A2 Milk - All about the new trend

If you like to drink milk, you know that today, from raw milk through pasteurized or homogenized milk to low-fat H-milk, there are different types of milk. Every milk consumer swears by the milk that tastes best. Some people pay attention to the fat content when buying milk.

Beyond such divisions, which affect the buying behavior and the amount of milk consumed, another classification is possible: that in A1 and A2 milk. However, this distinction does not relate to the taste, the type of pasteurization or the fat content, but to the claimed health value of the milk. Learn about the milk trend of today, the "natural whole milk", the original milk in the refrigerator.

What makes A1 and A2 milk different?

Proline instead of histidine

In particular, the composition of the casein proteins or the amino acids contained in them is different. Basically, the difference is quite small. It is only about the beta-casein, where there are proven differences to report. This casein is composed of 209 different amino acids. The composition of the amino acids shows the difference between A1 and A2 milk. At amino acid number 67, the A1 milk contains the basic amino acid histidine, but the A2 milk at this point contains proline. That's just a subtle difference. It does, however, affect digestion.
In the case of the A1 milk - but not the A2 milk - the amino acid chain is disrupted during the digestion process. The reason is still unclear. The result is an opiate called beta-casomorphine-7 (BCM7). There may also be other, previously unexplored differences. The opiate BMC7 has an effect on the digestive tract, above all it appeals to the opioid receptors contained there. The digestion process is slowed down. In addition, the opioid influences the immune system and the neurological system.

In newborns and small children developmental disorders were detected after consumption of A1 milk. In addition, there seems to be a link between BCM7 and early childhood respiratory arrest. In adults, A1 milk is associated with the onset of coronary heart disease and type-1 diabetes. More details must be provided by research over the next few decades. Until then, some people think it wise to avoid A1 milk as much as possible.

A2 Milk - How can consumers differentiate between the two milk types?

The standard is A1 milk

Almost every milk produced in this country is classified as A1 milk. The reason is that almost all European or American cattle belong to the same subspecies. Only the British Jersey and Guernsey cows produce both A1 and A2 milk, or preferably A2 milk. In order to benefit from A2 milk, the customer would need to identify a dairy farmer with Jersey or Guernsey cattle and get his milk from there. Also Indian or African dairy cows - for example the cattle of the Maasai - give A2 milk. But we can not approach this milk in Germany. A potentially interesting alternative is goat, sheep, buffalo or yak milk producers. This is usually also A2 milk.

Why did the difference between A1 and A2 milk come about?

Vorreiter ist Neuseeland

By itself, all cows used to produce A2 milk. It was due to a gene mutation that the preferred breeds in Europe had the histidine in the amino acid chain. It did not remain the only mutation in evolutionary history, as anyone can imagine. The fact is: the beta-casein of A1 milk is very sensitive as far as pasteurization is concerned. Because of this, the critical opioid is created even faster. However, milk research has only been informed about this for 10-15 years. As a trend, the conclusion is that A1 milk has disadvantages from a health point of view. However, this could seriously shake up the majority of the dairy industry, which is focused on A1 milk - and with it the profits of the manufacturers.
In New Zealand, a country where the state of research on milk is already ahead of us, farmers have already taken consequences from the latest findings. They switched the dairy industry to dairy cows producing A2 milk. New Zealand can therefore boast within ten years as the largest producer of A2 milk. We recommend that people with bowel problems such as the irritable bowel strive to avoid A1 milk. Even for small children, the A1 milk may not be good. Goat milk or milk substitutes such as rice milk, almond or oat milk seem to be better as an alternative.

What are the health benefits of A2 milk?

A1 milk not unhealthy, just different.

The protein profile of A2 milk is said to be healthier. Even people with lactose intolerance should tolerate this milk better. Whether that's true, however, is another question. The fact is that there are marketing strategists at work here, who give the A2 milk a boom. For example, this is reflected in the 220 percent increase in the stock value of the New Zealand "A2 Milk Company". It is also a fact that the milk of our cows - especially that of the Fleckvieh - partly contains both A1 and A2 casings.
Taste differences can not be identified by the different amino acids. The fact is that a greater health benefits of A2 milk despite all marketing hype for this trend has not yet been scientifically proven. Therefore, the Consumer Center says that there is no reason to demonize the A1 milk as unhealthy unless there is clear scientific evidence.
