Bone Health and Osteoporosis Vital for healthy bones, the calcium in milk products also contributes to the prevention of osteoporosis. Osteoporosis is a disease characterized by low bone mass and deterioration of bone tissue. This leads to increased bone fragility and risk of fracture, particularly of the hip, spine and wrist.1 People with osteoporosis therefore have a quality of life that is considerably reduced and can end up losing functional independence. In Canada, 1 in 4 women and at least 1 in 8 men over the age of 50 years have osteoporosis. An estimated 2 million Canadians may be at risk of osteoporotic fractures during their lives.2 Early prevention is key! The best strategy for fighting osteoporosis consists in building and maintaining good bone stores from childhood. In fact, there is a lot of evidence demonstrating that higher calcium intakes increase bone gain during growth, postpone age-related bone loss, and reduce the risk of osteoporotic fractures.3 It is well known that milk and milk products represent the most reliable sources of calcium, not to mention other nutrients that contribute to bone health (protein and magnesium, for example). It should be noted that the calcium and vitamin D found together in milk is thought to be particularly important for bone health, since vitamin D improves the absorption of calcium, which is the building blocks of solid bones. Moreover, certain studies show that the calcium in milk products could be better for bone health, and possibly the prevention of osteoporosis, than calcium supplements.4 Sources Osteoporosis Canada Jackson SA et al.

Osteoporoza je degenerativni poremećaj kostiju koji karakterizira stanjivanje i slabljenje kostiju uslijed čega one postaju osjetljivije na lomove i prijelome. Svaka treća žena starija od 50 godina pretrpjet će prijelom kralježnice ili prijelom kuka, kao posljedicu osteoporoze koja ne pogađa samo žene, već je ugrožen i svaki šesti muškarac. Na osteoporozu ne postoji lak odgovor jer je riječ o složenoj bolesti koja uključuje hormonske, prehrambene i čimbenike iz okoliša. Iako lijeka nema, vježbanje, ishrana i dopune mogu pomoći u zaustavljanju daljnjeg gubitka koštane mase. Prehrana bogata kalcijem, zajedno s vitaminom D koji pomaže apsorpciju kalcija u tankom cijevu, bitna je za spriječavanje osteoporoze. Fluor je bitan mineral jer stvara zubi i kosti, a ima ga u plodovima mora. Magnezij je jednako kao i kalcij potreban za očuvanje zdravlja kostiju, a bor, zajedno s spomenutim mineralima, jača kosti. Vitamin D nalazi se u mnogim mliječnim proizvodim, a proizvodi ga i sama koža izložena sunčevoj svjetlosti. On je neophodan za apsorpciju kalcija.
