I bought water kefir (pronounced keh-FEER, not Kiefer as in Kiefer Sutherland) grains to make naturally carbonated soda pop because I prefer the drinks not just with unprocessed sugar but also with low sugar content. Initially I was hesitant to try because I was worried I might get candida/yeast infection and other skin ailments from drinking it but I read that the grains don't have the same candida yeast and may actually help in its cure for those who suffer from it.
