I am not a gluten expert by any means. I have not searched out books or feel qualified to say which one is better than which other one. There are several books out in the stores about the topic and I suppose that reading about the topic is better than not reading about it. However, when my sister wanted information, she found a book that was so very helpful in explaining what she needed to know. I have read it, and probably should go through it again.
THE GLUTEN CONNECTION by SHARI LIEBERMAN, PhD, CNS
That, my GF friends, is a good read.
