Is it ok to eat malted barley it is one of the ingredients in the organic water crackers.

Yes: Barley is a healthy grain. Malting is a process that increases the sugar in it so malted barley adds some sweetness to the crackers. Crackers tend to be converted primarily into sugar once you digest them anyways so the malted barley is almost like predigesting some of the grain.
