At the time of the first edition, this book was the best thought out and researched of all. The concept of protein complements, among others, is crucial to making a vegetarian diet work for any length of time. I tried to work with several others, and still have their books which I use occasionally. This one has stuck we me over three continents and as many decades. In times when I wasn't totally vegetarian it still provided a welcome change and a reminder that I wasn't reliant on the local meat market. Of all the books this has the philosophy and practicality to stay with one as a viable guide to a vegetarian lifestyle.
With this edition my wife and children have discovered, for quite different reasons (one from concerns about ecology, pollution, additives, GMOs, etc., the other from a more 'economic manipulation of peoples food habits' as well as nutrition) this book once again and found it as relevant now. They were thunderstruck to see my yellowed, fingermarked, and well-worn, copies with notes of variations I had tried. The beauty of the open-ended concept here is understated, but crucial. It has given us a stronger nutritional base as well as contributed to our growth as a family.
For someone new to this area this contains some of the most sound nutritional, philosophical, and economic, reasoning I've seen in print. Over time it becomes quite easy to adapt conventional recipes to the methodology in this book. As a guide for your cuisine and your life it is very good indeed.
