Query: Osteoporosis Prevention

This book has a SOME good information. HOWEVER, this important information is assimilated by a layperson, not a medical expert who works with patients and emerging research on a daily basis. The book is poorly presented and edited. MUCH better books are "Osteoporosis for Dummies," "Reversing Osteopenia," and "Action Plan for Osteoporosis." Most importantly, be sure and discuss your questions with a medical specialist--don't rely on any of these books to self-diagnose or self-treat. The author's gem and personal analogies fall flat and are distracting in this book.P.S. Like the author, I am a patient with osteoporosis, a writer, and have done extensive research on the subject.
