I am just finishing this book, "Eating on the Wild Side". It was written by Jo Robinson, who visited Powell's in downtown Portland, and I bought the book personally from her. The main idea is that we have bred our nutrition out of our food in seeking bland, sweet, transportable, reliably productive and identical foods. It is in two main sections, fruits and vegetables. It is absolutely packed with ideas about varieties, history, methods of preparation, storage and serving, and options for improving the nutrition of our foods. It is available at libraries for those patient and cheap souls who don't want to buy the book. I want to hold onto it as a resource. She is from Vashon Island, WA and actually grows the varieties she talks about in her book. She has lists of what types of each species to grow and how. I highly recommend it to anyone who eats lots of fruits and vegetables, which tragically is not most Americans.
I would give it a 9/10 acorns as it made me think deeply about fruits and vegetables and I use the information all the time.
