Xylitol is a diabetic friendly sweetener that looks and tastes much like sugar.  It has less calories than sugar and is absorbed by your body as a sugar alcohol.  There are well documented studies that say it is also good for your teeth as it prevents acid from harming your teeth and causing cavities.  

According to many different articles, it is safe for children and pregnant women.  There is nothing that I have read about it that says otherwise.
