***Milk Kefir: What It Is and How to Brew It

Milk kefir is, to put it lightly, an acquired taste. Sour and pungent, milk kefir is a cultured dairy food originally from the Caucuses – the region where Europe meets Asia. There it has been traditionally heralded as an elixir of long life and health. It seems that there’s wisdom in this tradition: milk kefir is rich in beneficial bacteria, phosphorus, vitamin K, biotin and folic acid – nutrients that are essential to health and well-being. A single component of milk kefir – kefiran – may prove particularly beneficial as it successfully protects beneficial bacteria from damage in the hostile environment of the digestive tract1.
