If you have a milk allergy, using A2 milk won't make any difference, as its still a caesin protein.

The main difference between A1 and A2 milk is that when its digested, the caesin protein chain breaks at a different point and forms different compounds during digestion.

Most of the cows used in our dairy farming are A1 cows. I can't remember the exact percentages, but about 10% of our normal dairy cows are A2. In herds of A2 cows, they genetically test the cows to make sure they are certified A2.

Anyway, to cut a long story short, A2 milk has been researched for its possible role in reducing cardiovascular disease, diabetes and skin conditions.
That's not quite true Vicky, A1 milk is linked to cardiovascular disease, diabetes and autism, however A2 milk doesn't reduce the conditions, rather its not known to be a factor in the creation of them. The A2 company is spending a lot of money on marketing to make people believe it is medicinal, whereas in reality it is more likely to be neutral rather than beneficial.

This conclusion was reached (actually the reason they 'found' A2 milk) because it was noted that people in Japan and other countries which don't have a lot of dairy in their diets had a lower risk of heart disease and diabetes. But it was also noted that the people of Greenland (or Iceland, can't remember which), had a lot of dairy in their diets, but they were low in heart disease and diabetes aswell. So the scientists looked into it and found that the cows of Greenland were predominantly genetically different to others, being A2 caesin protein producers.


I think that my eldest has a milk intolerance, and as a family we don't drink cows milk at all anymore (we drink rice milk). When I read up on A2 milk I thought it might be what we need, but after 3 days on it, we saw the degradation of DDs behaviour, so we took her back off it. Unrelatedly I went to see her teacher after 2 days at school and she jumped on me and asked what was wrong with her.....she had been out of control. I explained the trial and she just smiled, nodded and said "Um...yeah....can you please not give her milk anymore??". She was diagnosed ADD at 6 years old and was on Ritalin for about 2 years, but has no need for it at all being off cows milk......however even the A2 milk triggered the bad behaviours in her. The A2 company claims that A2 milk is linked to a decrease in autism and hyperactivity, but from my experience it's the protein itself, not the form of it which is the issue.
