Dietary needs for bone health and the prevention of osteoporosis

Osteoporosis is identified as a painful, disabling and disfiguring health deficit that is entirely preventable given early detection and reversal of the causes--one of which is deficiency of nutrients required for bone health. The notable examples of nutrients where deficiency is directly related to the onset of osteoporosis are identified as calcium and vitamin D. The reasons why deficiency occurs are analysed in this article and high-risk situations for deficiency identified and discussed. The use of phytooestrogens in dietary prevention of osteoporosis is explored to include analysis of foods containing phytooestrogens, the quantities required, and product variability. Given the increasing role of phytooestrogens in dietary prevention of osteoporosis, discussion in this section looks at the need for food labelling, including phytooestrogen content, so that consumers can make reasoned choices as to the quantities they require and the dietary sources from which this will be obtained.
