Major Knowledge Gaps 15 A.II.06 Investigations should include epidemiological studies of the interrelationships between calcium intake and fracture risk, osteoporosis, prostate cancer, and hyper tension must be pursued to determine if calcium intake is an independent determinant of any of these health outcomes. Control of other factors potentially associ ated as other risk factors for these health problems is essential (for example, fat intake in relation to cancer and cardiovascular disease; weight-bearing activity; and dietary components such as salt, protein, and caf feine in relation to osteoporosis)
