My ob had never heard of kefir! I guess I shouldn't be surprised. I basically told him what it was and he said that's fine. He said just stay away from unpasteurized soft cheeses from Mexico!
I went to the Whole Foods today for the 1st time in over 2 years; it's so far from my house but I just figured out it's only a few minutes from my doctor (I drive pretty far for that because I REALLY like my doctor!). All I bought was some kefir, strawberry-banana flavor. I figured that would be a good way to get started for now. I've NEVER liked yogurt so I'm not sure I"ll like the taste of this, but I figure I can always use it in place of milk when I make milkshakes or smoothies. If we decide to make homemade kefir it'll be a while from now after we finish summer vacation. The stuff I bought only has 10 varieties of microorganisms, so a far cry from the 30+ that is supposedly found in the homemade. But for now this might be a better sell with dh, since it's been refrigerated (at least after it was bottled, anyway), as opposed to me leaving milk sitting out on the counter for 24 hours! It's hard getting used to new ideas! Anyway, thanks for all the great info.
