There are lifestyle guidelines, nutrition assistance programs, food labeling information, and even tips on healthy restaurant eating.
If you've ever thought you might be interested in growing mushrooms, whether for your own use or for market, Growing Gourmet and Medicinal Mushrooms by Paul Stamets (Ten Speed Press, 2000) is the source to use for all you need to know. It is not a guide for wild collecting, but rather for the cultivation of mushrooms. Stamets gives a complete rundown of all the common and many of the not-so-common mushrooms that you might not even be familiar with. After reading this book, you will come away as a mushroom enthusiast, like it or not!
