What is the difference between A1 and A2 milk?

Milk is a wholesome diet that most people of every class drink. It is a rich source of calcium and protein. Several elements are also found in the milk like lactose, fat, other vitamins and minerals. Do you know that milk contains two types of proteins: whey protein and casein protein.

There are two types of casein protein: alpha-casein and beta-casein. The largest group of proteins found in milk is of casein only, which is 80% of total protein.

If we talk about, beta casein, it is also found in two forms: A1 and A2. You must have heard about A1 and A2 milk. What kind of milk are these, does different types of cow produces A1 and A2 milk, what is the specialty of this milk, what are the disadvantages of taking this milk, what is the difference between A1 and A2 milk, etc. Let's study through this article.

What is the difference between A1 and A2 milk?


Today's time everywhere International milk is available in the market and research is going on all over the world between A1 and A2 milk, what is the difference between these two milk etc.? If we talk about any country whether it is Russia, America, India etc. milk is considered as a very important part of the nutrition for children.

Let us tell you that there are two kinds of milk available in the market i.e. milk A1 and milk A2. A1 milk is given by A1 types of cows and A2 milk by A2 variety of cows. If we talk about the consumption of majority of milk then in large quantity A1 milk is consumed not in India in fact in whole part of the world. Consumption of A2 type of milk is low.

We get A2 type of milk from ancient breed cow or the breed of cow running from a long time or from native cow. To some extent, the cow found in East African places and the milk that is obtained from them is called A2 Milk. At the same time, we get A1 milk from the Foreign Breed Cow or from the mixed race cow.

As studied above that milk contains calcium and protein. Various types of proteins are present in the milk out of which, one is casein. Therefore, we can say that, 80 percent of casein protein is found in milk. But the indigenous cow that gives A2 milk, releases casein protein as well as a certain type of amino acid, which is called prolin.

What is Pasteurised or homogenised milk?

Do you know that the protein in milk is converted into peptides? Later it takes the form of amino acids.

Amino acids are very important for our health, but the amino acids that are found in A2 cows play a crucial role.

A1 cows are most commonly found in India and outside countries also. They are also known as hybrid cows. Let us tell you that A1 cows contain a different type of amino acid known as histidine.

In all of these, Amino acid plays an important role. But how? Let us study.

The prolin found in A2 milk prevents BCM 7 to reach our body. But do you know what is BCM 7 (Beta-Casomorphin-7)?

BCM 7 is an opioid peptide. It is a small protein that does not digest in our body. This can lead to indigestion and many researches have shown that it may lead to various other problems or diseases like diabetes etc. So, we can say that proline amino acid in A2 milk prevents BCM 7 from going into our body. But A1 cows do not make proline, so, BCM 7 goes into our body and later it dissolves in the blood.
It can also be understood that BCM 7 protein is not found in A2 milk cows urine, blood or intestines, but this protein is found in the A1 milk cows, due to this it is difficult to digest.

Now, we will study how much BCM 7 is dangerous for our body and what the research says on it. Some research has also revealed that it is easier to digest A2 milk. According to the report of the US National Library of Medicine National Institutes of Health, in A1 beta-casein milk high amounts of BCM 7 is found. If it is given to the children, then problem of diabetes will increase in them. This research was done in Scandinavian and the Netherland countries. Here, it is found that large amount of people are suffering from diabetes. For this, lifestyle may also be one of the reasons but somewhere A1 milk is also connected with the disease. Even, Heart disease has also been linked to some extent with this milk.

According to some Russian researchers, the BCM 7 passes into the children's blood and also retards the development of the brain. This research was published in the International Journal "Peptides".

According to another report, Indian Journal of Endocrinology and Metabolism 2012, diabetes type 1 has some connection with A1 milk and in addition heart problem, mental disorder, autism, prevention of allergic deficiencies, and schizophrenia because of BCM 7 as it goes to the blood and then to the brain. Some other research also says that, A1 milk does not harm body. Therefore, it would be wrong to say that A1 milk has any side effects. This has not been properly proved yet.

Now let's study about Operation Flood and why it was launched?

In the year 1970, the National Dairy Development Board had introduced Operation Flood in India, in order to deal with the lack of milk due to the increase in population in India. The main objective of this project was to increase the production of milk, promote rural production and provide reasonable value to the consumers. Cross-breeding method was used with the import of foreign hybrid species and European species for this purpose. Due to which shortage of domestic cow’s occurred in India.

So now you may have understood about the difference between A1 and A2 milk, what type of protein is found in the milk and which milk is produced in large quantities in the whole world etc.
