What is the International Dysphagia Diet Standardisation Initiative?
IDDSI is a global, not-for-profit initiative that created a standardized framework for describing texture-modified foods and thickened liquids. The development of the IDDSI framework was crucial because varying terminologies for dysphagia diets previously led to confusion and increased risks like choking and aspiration pneumonia. IDDSI provides a universal language for healthcare providers and caregivers, ensuring consistent and safe meal practices for individuals with dysphagia.
The initiative was established in 2013 by international experts with the goal of developing an evidence-based, practical system for describing food texture and drink thickness. The framework was first released in 2015 and has gained widespread adoption globally.
The IDDSI Framework: A Continuum of Levels
The IDDSI framework uses an 8-level continuum (0-7) with numerical levels, text labels, and color codes to classify liquids and foods. Drink levels range from 0 to 4, while food levels span from 3 to 7, with levels 3 and 4 covering both categories.
IDDSI Drink Levels
- Level 0: Thin (White): Standard thin liquids.
- Level 1: Slightly Thick (Grey): Thicker than water, flows faster than mildly thick.
- Level 2: Mildly Thick (Pink): Flows slower than slightly thick, can be sipped from a cup with effort.
- Level 3: Moderately Thick (Yellow): A drink, eaten with a spoon; cannot be sipped.
- Level 4: Extremely Thick (Green): Cannot be sipped, eaten with a spoon, holds shape like puréed food.
IDDSI Food Levels
- Level 3: Liquidised (Yellow): Smooth, lump-free, homogeneous; same as Moderately Thick liquids.
- Level 4: Pureed (Green): Smooth, uniform, lump-free, holds shape; no chewing required.
- Level 5: Minced & Moist (Orange): Soft, moist, easily mashed with a fork; defined lump sizes (4mm for adults, 2mm for children).
- Level 6: Soft & Bite-Sized (Blue): Soft, moist, tender food pieces (1.5 cm for adults, 8mm for children); requires some chewing.
- Level 7: Regular (Black): Normal, everyday foods, including "easy to chew" options.
Practical Testing Methods for IDDSI Levels
IDDSI includes simple, objective tests to verify food and drink consistency, ensuring consistent preparation under serving conditions.
- IDDSI Flow Test: Uses a 10 mL syringe to measure liquid flow rate over 10 seconds to classify liquid thickness.
- IDDSI Fork Pressure Test: Used for food Levels 5-7 to check how easily food squashes or holds shape when pressed with a fork.
- IDDSI Fork Drip and Spoon Tilt Tests: Used for levels 3-5 to assess cohesiveness and viscosity by observing how food/drink behaves when tipped or dripped.
The Nutrition Diet Connection: How IDDSI Aids Dysphagia Management
Managing dysphagia involves not just modifying textures but also ensuring adequate nutrition and hydration. The IDDSI framework assists in creating safe and appealing meals that meet nutritional needs.
- Enhanced Safety: Standardized textures reduce the risk of choking and aspiration.
- Better Nutritional Intake: Consistency standards support fortification of modified foods and liquids to address malnutrition and dehydration.
- Greater Food Variety: The framework allows for varied and enjoyable diets within safe consistency levels.
IDDSI vs. Outdated Terminology
IDDSI replaced inconsistent and subjective terms used previously. The table below shows the key differences:
| Outdated Terminology (e.g., NDD) | IDDSI Framework Levels | Key Differences & Improvements |
|---|---|---|
| Thin Liquids | Level 0: Thin | Consistent terminology across all settings. |
| Nectar Thick | Level 2: Mildly Thick | IDDSI adds a Level 1 ('Slightly Thick') for more subtle modifications. |
| Honey Thick | Level 3: Moderately Thick | IDDSI provides objective, practical testing methods like the Flow Test for verification. |
| Pudding Thick | Level 4: Extremely Thick | Explicitly describes texture for safety, distinguishing from other consistencies. |
| Chopped, Ground, Mechanical Soft | Levels 5 & 6: Minced & Moist and Soft & Bite-Sized | IDDSI standardizes particle sizes (e.g., 4mm for Minced & Moist) to reduce choking risk. |
Conclusion
In summary, what does IDDSI stand for? It represents the International Dysphagia Diet Standardisation Initiative, a vital global framework for establishing clear, consistent, and safe nutrition diets for individuals with dysphagia. By standardizing terminology and offering practical testing methods, IDDSI enhances patient safety and nutritional care worldwide. Its adoption facilitates consistent research, improved training, and ultimately, a better quality of life for those with swallowing difficulties.

Benefits of a Standardized Approach
The standardized IDDSI framework offers significant advantages for patients, caregivers, and healthcare systems. It improves communication, ensuring dietary needs are consistently understood across various care settings. Clear definitions and tests enhance training for staff, reducing preparation errors. The standardized approach also supports more reliable research on dysphagia management and ensures consistent care for patients who travel.
Implementation and the Future
Implementing IDDSI requires a collaborative effort involving organizational support and comprehensive staff training. Many countries and professional organizations have endorsed and are implementing the framework. Its continued adoption is a major advancement in standardizing dysphagia care and prioritizing patient safety in nutrition diet management.
