Calcium, phosphorus, and osteoporosis

H H Draper, C A Scythes

    Federation Proceedings
    |July 1, 1981

    Summary

    Calcium intake is crucial for bone health, especially with Western diets. Adequate calcium (Ca) intake can help prevent bone loss in middle adulthood and inhibit osteopenia in postmenopausal women.

    Area of Science:

    • Nutritional Science
    • Gerontology
    • Bone Metabolism

    Background:

    • Epidemiological data show no direct correlation between national calcium (Ca) supply and aging osteopenia rates.
    • Previous findings that Ca supplementation fails to reverse osteoporosis led to the belief that Ca nutrition is not a significant factor in osteoporosis etiology.

    Purpose of the Study:

    • To investigate the role of calcium (Ca) nutrition in osteoporosis, considering dietary variations.
    • To evaluate the adequacy of Ca intake in different populations and its impact on bone health.

    Main Methods:

    • Analysis of epidemiological data on osteopenia rates and national Ca supplies.
    • Review of studies on Ca administration and its effects on bone loss.
    • Comparison of Ca requirements based on different dietary patterns (e.g., Western vs. cereal-based).

    Main Results:

    • Ca intake adequate for low-protein, alkaline diets may be insufficient for high-protein, acidic Western diets.
    • Ca administration has shown efficacy in inhibiting postmenopausal osteopenia.
    • Epidemiological evidence suggests liberal Ca intake reduces bone loss in middle adulthood.
    • Low Ca intake is a concern for middle-aged individuals, particularly women, in the US and Canada.
    • A Ca:P ratio above 1:2, influenced by low dairy and high phosphorus intake, may increase bone loss risk.

    Conclusions:

    • Dietary context significantly influences calcium (Ca) requirements for bone health.
    • Maintaining adequate Ca intake and an appropriate Ca:P ratio is essential for preventing bone loss, especially in aging populations consuming Western diets.
