Selenium content of enteral formulas.

R F Martin, V R Young, M Janghorbani

    JPEN. Journal of Parenteral and Enteral Nutrition
    |March 1, 1986
    PubMed
    Summary

    Selenium levels in enteral formulas vary significantly. Egg albumin-based formulas offer high selenium, while others may fall below recommended intake, necessitating supplementation.

    Area of Science:

    • Nutritional Science
    • Biochemistry
    • Analytical Chemistry

    Background:

    • Enteral nutrition is crucial for patients unable to consume food orally.
    • Selenium is an essential trace element vital for numerous physiological functions.
    • Ensuring adequate selenium intake through enteral formulas is critical for patient health.

    Purpose of the Study:

    • To quantify the selenium content in various enteral formulas and modular components.
    • To compare selenium levels against established safe and adequate intake ranges.
    • To inform recommendations for selenium supplementation in enteral nutrition.

    Main Methods:

    • Neutron activation analysis (NAA) was employed for precise selenium determination.
    • Analysis covered both complete enteral formulas and modular enteral components.
    • Data were systematically collected and compared to dietary reference intakes.

    Main Results:

    • Enteral formulas utilizing egg albumin as a primary ingredient exhibited the highest selenium concentrations.
    • A majority of the analyzed enteral formulas contained selenium levels below the proposed safe and adequate range.
    • Significant variability in selenium content was observed across different product formulations.

    Conclusions:

    • Egg albumin-based enteral formulas are a rich source of selenium.
    • Many commercially available enteral formulas may not provide sufficient selenium to meet patient needs.
    • Consideration of selenium supplementation is recommended for enteral formulas with suboptimal selenium content to prevent deficiencies.
