Associations between dietary intake and volumetric bone mineral density in South Asian and Caucasian women: preliminary analysis of the D2–D3 Study

In the diet, few foods naturally contain vitamin D(2). [...]the majority of the UK population rely on sunshine as their main source of vitamin D which is problematic since during the months of Oct–Mar in the UK, the angle of the sun results in UVB rays that are not at optimum length (290–320 nm) to penetrate the skin and allow vitamin D production. When focusing on vitamin D, the comparison of tertiles of vitamin D intake and the association with vBMD found no clear relationship for either group. Consideration of the impact of age, menopausal status and body composition upon bone health outcomes for both SA and CA women is also a priority.
