Beschreibungen/Notizen

• Osteoporosis is currently defined as “a skeletal disorder characterized by compromised bone strength predisposing a person to an increased risk of fracture. Bone strength primarily reflects the integration of bone density and bone quality” (JAMA 285(6):785–95, 2001). Bone matrix is composed of collagen and other proteins which are mineralized with calcium and phosphorus. Nutritional intake of these proteins, calcium, and phosphorus are obviously needed to provide these important structural components. Nutritional intake of other vitamins and minerals are needed for the cellular processes of bone tissue deposition, maintenance, and repair. In this chapter, we will review the main micronutrients involved in bone growth, remodeling, and repair; but bear in mind that nutrition comprises all nutrients and micronutrients consumed as food, and as such, food is a sum of more than its component parts. Simply supplementing with adequate intakes of the various nutrients does not make a balanced diet, and likely will not have the same benefits. Some micronutrients may be more important to bone than we realize, but separating them out from the diet and focusing on them as a single actor may not be possible. Micronutrients are not drugs and shouldn’t be separated from a balanced diet in practical application. As these are nutrients, the advantage in adding them to a diet will be most beneficial for those with deficiency. For example, adding additional calcium to an already calcium replete diet offers no additional benefit. However, much of the population has inadequate intakes of calcium to build and maintain their skeletons.
