A1vsA2milk

Milk is a wholesome diet that both vegetarian and non-vegetarian people consume. There are various nutrients inside milk such as lactose, protein, fat, calcium and other vitamins. There are two types of proteins in milk, whey protein and casein protein. Casein protein is also found in two forms: alpha casein and beta casein.

However, beta-casein is also found in two forms; A1 and A2 type. Research by some scientists has shown that A1 type of milk has been found to be associated with heart diseases of the heart. This evidence was found in an animal research that rabbits were given beta-casein A2 in which the amount of cholesterol and thickness of the articular vein got less than those rabbits who were fed beta-casein A1. From this it was concluded that A2 is good milk. Same experiment was done on humans by a scientist named Venn DJ in 2005, in which he fed 62 people in different groups A1 and A2 milk separately for 4 to 5 weeks. In this, he did not find any facts in which it can be said that due to A1 or A2 milk there was an impact on the amount of cholesterol in the blood.

What is the A1 and A2 dispute?

Beta-casein is a main protein in milk of cow, buffalo and other animals. It has been learned from various scientific researches that due to selective breeding and mutation for more milk production, different variants of beta-casein have been formed.

Today we know about 15 different beta caseins. The most important of which are A1 and A2. Beta-casein A1 is considered as bad or bad protein whereas there is a difference of just 1 amino acid in A2 protein.

It is important to know beta casein is a protein that is formed by the combination of different amino acids, just as adding bricks to a wall. Amino acids can be considered bricks and protein as the wall.

A1 protein contains the amino acid called Histidine at 67th position, whereas A2 protein has Prolene on that position. A1 beta casein gets digested into the stomach and creates a new protein, which is biologically and physiologically active, which is called beta-caazomorphin. This is considered to be the major factor behind the A1 protein milk-related illnesses.

Is it true that the desi cow is A2 type and foreign cow is A1 type?

Genomic studies have shown that “Bos” genes in which native, foreign cows and yak fall initially used to be A2-A2 type, but due to genetic mutation, some animals developed A1 type genes.

Later, when the selective breeding started, the bulls that were selected for more milk production and protein were inadvertently A1 types. Due to artificial insemination this resulted in faster progeny of A1 cows.

Some surveys have also found that A1 and A2 are area-specific without breed specific, in North America and North Europe, the frequency of A1 in HF cows is more than 90%, while the frequency of A2 in German HF is more than 97%.

Frequency of A1 in HF breed in all other countries 40 to 65%. In Jersey breed, the frequency of A2 is up to 80% whereas in Indian indigenous cows the frequency of A2 is more than 98%.

So it is not true that domestic cows should be favored more because the milk of buffalo or goat is also 100% A2 type.

What do Indian scientists say about this subject?

It can be broadly said that almost all Indian scientists are unanimous on this subject. NBAGR, which is established in the country by the ICAR, has been working on this topic in Karnal since 2009. In its first report, it was stated that the frequency of A2 in Indian cows is up to 98 percent and in some breeds this is 100 percent and all buffaloes give A2 milk.

They examined the foreign cows in India, which showed that they too have genes only of A2 milk. In an article published in 2012, it was reported that cross breed cows are mainly in the A2 gene category itself.

Does A1 milk cause heart diseases, blood pressure, diabetes or other ailments?

All these false rumors are spread in the media due to less information. First of all, we have to understand that there is a difference between causal factor and risk factor. A1 is not the cause of any disease, it can only increase the apprehension of disease. Some surveys have seen a slight risk, but some people made it a cause for illness.

This controversy was started by Dr. Eliot Group in 1990, in which a paper was published, in which deaths from diabetes and heart diseases were correlated with the diet of those people. Those surveys saw very close links between heart diseases and A1 beta casein, but at high altitude areas such as North America and North Europe.

If India was not a part of this study then its applications do not arise here. There have always been questions on the authenticity of such a Area Restricted Survey Study. And in this study it was also believed that on every person beta casein had a similar exposure, which is not possible at all.

The biggest problem in such surveys is the way they are interpreted. Industries, media and scientists manipulate them as per their own interest and propagate incorrect knowledge in the market. On the contrary, the glycemic index of rice or wheat is more than milk but no one gives attention to it.

Scientists say that no reliable evidence has been found so far that indicates that drinking A1 milk may cause heart disease or diabetes.

A1 Milk In Indian Context

It is a well-published fact that 99.9% of the milk available in Indian market is A1-A2 types and as for A1 milk also Dr. Tracer and the European Food Safety Authority published in 2009 that A1 milk is safe in every way.
