There have been reports implicating A1 protein/BCM-7 in negative health effects like Ischaemic heart disease, Type 1 diabetes, autism, inflammatory response and digestive discomfort etc, but the scientific community believes the evidence is insufficient and inconclusive.
In fact European Food Safety Authority (EFSA) in 2009 did not find "cause and effect" relationship between BCM-7 and the reported non-communicable diseases. Since 2009, more research was done on gastrointestinal effects of A1 and BCM-7.
The overall evidence for gastrointestinal effects from A1 and BCM-7 in animal and in vitro studies is conclusive, but the evidence from human studies is still limited.
Despite the lack of conclusive scientific evidence from human studies, several players have started marketing A2 milk with claims that it is natural, better, and free from negative effects.
