Kefir: Kefir is a live and active cultured dairy product with a mildly tart and tangy taste and creamy in consistency. It is an enzyme-rich food filled with friendly micro-organisms that help balance your “inner ecosystem.” More nutritious and therapeutic than yogurt, it supplies complete protein, essential minerals, and valuable vitamins. It originated over 2000 years ago in the Caucasus Mountains and is associated with good health.
