Quote:I had not heard this term before A1 and A2---- very interesting.If you google A2/A2 milk, you'll find tons of information. But the quick synopsis is, there are 2 types of beta-casein, A1 and A2. This is the same casein that's talked about in gluten-free casein-free diets, and is what causes the intolerance in lactose intolerant people. The research shows that A1 milk is the "potential" cause of a whole host of ailments, diabetes, Crohns, etc. A2 milk is supposed to prevent or potentially cure those ailments(not too sure about "cure" in this statement).
Lots of foreigners say that American milk makes them sick, and it's been linked to the A1 milk produced by Holsteins. Some say it also causes a different taste in the milk.
All goats and human mama's breast milk is A2. That's why kids that are lactose intolerant do good when breast feeding and on goats milk, but not on store bought cows milk(My wife was one of these kids). She also claims that storebought milk has a funny taste, but loves our fresh milk.
Like I said, there's lots of info out there. You'll have to read for yourself and maybe future research will prove one way or the other.
Are goats and sheep both A2?
