Type of Milk (A1/A2) and Human Health Attributes:A Review

Cow milk is a source of micro-nutrients required for good health. Now a days, a new debate on type of milk and its possible effect on human health has started, some people says that A2 milk is more beneficial for health than Al milk. As the milk and milk products are essential components of human diet, hence the present paper reviews studies conducted on type of milk and human health. Al allele is more frequent in exotic cattle while Indian breeds of cattle and buffaloes have A2 allele. Some of the studies on consumption pattern of Al/A2 beta-casein and human health have shown that A2 milk is beneficial for health; however, more detailed investigations are required to prove the hypothesis that Al milk could facilitate the immunological process that leads to health problems in humans.
