[Modification of glucose resorption by bulk materials].

Area of Science:

• Nutritional Science
• Metabolic Research
• Pharmacology

Background:

• Glucose absorption significantly impacts metabolic health, particularly in individuals with diabetes.
• Ballast substances are known to influence gastrointestinal transit and nutrient absorption.
• Understanding the effects of specific ballast substances on glucose metabolism is crucial for dietary and therapeutic strategies.

Purpose of the Study:

• To investigate the impact of two ballast substances, supercol (galactomannan) and manucol (sodium alginate), on glucose resorption.
• To compare the effects of these substances against a control (glucose only) and a placebo.
• To evaluate the efficacy of supercol and manucol in modulating blood glucose levels in healthy individuals and different diabetic groups.

Main Methods:

• Randomized controlled trial involving 40 participants, divided into four groups: healthy, diet-controlled diabetics, maninil 5 diabetics, and B-insulin diabetics.
• Oral glucose tolerance test (OGTT) administered with 100g glucose.
• Inclusion of 20g of supercol, manucol, or placebo in the glucose solution for specific experimental groups (B, C, and D, respectively).
• Blood glucose levels monitored for 120 minutes post-ingestion.

Main Results:

• Supercol (galactomannan) administration resulted in unequivocally lower mean blood glucose curves in both non-diabetic and all diabetic groups compared to the control and placebo groups.
• Manucol (sodium alginate) showed a trend towards decreasing mean blood glucose curves, but the effect was not statistically significant.
• The study demonstrated that supercol significantly retards glucose resorption.

Conclusions:

• Supercol (galactomannan) is an effective ballast substance for retarding glucose absorption, leading to lower postprandial blood glucose levels.
• The findings suggest potential benefits of supercol in managing blood glucose excursions in healthy individuals and diabetic patients.
• Manucol (sodium alginate) did not demonstrate a significant impact on glucose resorption in this study, warranting further investigation.
