Osteoporosis is the weakening of bones with age. It can turn minor falls into medical trauma. For women especially, it is important to take steps to minimize it. Appropriate, healthy diet is one key preventative measure. Calcium is important for bone health, but vitamin D and magnesium are similarly important. Exercise is also important to avoidance of osteoporosis: it should be regular, and should be weight-bearing. While more commonly a problem for women, men are not immune to the threat of osteoporosis.
