Sources of dietary calcium in patients attending an osteoporosis clinic
Surgical Department, Perth Royal Infirmary, Perth, Scotland
Introduction: Osteoporosis is a common disease that affects both women and men but is more prevalent in postmenopausal women. Reviews suggest that dietary-derived calcium is vital in maintaining adequate calcium balance. Sources of dietary calcium intake among adult patients attending an osteoporosis clinic were reviewed.
Method: Two hundred and ninety-one patients attending an osteoporosis clinic were given an eleven-item food questionnaire to complete. The results were compared to the recommended daily allowance of 700 mg.
Results: The overall mean intake was 657 mg/day with little difference between age or gender. The best foods for supplying calcium were cheese and milky drinks.
Conclusion: This study has confirmed that suboptimal calcium intakes remain common. Dairy sources of calcium remain important. More awareness is needed to convey the importance of dietary calcium and bone health to avoid the development of osteoporosis.
