Insights
Thickened liquids help children with swallowing disorders (dysphagia) but commercial thickeners have drawbacks. This study found that smooth pureed foods can effectively thicken liquids, offering a viable alternative for managing pediatric dysphagia.
Area of Science:
- Pediatric Medicine
- Speech-Language Pathology
- Food Science
Background:
- Children with dysphagia face risks like respiratory issues and poor growth.
- Thickened liquids aid swallowing but commercial thickeners present challenges in taste, texture, and cost.
- Alternative methods for thickening liquids are needed for pediatric dysphagia management.
Purpose of the Study:
- To investigate the efficacy of commercial pureed foods in thickening liquids for children with dysphagia.
- To compare the properties of puree-thickened liquids with traditional starch and gum-based thickeners.
- To assess puree-thickened liquids as a potential alternative for managing pediatric swallowing disorders.
Main Methods:
- Utilized the International Dysphagia Diet Standardisation Initiative (IDDSI) flow test for all thickened liquid samples.
- Conducted rheology testing to measure viscosity and yield stress of thickened liquids at varying conditions.
- Compared liquids thickened with smooth purees, gum-based agents, and cornstarch-based agents.
Main Results:
- Liquids thickened with smooth pureed foods demonstrated comparable results to commercial starch and gum-based thickeners.
- The IDDSI flow test and rheology testing supported the effectiveness of puree-thickened liquids.
- Puree-thickened liquids showed potential as a viable alternative to conventional thickening agents.
Conclusions:
- Smooth-textured pureed foods can be effectively used to thicken liquids for pediatric dysphagia.
- This method offers a promising and potentially more compliant alternative to commercial thickeners.
- Further research may validate puree-thickening as a standard intervention for swallowing difficulties in children.
Abstract:
Children with dysphagia, or swallowing disorder, are at an increased risk for developing respiratory compromise, failure to thrive, and aversion. Thickened liquids can be recommended for children with dysphagia, if shown to be effective on instrumental examination and if strategies/interventions with thin liquids are not successful. Thickened liquids have many benefits, including creating a more cohesive bolus, slowing oropharyngeal transit time, and reducing aspiration. However, preparing thickened liquids with commercially available thickeners can result in poor compliance due to concerns regarding taste, texture, accessibility, cost, thickness variability, and potential negative impact of these substances on a child's immature digestive tract. The purpose of this study was to determine if liquids could be successfully thickened with widely available, commercial pureed foods, and to assess how these mixtures compare to starch and gum based thickening agents. The International Dysphagia Diet Standardisation Initiative (IDDSI) flow test was performed for each sample of puree thickened liquids, gum based thickened water, and cornstarch based thickened water. In addition, rheology testing was performed on each category of the samples to measure viscosity at various shear rates and temperatures, and to assess the presence of yield stress. Results revealed that liquids thickened with smooth textured purees were comparable to commercial starch and gum based thickeners, and may be offered as a viable alternative.
