What DNA Says About Aryan Invasion Theory -2

[Husky]

Reinstating one half of the stuff I snipped in the above post, because I found some links for support.

Indian cow and buffalo breeds possess a rich A2 allele gene that provides a better and healthier quality of milk than foreign breeds, according to a new study.

A2/"Asian cows" milk being specifically good for you vs "European cows" milk being bad for you was already established quite some years ago. And IIRC A1 milk is supposed to cause or exacerbate the onset of mental problems as well, not just cardiovascular disease. Don't quote me on this: only vaguely know about the matter as it was a cause of concern for my mother - she was trying to discourage us from drinking so much of the local milk (I tended to down many glasses on a good day).

Things I didn't post with the above (edited them out before posting, since I wouldn't bet on my memory over this and, being unable to confirm at that time, didn't want to get called on it):



2. "African and Asian cows" => "A2"

3. Presence of A1 in cows (mainly European) were due to 'recent' mutations



And point one is this line:

1. "IIRC A1 milk is supposed to cause or exacerbate the onset of mental problems as well, not just cardiovascular disease."

Again, I recalled autism and schizofrenia (in that order), but I wouldn't bet money on my recollection.



A simple web search gives some indicators that my memory wasn't off . The following is not an endorsement of anything (the links are certainly not verified).



a) Mentions "African and Asian cows" <-> A2.

And mentions of autism.

Shifting from A1 to A2 milk

Sunday, 23 September 2007, 4:44 pm



Press Release: Professor Keith Woodford



Media release for immediate use





Shifting from A1 to A2 milk - Infant formula a priority - let's get on with it says Woodford



NZFSA is claiming that Professor Keith Woodford presents no strong evidence in his book "Devil in the Milk" linking illness to A1 beta-casein. NZFSA says both milks are equally safe. The Authority remains in denial. Woodford's evidence is drawn from more than 100 scientific papers. It includes the following:



NZ scientists have found that countries with high A1 beta-casein intake are the same countries with high Type 1diabetes (the early onset form). The relationships are so strong that the possibility of getting them by chance is less than one in a thousand.



Japanese and German scientists have independently shown that beta-casomorphin7, which Woodford call's the 'milk devil', is only released from A1 beta casein and not A2. This milk devil is undeniably a strong narcotic. American scientists have shown when it is injected into rats it causes bizarre behaviour.





NZ scientists have shown that almost 50% of mice fed A1 beta-casein get diabetes whereas there is close to zero incidence amongst those fed A2. The only counter evidence is a trial where the industry researchers who supplied the diets never confessed publicly to major diet contamination. (The 'milk devil' protein fragment was accidentally added to the A2 diet. The documentation is in Woodford's book.)



Canadian scientists have shown that rats fed A1 beta casein have much higher diabetes than those fed A2.



Finnish scientists found that genetically susceptible children were five time more likely to get diabetes on a high milk diet (and hence high A1 beta-casein) than those on a lower milk diet.



Italian scientists found that diabetics have much higher antibodies to beta casein than non diabetics. German scientists have shown that in diabetics the high antibodies are specifically to A1 beta casein.



Two groups of NZ scientists have shown that deaths from heart disease are much higher in countries where there is high intake of A1 beta-casein. There is less than a one in one thousand probability of getting these results by chance. Also, the Masai people of Kenya have a huge intake of milk but no heart disease (or Type 1 diabetes) But then their milk is A2. Similarly for the Tibetan Highlanders. And on the Island of Guernsey, where the milk is A2, both diseases are very rare.



Australian scientists found that rabbits fed A1 beta-casein develop arterial plaque in a period of weeks whereas those fed A2 do not.



French scientists found that the milk devil oxidizes LDL (an early indicator of heart risk). And Czech Republic scientists have shown that infants fed formula milk have up to 10 times the antibodies to oxidised LDL compared to those who are breastfed.



American, British and Norwegian scientists have all shown that autistic children typically (but not always) excrete this milk devil in their urine. This means it is getting through from the intestines to the blood. Most normal people seem to excrete it out the backend. But American scientists have shown that once in the blood it passes easily into the brain.



There are several trials in America, and Norway showing how autistic children have reduced autistic symptoms if access to beta-casein is removed. Given that it is an opiate, the children often go through withdrawal symptoms.



There is lots more evidence in Woodford's book



In NZ we already have about 900,000 pure A2 cows - perhaps even more. We can breed the rest of the herd across to A2. The existing A2 cows are more than enough to supply all milk products for NZ and Australia. But of course Australia also has its A2 cows - probably about half a million.



[color="#FF0000"]A1 beta casein is mainly a problem of the developed world. Indigenous Asian and African cows are A2. The A2 version of the gene also predominates in southern Europe. Goats, camels, yaks, and almost all sheep are A2. Human milk is of the A2 type.[/color]

A2 is an opportunity which the industry has turned into a threat by pretending there is no issue.



There are solutions. As well as breeding out the gene we can use the A1 milk for particular products such as butter (no risk) whey powders (no risk), and cheese (probably low risk).



Infant formula is the most urgent priority to shift to A2.



"Let's get on and do it!" says Woodford

Devil in the Milk

Kicking it a bit old school tonight as I've spent the last week or so coming up to speed with the issues around A1 vs. A2 milk - issues that are probably the best part of 4-5 years old.



For the uninitiated, A1 & A2 refer to a type of protein contained within milk, specifically, the beta casein protein. It would seem all mammalian milk contains these beta caseins. Human milk, goats milk, sheeps milk, and some cows milk, is all A2. However, due to a mutation, many cows also produce A1 casein. It is this A1 casein that is the likely culprit for peoples reactions to milk and it is the compound that New Zealand agricultural scientist Keith Woodford gained notoriety for when he published his book "Devil in the Milk."



Book overview:



This groundbreaking work is the first internationally published book to examine the link between a protein in the milk we drink and a range of serious illnesses, including heart disease, Type 1 diabetes, autism, and schizophrenia. These health problems are linked to a tiny protein fragment that is formed when we digest A1 beta-casein, a milk protein produced by many cows in the United States and northern European countries. Milk that contains A1 beta-casein is commonly known as A1 milk; milk that does not is called A2. All milk was once A2, until a genetic mutation occurred some thousands of years ago in some European cattle. A2 milk remains high in herds in much of Asia, Africa, and parts of Southern Europe. A1 milk is common in the United States, New Zealand,



Australia, and Europe. In Devil in the Milk, Keith Woodford brings together the evidence published in more than 100 scientific papers. He examines the population studies that look at the link between consumption of A1 milk and the incidence of heart disease and Type 1 diabetes; he explains the science that underpins the A1/A2 hypothesis; and he examines the research undertaken with animals and humans. The evidence is compelling: We should be switching to A2 milk. A2 milk from selected cows is now marketed in parts of the U.S., and it is possible to convert a herd of cows producing A1 milk to cows producing A2 milk. This is an amazing story, one that is not just about the health issues surrounding A1 milk, but also about how scientific evidence can be molded and withheld by vested interests, and how consumer choices are influenced by the interests of corporate business.



From what I have read, I would rate the books author, Keith Woodford, in the same category as outspoken anti-gluten campaigner, Dr Rodney Ford (both are good Christchurch lads) in terms of both being a bit ahead of the game and being relatively lone voices in the warnings they have sounded (Ford on gluten & Woodford on A1 beta casein). I am hopeful that both will be able to sit back at some point in the future, thumb their noses at the establishment, and have a smugness that goes with knowing that they were right all along.



Keith runs his own blog site (keithwoodford.wordpress.com) where I have been catching up on his updates on this issue. Prior to doing this, I was under the impression that nothing much had happened in recent years since the initial publishing of his book... WRONG! Thanks for playing...



There is a good interview here from Dec 2009 that gives an excellent overview of the topic and where Keith slots into this picture.



There’s a devil in the milk, says agricultural scientist Keith Woodford, and it has little to do with production methods. Woodford’s startling thesis, backed up by a pile of research, is that a mutation many years ago created an aberrant protein in some European cows, called A1 cows to set them aside from all other cows, which are called A2. As a result, the milk from these cows has been linked to a host of maladies, including Type 1 diabetes, autism and heart disease. Still virtually unknown in this country, the A1-A2 question is prominent enough in New Zealand, where Woodford lives and works, to have spurred public controversy and the creation of a successful company that markets only A2 milk, the a2 Corporation. For growing numbers of Americans who have noticed that milk seems to attack their systems even though they are lactosetolerant, Woodford’s work, collected in his book, Devil in the Milk, offers vital illumination.



Clearly, Keith hasn't made much headway in terms of the political and economic forces that would rather this issue go away. For a good summary of these issues and the politics that has driven this debate away from the public eye, read Keith's recently published update (May 2010) to his "Devil in the Milk" book here.



Since ‘Devil in the Milk’ was first published in September 2007, the story has moved on considerably. The purpose of this update is to summarise the main events, recognising that it will continue to be an ongoing story, and only time will allow some events to be seen in their appropriate context. Essentially, there are three parts to the ongoing story. The first is about the politics of milk and health, how information is communicated, and market responses. The second is about what is happening ‘behind the scenes’ to Australian and New Zealand dairy herds. The third is about the new science.



All are important to an overall understanding.

c) The following indicates that Europe's A1-milk producing cows developed afterwards. (Mutation. Etc.)



Age of A1 milk cows:

http://ideamine.wordpress.com/a1-and-a2-milk-cows/

A1 and A2 milk cows

There are distinct differences in milk produced by different breeds of dairy cow. A2 cows are descended from ancient breeds more than 5000 years ago. A1 cows are “newer” breeds that have been around for the last 5000 years & have experienced a mutation of a particular amino acid in a protein called beta casein which has a chain of 229 amino acids. A2 cows produce this protein with a proline at position 67, whereas an A1 cow has a mutated proline amino acid which converts to a histidine. The proline has a strong bond to another small protein called BCM 7; which keeps the potentially toxic BCM 7 from being released. But the mutated protein histidine, only weakly holds onto BCM 7 – and then it’s released into the tract of animals & humans who drink it. This is a likely cause of increased phlegm production in digestive & respiratory tract, which can worsen upper respiratory problems – among other problems. The book “The Devil In The Milk: Ilness, Health & the Politics of A1 & A2 Milk” goes into much more detail.



Older breeds such as the Jersey, Guernsey, Asian and African cows are primarily A2 as are goats and sheep. Herds in much of Asia, Africa and parts of S. Europe still produce A2 milk. Black & white breeds like Holstein or Friesians are A1 cows. They’re the most popular breeds in North America, New Zealand, Australia and the rest of Europe.

As tempted as I am to ask pertinent questions/make a remark at this point: note how I don't.





d) More on mutation and age etc



http://www.windsordairy.com/articles/a1-...-milk.html

Keith Woodford, Devil in the Milk author, correctly states that [color="#FF0000"]all European cattle breeds are relatively recent[/color] and the dairy breeds originally all belonged to beta-casein group A2. The point mutations that resulted in subgroups A1, B, and C (not just A1) all include an alteration of proline to histidine at the 67th amino acid in the 209 amino acid chain that is bovine beta-casein. These cows are referred to in shorthand as A1 in the text. These subgroups, but not A2 or A3, would be classified as “bad” according to the theoretical ability to be cleaved and form beta-casomorphine-7, BCM7. Both A2 and A3 gene polymorphisms would then be considered “good” and are called A2.



Lumping these subgroups together, it is unclear that the Jersey, ranging from 50 to 57% “good”, is superior to the Holstein, ranging from 35 to 57% good across 9 studies on 3 continents (see Graph 1). This is because Jerseys range from 33 to 36% B beta-casein and this number must be added to the A1 group to determine what percent have the mutation of concern.



Ranking of European dairy breeds from “bad” to “good” based on a large California study directly comparing American cattle breeds, would be first Holstein, then Milking Shorthorn tied with Jersey, then Brown Swiss and finally Guernsey (see Graph 2). There is a mixture of types within each breed that is consistent across herds and studies. Because of this, Woodford in his book recommends testing of individual animals. If one were to bet on a breed with the “best” beta-casein type it would be the Guernsey with 96% “good” genotype.

(Again, note no comments.)





There may be better links out there, I just picked the first that came by.



There are other reasons - more pressing than "health" - as to why you don't want to be drinking western milk obtained by farms employing certain... dubious practices. (That's only if you care about the kind of four-footed animals that go Moo.) Their ethical standards in this are beyond anything most Hindus will be capable of abiding by. Not all farms, certainly. (Some are against it.) But there exists a practice that is becoming more prevalent now in the milking process/lifecycle in certain western countries (it's common/pioneered in America, I have been told) that is considered profitable and which one could reasonably describe as inhumane.
