title: [Osteoporosis and nutrition].
abstract: Although nutrition accounts only for a small percentage of bone mass, it is essential for reaching and maintaining peak bone mass and for preventing accelerated bone loss with age. Calcium, proteins, and vitamin D are the best investigated nutrients, protein- and vitamin D-deficiency becoming frequent with advancing age, vitamin K, trace elements, and phosphorus having additional effects. Excessive intake of animal proteins leads to bone loss via acidotic stimulation of osteoclastic bone resorption, and high salt intake enhances negative calcium balance by increasing renal calcium losses. Dairy products offer an equilibrated Calcium and protein intake, but have to be monitored for their fat content. Adequate nutrition in childhood influences positively bone mass in adulthood, while nutritional supplementation in elderlies can even increase bone mass.
