Modification of stool content by increased bran intake

M H Floch, H M Fuchs

    The American Journal of Clinical Nutrition
    |October 1, 1978
    PubMed
    Summary

    Adding crude fiber to the diet significantly increased stool volume in healthy adults. However, it did not alter fecal pH, water content, or bacterial counts, though the anaerobic to aerobic bacteria ratio may increase.

    Area of Science:

    • Human Nutrition
    • Gastroenterology
    • Microbiology

    Background:

    • Dietary fiber intake is a crucial factor influencing gut health and function.
    • Understanding the impact of specific fiber types on fecal characteristics and gut microbiota is essential for dietary recommendations.

    Purpose of the Study:

    • To investigate the effects of crude fiber supplementation on fecal parameters and gut bacteria in healthy individuals.
    • To assess changes in fecal weight, water content, pH, and bacterial populations (aerobic and anaerobic) following increased crude fiber intake.

    Main Methods:

    • A controlled study involving six healthy subjects over 8 weeks.
    • Dietary history, daily crude fiber intake monitoring, and weekly 72-hour stool collections were performed.
    • Stool analysis included fecal weight, water percentage, pH, and qualitative/quantitative aerobic and anaerobic bacterial counts.

    Main Results:

    • Crude fiber supplementation (5.4 g/day, increasing intake to at least 10 g/day) significantly increased stool volume.
    • Fecal pH, water percentage, and solid content remained unchanged during high-fiber intake compared to control periods.
    • No significant changes in qualitative or quantitative aerobic and anaerobic bacterial counts were observed, but the anaerobic to aerobic ratio appeared to increase.

    Conclusions:

    • Increased crude fiber intake effectively enhances stool volume in healthy adults.
    • Crude fiber supplementation does not significantly alter fecal water, solids, or pH.
    • While overall bacterial counts are unaffected, a potential shift in the anaerobic to aerobic bacterial ratio warrants further investigation.
