A few months ago a parent in my classroom gave me some sparkling flavored water. I had tried them years ago and didn't like them, but now that my pallet has been cleared for so long of pop and juice I had a completely different reaction to it = LOVE! I have been treating myself to lots of different brands and flavors ever since. The "natural flavoring" often comes from essential oils. Wondering where essential oils come from? Check out this link for a detailed explanation. The fizzy drink also offers some added minerals for a health boost. Check out this bit of information on one brand. If you haven't tried it recently I would encourage you to do so you may surprise yourself!
