About one third of the milk proteins are beta caseins and their breakdown on digestion create different biological activities. And A1 and A2 are the prominent types of Beta caseins of which A2 is thought to be the original Beta casein produced by the ancestors of the present day dairy cattle. The studies worldwide have shown that A2 Beta casein rich milk is likely to reduce the risk of heart disease and Type 1 childhood diabetes. It is also believed that the digestion of A2 Beta caseins does not produce proteins linked to worsening of autism symptoms.
