Food choices for lowering sodium intake

A M Altschul, J K Grommet

    Hypertension (Dallas, Tex. : 1979)
    |September 1, 1982
    PubMed
    Summary

    High dietary sodium intake contributes to hypertension, especially with genetic sodium sensitivity. Reducing sodium requires significant dietary changes, focusing on food content and low-sodium alternatives.

    Area of Science:

    • Nutrition Science
    • Cardiovascular Health
    • Public Health

    Background:

    • Excessive dietary sodium intake is a significant nutritional issue in industrialized societies.
    • High sodium consumption, particularly with genetic predisposition, is linked to the development of hypertension.
    • Most dietary sodium originates from both natural and processed foods.

    Purpose of the Study:

    • To highlight the discrepancy between perceived and actual discretionary sodium intake.
    • To emphasize the necessity of substantial dietary modifications for sodium reduction.
    • To underscore the need for accessible information on food sodium content and low-sodium options.

    Main Methods:

    • Analysis of indirect measures of discretionary sodium intake (e.g., salt shaker use).
    • Review of direct measurements of sodium intake in a sample population.
    • Assessment of dietary factors contributing to hypertension.

    Main Results:

    • Indirect measures suggest 25%–50% of sodium intake is discretionary in the US.
    • Direct measurements indicate less than 10% of sodium intake is discretionary.
    • Reducing sodium intake necessitates major dietary changes.

    Conclusions:

    • Individuals needing to lower sodium intake must significantly alter their diet.
    • Availability of information on sodium content in foods is crucial.
    • Low-sodium food alternatives and condiments are essential for dietary compliance.
