Question for

 May 2nd: Have you ever tried (or heard of) pure A2 protein cow’s milk?

Answering my own question...

 

Yes and Yes. 

 

But I got to wondering if I have been roped in by hype and slick advertising. So I thought it might be something the hive mind could ponder for a Thursday.

That's the milk from 'old breed' cows like Jerseys and Guernseys isn't it? It's really nice and creamy.

I do not know if either of these statements are true. But they might be. I am not saying you are wrong. 

 

Quote

It's a bit more expensive than normal milk,...

This is true. About $9 a gallon. Whereas the ordinary kind can be had for as little as  $3 a gallon.

...we only buy it if we're making custard or want an especially delicious hot chocolate ::D:

I will take note of that idea.

What is it?

According to the carton ($4.49 per half gallon) it is milk from cows that only produce milk containing a single milk protein (the short designation for it is the A2 protein). 

 

Ordinary, more common milk has two different proteins, designated (you guessed it) A1 and A2.

Sounds like cows that were the result of a mad scientist's work. I'll pass!

I am not sure where the science is on this. I read one article that tracks with what  @Kuroneko said. The article I read said that the cows that produce the two proteins are a recent mutation.  They are all descended from (a Holstein??) a dairy cow that lived around 1500.  Most dairy cattle trace back to that cow, most milk has both proteins, ...most milk is from mutant cows. [!!]

 

Carry on pondering...

Never heard of it and if I have tried it, I was and am unaware.

 

TBH, it sounds like the latest snake oil cure-all.

Most food of any sort that we eat today is from intentionally mutated (which is what "selective breeding" is) animals and plants. This does not confront me.

I have not had this magical milk. Mostly I drink Lactose-free milk, or no milk at all due to some mild intolerance to dairy. Milk seems to kick it off the hardest. I like to keep milk in the fridge for the making of certain things that milk works better for, and I've found that milk in paper cartons keeps far longer than that in the plastic or glass.

I have never heard of it. I rather like the original cow's milk. Lately I think of "new & improved" as "poorly thought out & screwed up".

Ummm no...  :wacko:  I barely drink milk anymore anyway, so "modified" milk is really not high on my list of things to try.

If I have to google it, then I'm pretty sure that my answer is no.

 

There's already way more kinds of milk and milk substitutes than necessary on the shelves, and I'm not even a big milk drinker.

So, thanks to the aforementioned tour driver, I knew A2 milk originated in New Zealand (where dairy is a massive industry). I had assumed that it came from some kind of purpose-engineered cows, but after a few minutes of Internet Research (tm), it looks like the actual crux of the invention was a genetic test which determines the protein types produced by pre-existing cows.

 

In any case, to the best of my knowledge, that single company has been slowly licensing their invention and marketing machine to bring yet another specialized milk to a grateful(?) world.

 



I won't comment on it's relative merits. My system tolerates regular old milk just fine, so I am not a connoisseur of alternate dairy products.

No, but I went and looked it up.  Sounds like spending extra money for no scientifically proven benefit. One bit of light reading for those of you that like it.

 

https://www.nature.com/articles/1602104

 

I guess the abstract is a good short read:

 

Spoiler

 

This review outlines a hypothesis that A1 one of the common variants of β-casein, a major protein in cows milk could facilitate the immunological processes that lead to type I diabetes (DM-I). It was subsequently suggested that A1 β-casein may also be a risk factor for coronary heart disease (CHD), based on between-country correlations of CHD mortality with estimated national consumption of A1 β-casein in a selected number of developed countries. A company, A2 Corporation was set up in New Zealand in the late 1990s to test cows and market milk in several countries with only the A2 variant of β-casein, which appeared not to have the disadvantages of A1 β-casein.

The second part of this review is a critique of the A1/A2 hypothesis. For both DM-I and CHD, the between-country correlation method is shown to be unreliable and negated by recalculation with more countries and by prospective studies in individuals. The animal experiments with diabetes-prone rodents that supported the hypothesis about diabetes were not confirmed by larger, better standardised multicentre experiments. The single animal experiment supporting an A1 β-casein and CHD link was small, short, in an unsuitable animal model and had other design weaknesses.

The A1/A2 milk hypothesis was ingenious. If the scientific evidence had worked out it would have required huge adjustments in the world's dairy industries. This review concludes, however, that there is no convincing or even probable evidence that the A1 β-casein of cow milk has any adverse effect in humans.

This review has been independent of examination of evidence related to A1 and A2 milk by the Australian and New Zealand food standard and food safety authorities, which have not published the evidence they have examined and the analysis of it. They stated in 2003 that no relationship has been established between A1 or A2 milk and diabetes, CHD or other diseases.

      Welcome to Getting to Know You, December 2018 Edition.
       
      The rules as they currently stand:
       
      1. Every day, or so (unless I am out or ill or something) I will post a question.
      1.5. Should I be unable to post a question for the day a crack team of deputy quisitors, former quisitors, and random forum members are all chomping at the bit to step in and post one... 
      2. In theory there is a 24 hour span to answer that question before the next question is posted.
      2.5. (Rule 2 is the most frequently ignored rule.)
      3. Questions are going to be posted between 8:00 hours and 13:00 hours GMT (UK / Europe Time: some Zero Dark Thirty hour for US time zones)
      4. Everyone is encouraged to suggest future questions to be posted via PM to me... (Or Talespinner, he started it.)
      5. You do not have to answer every question to play...
      6. If a question is TMI or N/A simply wait for the next question.. ..or post that you decline to answer (clues regarding why can be fun...unless TMI).
      7. Weekend questions will usually take the form of two or three day quests, starting on Friday or Saturday. 
       
      December will begin ^ with such a question because the month begins on a Saturday.

      The most important thing is to have fun! In fact, its now mandatory

      You thought you were rid of me... you thought "Thanks Gygax's Leather Dice Bag, July is over and we're through with Crowley's stupid questions!"
       
      YOU WERE ONLY HALF RIGHT!
       
      July IS over, but I HAVE MORE STUPID QUESTIONS!!
       
      Now, as a reminder, the obligatory rulze posting:
