Just FYI-
Been doing a ton of research on immune response in general, and of course, in cf in particular. There is a ton of research to support that S. thermophilus is a no-no in cf. It is an activator of the Th2 response in the body....this as the immune response in cf that we want to tun off not on!!!! Most standard yogurts use s.themophilus in the fermenting process.... While I do believe that if you have no fermented foods in your diet, yogurt is a great start, you are actually MUCH better off by taking a probiotic without s.thermophilus in it.
Culturelle is a great one and Jarrow-dophillus EPS is also very good.
If you choose to take a probiotic with S. thermophilus in it, be very careful to select one which shows the amount of CFU (colony forming units). There should be much less of it than any other strain of probiotic.
Unfortunately, my computer won't work at my dad's so all of my research is stuck on that one....I will poat next week as far as the research goes.
ALSO!!! The latest CF JOURNAL in Europe (of course) researchers tested intestinal flora in baby cfers as well as adults. Right off the bat, the baby cfers (even those never on ABs) had a much too acidic environment....there intestinal flora was so messed up and included bugs that were not seen on the controls. No amount of yogurt is going to normalize intestinal flora that out of whack..... supplementation is the only way to repopulate the gut. And, because the cf gut is so inhospitable to friendly bacteria, it is so important to take a probiotic daily to keep it colonized.
Look at it this way, healthy people struggle to keep their intestinal flora in balance. High sugar foods, birth control, antibiotics, steroids,standard american diet (processed foods no whole foods) all contribute to a ph in the gut that is too acidic for the good bacteria to thrive. Now, look at a cf person. CF Newborns who have never been exposed to these things already have a problem...now, add all the crap we have to take, not to mention the CRAP they tell us to eat and we are are going to experience many problems due to the lack of good bacteria....ie. inflammation, yeast, c.diff...and that is just to name a few.
When the intestinal flora is off, the immune sytem is immediately impaired....gut health is directly related to lung health.
The study also went on to show that all cfers in the study had a form of crohns disease....
what do cf and crohn's have in common....? low glutathione, little or no lactic acid producing bacteria (probiotics)
that is all I have for now...since I can't post the study.
take care.
