For anyone who has ever been accosted by angry vegetarians, we recommend this book - although it won't be too shocking to anyone familiar with Weston A Price findings, we gather it's quite a challenge for vegetarians and particularly vegans.
While
we wouldn't give it a 100% rave review - at times when it gets into
topics other than nutrition it goes off the rails (for example the graph
on page 251 referring to climate is one of the most meaningless charts ever published!), but it's very entertaining and well
written, as well as a scary insider account of what veganism really does to people - well worth reading.
