When I found out I had diabetes I bought this book and a few more. One that I do like is the Moosewood Restaurant Low Fat Favorites. The difference between the two is that Moosewood takes commonly available at any grocery store foods, and combines them into new and very delicious entrees. Joslin's book (supposed to be gourmet, but I didn't really think it was) often calls for hard to find ingrediants and the results are really not worth the effort.I have since eliminated diabetes from my health problems and am medication free. This book did not help. If you need one for a basic diabetic guide, choose the Moosewood Low fat favorites. It is really good.
