A2 milk – the origins and the science
It appears that many years ago – more than 1000 by most assessments – some cows had a natural genetic mutation in which a specific beta-casein (milk protein) changed from the A2 protein to an A1 protein.
No one really knew about it at the time, obviously.
In the late 1900’s, New Zealand researcher and entrepreneur, Corran McLachlan, began studying the A1 beta-casein in milk.
McLachlan’s research “concluded a strong link between the consumption of the A1 beta casein protein and Ischaemic heart disease, childhood Type 1 diabetes and other ailments, and he believed that many people thought to have lactose intolerance are instead sensitive to the A1 protein.”
One could reasonably suggest, at this point, for people sensitive to the A1 protein in cow’s milk to switch to drinking goat, sheep, or water buffalo milk from small, local farms since these other types of milk have almost exclusively the A2 protein.
But that would be too easy.
This is where McLachlan’s solution came into play: “using a genetic test, McLachlan was able to identify cows that produce only the A2 protein. McLachlan's conclusions were not accepted among all scientists; many pointed out that the research was ‘correlative, rather than proven cause and effect’” (Wiki)
But, the test was patented and the implications had started: ordinary, untested cow milk was dangerous.
One of the best ways to scare people into new buying patterns is to give them serious concern about disease. In this case, heart disease, type 1 diabetes and a general intolerance to milk caused by mysterious, unknown factors.
So what is the exact science behind these claims?
