While the author could perhaps be clearer about some of the ingredients she recommends (spelt, alternative milks), I think this is a great book for those of us who suffer from food allergies. I myself have found spelt to be a safe alternative to wheat, and I only tried it after reading her book, as others had told me it would have the same effect as wheat. Each person's allergic reaction seems to be different, so to write a book that will be useful for all is difficult, but I think that Dumke's book comes as close as possible to doing this.
