[Prevention of systemic osteoporoses and osteoporomalacias]

Evaluating previous findings and own experience, the author tries to develop new starting points for the prevention of systemic osteoporoses including disturbances in mineralisation. Here, a life-long physical activity for the establishment of a large bone mass is just as important as a sufficient isolation ensuring the satisfaction of an increased demand for vitamin D, sufficient supply of protein and minerals and the substitution of an estrogen deficiency.
