Abstract:
A well-performed and large intervention study by Iuliano et al. showed that protein and calcium supplementation via regular dairy products reduces the risk of fractures and falls in vitamin D replete older adults in aged care facilities. The study was performed in Australia, which raises the question whether their intervention might also be effective in aged care facilities in the Netherlands. Intake levels of protein and calcium are comparable between Australian and Dutch older adults. A higher protein intake, for example from dairy, is associated with higher muscle mass, muscle strength and bone density. Iuliano et al. showed that with accessible, regular food products, relevant health outcomes can be improved. These results are relevant for Dutch older adults as well. Future research should investigate whether sustainable dairy substitutes can be just as successful.

Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
Essential Minerals for Bone Health
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
