Osteoporosis is a common disease of the elderly, affecting women much more than men. It causes thin, brittle bones that break easily. You know all those little old ladies with broken hips? Nearly all have osteoporosis.
The standard prescription for prevention is weight-bearing exercise on a regular basis, and adequate intake of calcium and vitamin D. The aforementioned blog post rejects the calcium recommendation, at least.
I haven’t reviewed this issue for many years and I just discovered Happy Healthy Long Life, so I have no opinion on validity of the post.
