Although this book provides some good basic information on how to develop a gluten free diet, there are some problems. The most glaring are the inaccuracies. In the chapter on foods that do and don't contain gluten, the author states that brown rice has gluten. It does not. In the chapter on eating out, the author states that soy contains gluten. It does not. Many soy sauces, but not all, contain wheat. Also in this chapter the author writes that many Italian restaurants serve polenta and other types of gluten free pasta. Polenta is not a pasta.
Finally, overall, the grammar throughout the book is atrocious. I had significant difficulty finishing this short book because of the constant errors in word usage and poorly constructed sentences.
It was an okay book for free, but I wouldn't invest any money in it.
