One personally confirmed case, but I read the above mentioned book, that examined thousands of studies, and the author described her own situation how she reversed her bone density, and then I recommended the book to my friend who was just confronted with her own bone density loss. She has a scientific background and actually she is quite skeptical of various quack recipes, but the book and the approach seemed well founded, so she took it seriously and followed the recommendations in the book and after one year she repeated the lab test, and to her delight the results about the bone density reversal were better than expected and very encouraging. Also physically she feels better than before.
On the other hand, I know a few other ladies, who keep eating dairy and meat, and they all have deteriorating bones and joints. So as far as I can see, there seems to be a certain correlation between consumption of dairy and bone problems. That is only my personal observation, but more importantly, I read other materials that documented the adverse results of dairy consumption, and regrettably, on the other hand I witnessed several medical professionals still recommending the alleged benefits of milk, that's why a real case of someone I know and trust is more reliable for me than the TV milk ads and guidelines of the National Dairy Council.
After getting her lab results, my friend now spoke to several of her friends, who value her knowledge, reputation, and judgment, and at least one of them already ordered that book. Maybe next year, she'll be able to supply more evidence, but in the meantime, you can read the book extract on the Amazon site, or borrow the book from your library, so you can review it yourself.
