What is the IDDSI Framework?
The International Dysphagia Diet Standardisation Initiative (IDDSI) provides a global standard for describing modified food textures and thickened liquids. Developed by a team of international experts, the framework offers a consistent and evidence-based approach to dietary recommendations for individuals with dysphagia, or swallowing difficulties. The IDDSI framework uses an eight-level continuum, identified by numbers (0-7), text labels, and color codes, to ensure clear communication among healthcare providers, caregivers, and patients. This helps prevent serious health complications, such as aspiration pneumonia and dehydration, by ensuring liquids and foods are at the right consistency for safe consumption.
Understanding IDDSI Level 1: Slightly Thick
IDDSI Level 1 is classified as 'Slightly Thick' and is the first level of thickened liquids in the framework. This consistency is thicker than thin liquids (Level 0), like water or juice, but thinner than Mildly Thick liquids (Level 2). For individuals who have difficulty controlling the flow of thin liquids, a Slightly Thick consistency provides better control during swallowing.
Characteristics of IDDSI Level 1
Slightly Thick liquids have several key characteristics:
- They are noticeably thicker than water but still flow easily.
- They can typically be consumed from a standard cup or with minimal effort through a straw.
- The consistency is validated using the IDDSI Flow Test, where a 10 mL syringe is filled and allowed to flow for 10 seconds. For Level 1, between 1 mL and 4 mL of liquid should remain in the syringe.
What is an example of IDDSI level 1?
Several common beverages naturally fall into the Slightly Thick category, while others can be modified to achieve the correct consistency. This allows for variety and improved adherence to dietary guidelines.
Naturally occurring examples include:
- Some fruit nectars: Apricot, pear, and mango nectars often have a viscosity that aligns with Level 1.
- Tomato juice: The natural thickness of tomato juice can place it within the Level 1 range.
- Certain milks with fat content: Some dairy and non-dairy milks have a slightly thicker texture than water.
Other drinks can be prepared to reach a Slightly Thick consistency by adding a thickening agent, such as a commercially available powder or gel. Examples of liquids that can be thickened include:
- Water
- Coffee and tea
- Fruit juices
- Milkshakes
- Nutritional supplements like Ensure Plus
Preparing and Testing IDDSI Level 1 Liquids
To ensure safety, it is essential to prepare and test Level 1 liquids correctly. The process involves adding a specified amount of thickening agent to a liquid and allowing it to set, as the final consistency can be affected by factors like temperature and fat content.
Practical steps for preparing thickened liquids:
- Start with a clean, dry cup. Add the recommended number of scoops or sachets of thickener powder, following the product instructions.
- Add the liquid to the powder quickly while stirring briskly with a fork or whisk for approximately 30 seconds.
- Allow the liquid to stand for the time specified by the thickener manufacturer, as some thickeners continue to develop consistency after mixing.
Verifying Consistency with the IDDSI Flow Test
To confirm the correct Level 1 consistency, the simple and effective IDDSI Flow Test can be performed at home.
- Fill a 10mL syringe (plunger removed) to the 10mL line, with your finger covering the nozzle.
- Remove your finger and allow the liquid to flow for exactly 10 seconds.
- After 10 seconds, cover the nozzle again and measure the amount of liquid remaining in the syringe. For a Level 1 liquid, the remaining liquid should be between 1 and 4 mL.
Comparison of IDDSI Liquid Levels
To illustrate the differences, here is a comparison table of IDDSI liquid levels.
| Characteristic | Level 0: Thin | Level 1: Slightly Thick | Level 2: Mildly Thick | Level 3: Moderately Thick |
|---|---|---|---|---|
| Appearance | Flows like water | Thicker than water | Pours quickly but slower than thin | Pours slowly like honey |
| Drinking Method | Cup, straw, syringe | Cup, straw | Cup, straw with effort | Cup, spoon, wide straw with effort |
| IDDSI Flow Test | <1 mL remaining after 10 seconds | 1-4 mL remaining after 10 seconds | 4-8 mL remaining after 10 seconds | 8+ mL remaining after 10 seconds |
| Natural Examples | Water, juice, broth | Fruit nectar, tomato juice | Milkshakes, thickshakes | None common |
Nutritional Considerations and Professional Guidance
For individuals with dysphagia, maintaining hydration and nutrition is a primary concern. Dehydration can exacerbate health issues, and difficulty swallowing can lead to reduced food and fluid intake. Slightly Thick liquids can improve fluid intake by making drinking safer and more appealing than thicker alternatives. However, it is vital to work with a healthcare professional, such as a speech-language pathologist or a registered dietitian, to determine the appropriate IDDSI level and dietary plan. They can assess the individual's specific needs, recommend the correct consistency, and provide guidance on preparing and verifying thickened liquids safely.
Conclusion
For those requiring modified liquid consistencies due to dysphagia, understanding what is an example of IDDSI level 1 is a fundamental step toward safer swallowing. Slightly Thick liquids, including naturally occurring ones like fruit nectars or water thickened with a powder, offer a valuable consistency that is easier to control than thin liquids, promoting better hydration and overall nutritional well-being. Always consult with a healthcare professional to determine the most appropriate IDDSI level for individual needs, and use the IDDSI Flow Test to ensure the correct and safe consistency. The global adoption of the IDDSI framework has made it easier than ever to communicate and manage dysphagia diets effectively, ensuring patient safety and quality of life.
