Effects of an Arabinoxylan-enriched Rusk on Postprandial Glucose, Insulin, Glucagon-like Peptide-1 and Appetite Responses

Overview

The aim of the present pilot randomized controlled trial is to compare the effects of the following: 1)-rusk enriched with arabinoxylans (r-rich), 2)-rusk not enriched (r-standard) on blood glucose, insulin values, glucagon like peptide (GLP-1) and appetite scores in 10 healthy volunteers.

This is a double-blind, randomized crossover trial. A rusk product enriched with arabinoxylan extracted from threshing residues, hereafter referred to as r-rich, was developed to evaluate its effects on postprandial metabolic responses and satiety compared with the standard product, referred to as r-standard. Ten healthy adult Caucasian non-smoker volunteers were enrolled starting from October 2025. Participants received both products in a computer-generated randomized sequence, with a washout period of at least 72 hours between test sessions. On each test day, after an overnight fast, participants underwent baseline blood sample collection and anthropometric measurements, including body weight and height. They then consumed 100 g of the assigned product within 20 minutes while seated. Blood samples were collected at 20, 60, 90, 120 and 180 minutes after product consumption.
