Hi Linda
According to the celiacs I know, psyllium husk is already an important part of their diet, because one of the things celiacs can suffer from is a lack of fibre in their diet.
When you make wheat bread, the gluten in the wheat reacts with the yeast to make the bread rise. Celiacs can't process gluten in their system, so there has been a long and intensive search for a product which will mimic gluten's reaction with yeast. Usually they have to put up with "bread" that is basically cake, and needs to be toasted in order to taste anything like real bread. Over the past few years, tapioca starch was hailed as the solution, but this tends to produce loaves which are soggy in the middle, because the tapioca flour holds a lot of liquid. Psyllium husk is the latest in a long line of substances, and seems to be working the best so far in creating a loaf which best mimics "real bread".
There is a lot more info at Dan Lepard's Q & A on gluten free bread :
