Final answer:
A postmenopausal woman not on hormone replacement therapy should consume 800 mg of elemental calcium daily to maintain bone health and prevent osteoporosis. Calcium absorption decreases after menopause due to lower estrogen levels, hence diet and supplements play a critical role in meeting the calcium requirement.
Step-by-step explanation:
It is essential for postmenopausal women, especially those not on hormone replacement therapy, to maintain adequate calcium intake to prevent osteoporosis and maintain bone health. After menopause, the absorption of calcium decreases due to a drop in estrogen levels, which can increase the risk of developing osteoporosis and related fractures. Based on the guidelines, a postmenopausal woman who is not taking hormone replacement therapy should aim for an intake of 800 mg of elemental calcium daily. This can be achieved by consuming calcium-rich foods like dairy products, green leafy vegetables, and supplements if necessary.
Calcium-rich foods and supplements are crucial for reducing the risk of fractures and maintaining bone density. Estrogen levels, which impact calcium metabolism, decrease after menopause, and without replacement therapy, dietary calcium becomes even more important. Including calcium-rich foods in the diet or taking supplements can help meet the daily requirements and improve overall health.
