Purpose: The aim of the study was to determine the gastrointestinal (GI) tolerability of drinks and foods thickened with a gum-containing thickener compared to a starch-based thickener in patients with dysphagia.
Design: A randomized, double-blind, controlled, parallel group study.
Methods: Subjects started with a 3-day run-in period on a starch-based thickener and continued with a 14-day intervention on either the starch-based or gum-containing thickener.
