commercially available in the market. The difference in A1 and A2 is because of the amino acid associated with the beta form of the protein. The A2 is associated with amino acid proline, while the A1 is associated with histidine.  

The article focuses on the discussion of what is the difference between A1 and A2 milk. We will also describe the different impacts on human metabolism based on the difference between A1 and A2 cow milk. The article briefly explains the difference between A1 and A2 ghee.

What is the Difference Between A1 and A2 Milk?

It is critical to understand the differences between the two types of milk in order to make a healthy decision. In today's modern world, A1 milk is the most generally available and consumed milk. Cows of Western origin, such as Holstein Friesian, Jersey, and others, produce A1 milk in large quantities. A2 milk originates from cows with Indian lineages, such as Gir, Sahiwal, and others, which may give less milk.

Milk A1 and milk A2 are the two types of milk available on the market. A1 milk is produced by A1 cows, while A2 milk is produced by A2 cows. When it comes to the consumption of the majority of milk, A1 milk is consumed in significant quantities not just in India but throughout the world. The consumption of A2 milk is low.

Milk contains calcium and protein, as previously stated. Milk contains a number of different proteins, one of which is casein. As a result, we can claim that milk contains 80% of casein protein. However, the indigenous cow that produces A2 milk produces casein protein as well as a form of the amino acid known as proline.

Despite the fact that both types of milk come from the same source, the cow, their chemical contents differ significantly. In both kinds of milk, the lactose (carbohydrate component) and fatty acids (fat component) ratios are different.

The protein content of the milk, on the other hand, is what distinguishes the two in terms of quality. Because of the way milk is broken down and metabolized in the body, this is critical.

What is BCM 7 and its Impact?

A1 milk is cheaper and easier to find than A2 milk due to the difference in availability. However, there has recently been a disagreement concerning the health effects/benefits of each type of milk.

Because of its health benefits, A2 milk is becoming increasingly popular. The presence of BCM-7 (Beta-casomorphine-7) in A1 milk, which is not present in A2 milk and has been blamed for a number of unintended consequences, is one of the main reasons for this debate. The difference between A1 and A2 protein can be further understood by understanding the metabolism of this protein.

BCM 7 cannot enter our bodies because of the proline in A2 milk. What is BCM 7 (Beta-Casomorphin-7), and what does it do?

BCM 7 is a peptide that is found in opioids. It is a tiny protein that our bodies do not digest. This can cause indigestion, and studies have shown that it can lead to a variety of other issues or diseases, such as diabetes. As a result, we can conclude that the proline amino acid in A2 milk blocks BCM 7 from entering our bodies. However, because A1 cows do not produce proline, BCM 7 enters our bodies and dissolves in the bloodstream.

A2 milk is also easier to digest, according to certain studies. According to a paper published by the US National Library of Medicine National Institutes of Health, large levels of BCM 7 are detected in A1 beta-casein milk. If it is given to children, the risk of developing diabetes will increase. 

This study was conducted in the Scandinavian and Dutch countries. A substantial number of persons are diagnosed with diabetes in this area. This could be due to a variety of factors, including lifestyle, but A1 milk has also been linked to the disease. Heart disease has also been related to this milk to some extent.

According to some Russian studies, the BCM 7 enters the bloodstream of children and slows brain growth. The results of this research were published in the peer-reviewed journal entitled "Peptides."

Because BCM 7 enters the bloodstream and then the brain, another study published in the Indian Journal of Endocrinology and Metabolism in 2012 found a link between diabetes type 1 and A1 milk and cardiac difficulties and mental disorders, autism, allergy avoidance, and schizophrenia. A1 milk is not hazardous to the body, according to previous studies. As a result, claiming that A1 milk has any detrimental consequences is false. This has yet to be shown enough.

Metabolism of BCM 7

When the body tries to break down casein in A1 milk, it releases a molecule called BCM-7, which has morphine-like effects on the central nervous system. Because BCM-7 creates milk addiction, children prefer to drink milk all of the time. Because of the presence of a morphine-like molecule in A1 milk, neuro diseases such as cognitive problems, which disrupt learning ability and worsened signs of autism, are also caused. Because the morphine impact causes constipation, children who drink A1 milk are frequently constipated.

The 67^th position in A1 milk protein is occupied by ‘Histidine,' which is released to generate Histamine (causing allergic reactions). As a result, allergic dermatitis (skin allergies), allergic rhinitis (runny nose), allergic cough, and asthma are common in children. Children who drink A1 milk may experience changes in their lipid and carbohydrate metabolism, increasing their long-term risks of obesity and diabetes.

Lactose intolerance is also common with A1 milk. A1 milk's fat and carbohydrate increase the growth of harmful bacteria in the human intestine, resulting in lowered immunity in youngsters. A2 milk, on the other hand, promotes improved immunity. Consumption of A1 milk has been linked to a deleterious impact on the immune hormonal system and type 1 diabetes and heart disease. The advantages of A2 milk greatly outweigh the disadvantages that A1 milk poses to the human body.

In conclusion of the article, it can be said that we have learnt the difference between A1 and A2 cow milk. We have also learnt about the metabolism of the BCM 7 protein found in milk.
