Actually Milk and all diary products commercially produced in the world is not healthy. As most are from Jersey/Holestine which are Genetically modified Cows.

But then there is no other choice... :-(

Maybe Goat milk... or camel milk

Milk from Indian Gir cow breed produces the healthiest milk. It has hump on its shoulder like an Oxen. It produces an average of 10 Ltrs where as Jersey produces 50ltrs milk daily.

Today its difficult to find Gir cow breed in India.
