Response: Previous studies have shown that higher milk intake is associated with higher bone mineral density. In one of our previous studies, we reported that higher dairy food intake was protective against bone loss especially among older adults who used vitamin D supplements. Older adults are at high risk of vitamin D deficiency because recommended intakes are difficult to achieve without fortified foods (such as dairy) or supplements. Vitamin D stimulates calcium absorption, which is beneficial for building bones. However, it is unclear if the effect of vitamin D on calcium absorption is substantial enough to translate into beneficial effects on bone. Therefore, the current study determined the association of dairy food intake with bone health. We further examined whether these associations would be modified by vitamin D status. (more…)
