Re: Goat's Milk (A1 vs A2 beta-casein protein research)

[Guest guest]

I've been doing research on casein lately because I wanted to ease my son back

onto it (after years of GF/CF his gut is pretty much healed) in an effort to

expand his diet and catch him up on the growth charts.

In Australia and New Zealand you can buy A2 milk, which has a slightly different

beta-casein protein conformation. It doesn't cause BCM7 to be released into the

body. When BCM7 ends up in the bloodstream (in cases if leaky gut) it binds to

the opiate receptors in the brain. It has been proven that BCM7 is found in the

urine of ASD kids and not in NT controls after ingesting regular A1 milk.

A1 is a mutation that crept into the cow gene pool in the last 1,000 years and

most of our regular Holstein/Friesian dairy cows are predominately A1. The

original/ancient gene is actually A2. Goats milk is totally A2, probably sheep

too. Older breads of cows that have not been crossbred are A2 - like yak and

perhaps buffalo/bison. Guernsey and Jersey have a higher percentage of A2 genes

in their population as they we isolated on islands during the time A1 was

infiltrating the european gene pool.

It's been known for years that there is a difference between the two beta-casein

proteins and that BCM7 from A1 beta-casein has a negative neurological impact on

people with leaky gut. It's only just coming into the public eye now since

" Devil in the Milk " by Woodford was published late in 2007.

There is a chemical compound similar to BCM7 from gluten as well and when one

meets up with a partner from A1 casein they create exponential mayhem. THAT is

why the combination of GF AND CF works for so many people. The book didn't

mention an alternate gluten protein option, so I'm going to continue the gluten

free diet till I get more information on that angle.

I hope to hear researchers and doctors talking about this at the next DAN

conference in the USA - it's really exciting stuff. I only drink raw milk from

Jersey cows now myself and I have been giving my son imported raw sheep and

goats milk cheese with no adverse reactions (with HN Peptizyde) for a couple of

months.

Notice I said RAW. There are indications that milk proteins are altered/damaged

during the pasteurization process so the body doesn't recognize them as food and

mounts an immune attack - but thats a whole other story.

There is no source of pure, certified A2 cows milk in california at the moment,

but perhaps we'll see it sometime in the future. I'm looking into the location

of the few dairy farms in the USA who are rumored to be converting their herds.

It takes 10 years of selective breeding to get the A1 gene out of mixed stock,

so I hope they started a while ago!

The A2 corp of NZ has patents on the gene testing process and have trademarked

" A2 Milk " so unfortunately it's not a case of asking your local dairy farmer if

he has an A2 cow you can milk...... ;-)

It will be interesting to see where it goes from here - A1 beta-casein is

implicated in heart disease, type 1 diabetes and schizophrenia too. This is just

the beginning.

Hi ,

I recently read the book " Devil in the Milk " by Dr Woodford (published

2007) and it was full of corporate intrigue and governmental

cover-up's in addition to very informative scientific data.

Professor McLachlan died in 2003, so if he was the one you were trying

to contact - I guess he did disappear off the face of the earth.... ;-)

I'm Australian, but have lived in California for the last 20 years.

When I went home for Christmas my sisters teenage kids were drinking

A2 milk. She said one was " less snotty " and the other was " less brain

foggy " than when drinking regular milk. I immediately thought immune

activation and opioid receptors! Which started me on this path of

casein research. I thought my son would never be able to have dairy,

and here he is now eating raw sheep and goats milk cheese with no

problems!

I'm going to send my copy of the book to s. She's a

clinical nutritionist who speaks at all the DAN conferences and has

indicated strong interest in the information. I hope she will talk to

the other doctors about this at the next DAN conference and get some

more attention on subject.

I was also considering e-mailing Dr Houston to ask about how he thinks

Peptizyde enzymes interact with A1 and A2 proteins. It would be good

to know if there is a difference in the bio-chemical reaction between

the two. Has anyone had communications with him about this? I don't

want to bother him if it's a topic already addressed.

I did a bit of research last night and found that certified A2 is

produced by one single herd in Nebraska at Prairieland Dairy. The milk

is available in mid-western states at " Hy-Vee " stores (which I have

never heard of since I'm in the FAR west). Here is the link for anyone

interested: http://www.a2milk.com/index.htm

They can't say that regular A1 milk is BAD for legal reasons, but

people can google it and get some of the information found in the book.

Personally I'm not going to have it shipped in, because it's

pasteurized. But if people don't have a problem with that, then give

it a go! I'm going to search high and low for a small dairy farm in

California who are converting their herds. Perhaps I can get a cup of

unpasteurized to try.....

If there are any new developments I'll certainly post it to the group. At the

moment I'm happy sticking with raw sheep and goat milk cheeses, but it would be

nice to get access to unpasteurized A2 cows milk in the future.

I know there are a lot of people who just can't bring themselves to try GF/CF

with their kids, so this would be a secondary option for those living in the

mid-western states where A2 milk is available.

Going to head to the post office today to send the book to s.

Hopefully she will have time to read it before speaking at the next DAN

conference. Other doctors and researchers should REALLY be looking at A1

beta-casein proteins and the connection to autism.

Here is 's website if anyone is interested:

http://www.nourishinghope.com

There is a lot of good biochemistry information, in addition too nutrition/diet.

P.S. I'll e-mail Dr Houston as soon as I get time. I'm in crunch mode at work

and there are only so many hours in the day......
