While this book adequately covers the usual topics for a book on osteoporosis, there is a bit of misinformation that is so huge that, as you can see, I gave the book one star. This is misinformation that is repeated over and over, typically from the traditional medical establishment, and also from under-informed journalists.
The author seems to think that the only hormone to replenish depleted progesterone in menopausal women is progestin. Wrong! Progestin is the synthetic drug used in the WHI trials, and was for years the "synthetic progesterone" of choice of MDs until those study results were released. However - it is easy and inexpensive to use natural progesterone, which is chemically the same as what your body produces, and chemically different from the synthetic progestin. The author then goes on to cite increased risks of cancer from hormone therapy. Well, yeah, when you use synthetic chemicals, common sense tells us that's probably not the best idea. There are hormonal therapies that use chemically-identical compounds, but the profits do not accrue to the pharmaceutical companies, so they continue to brainwash physicians against them.
This is a huge disservice to women and is incredibly irresponsible misinformation peddling. Please, do some research on the topic. Read every book you can find on menopause (osteoporosis will be covered, as will many other important topics) and realize that many books by MDs will make the same mistake this author does - but many others will not. You have to learn for yourself to recognize when misinformation is being given. Progestin is not natural. Progesterone is. Estrogen plus progesterone is what your body produced when you were young and healthy. They are not suddenly poisonous after your 50th birthday. (Whereas, apparently, the synthetics traditionally prescribed by MDs are.)
Everyone is different, and every woman needs to make up her own mind. But please, do it with the correct information, and not the brainwashing of the pharmaceutical industry.
