Metabolic chromium balances in men.

E G Offenbacher, H Spencer, H J Dowling

    The American Journal of Clinical Nutrition
    |July 1, 1986
    PubMed
    Summary

    This study found that older men absorb very little dietary chromium (Cr), with most being excreted in stool. The body appears to maintain chromium balance despite low absorption rates.

    Area of Science:

    • Human Nutrition
    • Trace Element Metabolism

    Background:

    • Chromium (Cr) is an essential trace element involved in carbohydrate and lipid metabolism.
    • Understanding chromium absorption and balance is crucial for assessing nutritional requirements and potential deficiencies.

    Purpose of the Study:

    • To quantify chromium absorption and balance in healthy older adult males.
    • To determine the net retention and excretion of dietary chromium.

    Main Methods:

    • A 12-day chromium balance study was conducted on two healthy males (ages 62 and 66) consuming a constant diet.
    • Complete daily urine and stool collections were analyzed for chromium using Zeeman atomic absorption spectrometry.

    Main Results:

    • Dietary chromium intake averaged 36.8 micrograms/day.
    • Apparent net absorption of chromium was low, averaging 1.8% (0.5-0.9 micrograms/day absorbed).
    • The majority of ingested chromium was excreted in the stool, with minimal urinary excretion.

    Conclusions:

    • Healthy older males exhibit very low apparent net absorption of dietary chromium.
    • Chromium balance appears to be maintained through homeostatic mechanisms despite limited absorption.
    • Further research is needed to elucidate the precise role and requirements of chromium in aging populations.
