Pectin: an examination in normal subjects

L A Gold, J P McCourt, T J Merimee

    Diabetes Care
    |January 1, 1980

    Summary
    This summary is machine-generated.

    Dietary pectin did not affect blood glucose or insulin when taken with glucose alone. However, pectin did lower blood sugar levels when consumed with a mixed meal, without impacting insulin secretion.

    Area of Science:

    • Nutrition Science
    • Metabolic Studies

    Background:

    • Pectin is a soluble dietary fiber with potential metabolic effects.
    • Understanding pectin's impact on glucose and insulin is crucial for dietary recommendations.

    Purpose of the Study:

    • To investigate the effect of pectin on serum glucose and insulin concentrations.
    • To determine if pectin's effects differ when administered with glucose versus a mixed meal.

    Main Methods:

    • Administration of pectin (10 g) with glucose (100 g) to normal subjects.
    • Administration of pectin with a standard mixed meal.
    • Measurement of serum glucose and insulin concentrations.

    Main Results:

    • Pectin with glucose alone did not significantly alter serum glucose or insulin.

  • Pectin with a mixed meal reduced glycemia but did not significantly alter insulin secretion.
  • 18-day pectin supplementation with meals had no effect on serum glucose or insulin.

    • Conclusions:

    • Pectin's effect on glucose metabolism may depend on the accompanying food matrix.
    • Pectin may help modulate postprandial glycemia in the context of a mixed meal.
    • Short-term pectin intake does not appear to chronically alter glucose or insulin homeostasis.
