Have you noticed that whenever you go to the doctor with a sniffle or some other minor symptom it seems like you are getting a prescription for antibiotics? This may be one of the reasons we need the benefits of kefir.
All of the antibiotics that are prescribed for various ailments not only kill unhealthy bacteria; they kill good bacteria as well as the bad bacteria. This is one of the reasons that many people don't have enough of the good bacteria in their systems. Kefir, yogurt, cheese and pickles are all good for adding the good bacteria to our systems, but if we cut back on the antibiotics then maybe we won't have to be as concerned with probiotics of any kind.
