• Throughout the life cycle the skeleton requires optimum development and maintenance of its integrity to prevent fracture. 
  • Bones break because the loads placed on them exceed the ability of the bone to absorb the energy involved.
  • It is now estimated that one in three women and one in twelve men older than 55 years will suffer from osteoporosis in their lifetime.
  • Diet plays an important role in the acquisition and maintenance of bone mass. 
  • The influence of diet on bone begins in childhood; even maternal diet can influence bone mass in the offspring. 
  • A good general nutritional status and adequate dietary protein, calcium, vitamin D, fruits, and vegetables have a positive influence on bone health, while a high caloric diet and heavy alcohol consumption have been associated with lower bone mass and higher rates of fracture. 
  • The evidence for a role of other minerals and vitamins in skeletal health is not as strong, but recent evidence suggests that vitamins C and K might also have an effect on bone.
