Talk about soda that's actually healthy. Kefir is an ancient drink prepared using cultured grains of bacteria and yeast. These grains can be purchased online. The activated cultures can be used to prepare the kefir ,then reused again. The drink gets slightly fizzy like soda when fermented.
Kefir is usually prepared with milk ,but the water kefir is much lighter and better choice for those who are lactose intolerant.
Water Kefir can be flavored with any fresh fruits or juices with hint of fresh ginger. Drink one cup twice a day for a healthy gut.
