My 8 year old has Celiac. She has had severe bowel issues despite removing the gluten from her diet (Ahem... she is 8 and sneaks food... Mommy isn't dumb).
Once we began introducing daily kefir (in the form of a smoothie), she has improved dramatically. This seems pretty simple to us:
Bowel issues from Celiac damage + daily, nourishing, whole milk kefir full of happy bacteria = healthy, habit bowels.
We've decided she will learn all about kefir and its wonders. Then she will make a fabulous display and will serve kefir in a variety of forms (samples of smoothies, herb "sour" cream dip, fruit "cream cheese" spread).
I can't wait to see the finished project. The science fair exhibit is on May 14th, so look for a post shortly after!
