The other day, I was advised to try Kefir (which I had never heard of). I bought some and strangely enough (for me) enjoyed it.

It has the appearance of milk and the consistency of diluted yogurt. It's described as a "probiotic fluid" on the label...I certainly don't know what that means...

So, the question is:
  • Why is this not better known?
  • Is there a downside to it?


I'm having a very "bad back" week and it was my acupuncturist/chiropractor that suggested I introduce this into my diet.
