==Special Precautions of Kefir==
* According to the University of California Berkeley "Wellness Letter," certain probiotics strains, such as Enterococci, cause problems if you have a weakened immune system or certain bowel problems. The newsletter adds that you should never give probiotics to infants. Also, a 2001 study of kefir in rats found that while kefir treated diarrhea and stimulated immune function in younger rats, it provided neither of those benefits in older rats.
* Sugars : Many kefir drinks have added flavours like vanilla or fruit, but watch out for added sugars that add unnecessary calories. If you want to add some flavour to your kefir, to make it more palatable or just because you enjoy it, either look for store brands without added sugars or artificial flavourings or buy plain kefir and add your own flavourings at home.
