I was actually given this book by my ob-gyn (yes he is awesome) after being diagnosed with gestational diabetes. The advice on nutrition during pregnancy is excellent. I used this as my guide because I was on a restricted diet, and I felt great after following their advice. They also are very thorough about covering pretty much any question you can imagine. Be warned though, some of their advice is extremely difficult to follow. Only eating raw sugar is hard as many products contain white, processed sugar that you would not expect. Basically, it is hard for anyone to eat perfectly, pregnant or not. Yet, this book can help you create a nutritional plan that is as close to perfect as possible. These authors are detail oriented and leave nothing to chance- I consider this book to be a must have for all expectant mothers!
