This book contains good solid information and could absolutely really help improve the health of a lot of people.
This book was good, but not as good as the book on this topic by Dr Sherry Rogers which I found far more thorough. That book was excellent and so I would recommend it over this one. If all your library has is this book however, it is well worth a read and makes many important points.
Also worth reading are books on the SCD eating plan and the GAPS diet, if you have serious gut issues and dysbiosis and need to heal your gut. These books take a very different and diet-based approach, that may be even more beneficial for some people.
