Like it says: recommended. This is where to start.

Every other week we will offer a review of one or more books, some from the reading list above, some from further afield. Check back often for the latest, or search the archive.

We will be compiling a database of abstracts from current scientific research that support the principles we promote and the validity of our mission. Without specific permission from the copyright holders, we cannot publish the full articles, but some of these articles can be purchased online, and those of you with access to a university library could spend a rainy afternoon in the stacks perusing back issues of soil science and nutrition journals... Enjoy!
