My pal Sarah bought some coconut water kefir from Tonix at Whole Foods. Kefir is good for the intestines and immune system. It was pretty tasty, but she thought it'd be even better in some juice - and she was right. She used my lovely Omega 8003 to juice carrots, oranges, and apple, and then mixed it with the kefir. It was really delicious, but gave us a bit of a headache (we were probably experience a little detox).
If you're looking for a great juicer, I highly recommend the Omega. It's easy to clean, quiet, and low heat - it can even juice wheat grass.
