Concerns about bone disorders, especially osteoporosis, of humans has stimulated interest in calcium, phosphorus and magnesium nutrition and metabolism. Calcium has received the most attention, and intakes are now being recommended at levels difficult to achieve, up to 1500–2000 mg/day. These recommendations are made despite evidence indicating that massive intakes of calcium do not prevent bone loss (1), and that certain population groups with a low incidence of osteoporosis consume relatively low amounts of calcium (2). Thus, we decided to examine the possible effects on major mineral metabolism of some dietary substances other than cholecalciferol, calcium and fluoride; these substances were aluminum, magnesium and boron. |
