Understanding the IDDSI Framework
The International Dysphagia Diet Standardisation Initiative (IDDSI) is a global project that developed standardized terms, definitions, and testing methods for modified foods and liquids. The framework consists of a continuum of eight levels, from 0 (Thin) to 7 (Regular), identified by numbers, text labels, and color codes. This standardization is crucial for communication between healthcare professionals, caregivers, and individuals with dysphagia, ensuring consistency and safety. The purpose is to provide clear guidance on modifying food and drink texture to reduce the risk of choking and aspiration (food or liquid entering the lungs).
What is a Level 3 food? The Liquidised Diet Explained
IDDSI Level 3 is designated for liquidised foods, which are defined by their smooth, homogenous texture with no 'bits' or lumps. These foods require no chewing and are swallowed directly. The consistency is similar to a thick, smooth pudding or yogurt. The thickness allows the individual more time to control the food in their mouth and throat, making swallowing safer.
Characteristics of Level 3 foods include:
- Consistency: A smooth, cohesive texture with no lumps, fibrous parts, or particles.
- Portability: Can be eaten with a spoon or drunk from a cup.
- Flow: Drips slowly in dollops from a fork and cannot be eaten with one, as it would fall through the prongs.
- Structure: Cannot be piped, layered, or molded, and spreads out if spilled.
- Preparation: Foods are blended with nutritious fluids such as gravy, milk, or cream to achieve the correct, smooth consistency.
What is an example of a Level 3 food?
Examples of meals and items that can be prepared to a Level 3 consistency include:
Savoury Meals
- Thick, creamy soups (e.g., blended butternut squash or creamy tomato soup)
- Liquidised casseroles or stews (made with chicken or beef, blended with thick gravy)
- Liquidised macaroni and cheese or spaghetti bolognese
- Creamed or liquidised flaked fish with a sauce
- Blended corned beef hash
Breakfasts
- Smooth, well-soaked porridge, blended until lump-free
- Blended breakfast cereal (e.g., wheat biscuits) with warm milk
- Smooth, full-fat yoghurt with blended, seedless fruit
Desserts
- Smooth milk puddings (semolina, ground rice)
- Mousse or instant whip desserts
- Smooth custard or fruit fool
- Crème caramel or smooth cheesecakes (filling only)
How to prepare Level 3 food
Achieving the correct liquidised consistency is vital for safety. Preparation methods involve:
- Blending: Using a high-speed blender or food processor to purée foods until completely smooth. Blend in small batches to ensure a uniform texture.
- Moistening: Adding a rich, flavorful liquid during blending, such as milk, cream, broth, or gravy. This enhances flavor and nutrient density while achieving the right consistency.
- Straining: After blending, push the food through a fine sieve to remove any remaining lumps, skins, seeds, or fibers.
- Testing: Perform the IDDSI Fork Drip Test. The food should drip slowly in dollops through the fork prongs, not hold its shape. For liquids, use the IDDSI Flow Test to ensure the appropriate thickness.
How Level 3 Differs from Other IDDSI Levels
Understanding the differences between IDDSI levels is key to safe swallowing, particularly distinguishing Level 3 (Liquidised) from its neighbours. Level 3 food is completely smooth, whereas higher levels introduce some texture or chewable pieces.
| Feature | IDDSI Level 3 (Liquidised) | IDDSI Level 4 (Pureed) | IDDSI Level 5 (Minced & Moist) |
|---|---|---|---|
| Texture | Completely smooth, no lumps | Smooth, moist, cohesive; holds shape | Soft, moist with lumps (max 4mm adults) |
| Chewing | Not required | Not required | Minimal chewing required |
| Eating Method | Spoon or cup | Spoon only | Fork or spoon |
| Flow Test | Drips slowly in dollops from fork | Holds shape, does not flow through fork | Holds shape, does not flow through fork |
| Example | Blended soup or custard | Thick mashed potato | Cottage pie filling with gravy |
Nutritional Considerations for a Level 3 Diet
While a liquidised diet ensures safety, it can sometimes lead to reduced nutritional intake because of a smaller appetite or quicker satiety. To combat this, it is important to fortify meals with extra calories and protein. This can be done by:
- Using full-fat dairy products (milk, cream, cheese) instead of low-fat versions.
- Adding ingredients like butter, margarine, or olive oil during blending.
- Enriching milk with dried milk powder for extra protein and calories.
- Including high-calorie fruits like avocados, or blending pureed fruit with cream.
- Encouraging frequent, smaller meals and nutritious snacks throughout the day.
- Regularly monitoring body weight to ensure stable intake.
Tips for Maximizing Enjoyment of a Level 3 Diet
A liquidised diet doesn't have to be bland or unappetizing. With some creativity, meals can remain enjoyable and visually appealing.
- Focus on Flavor: Experiment with herbs, spices, soy sauce, or curry powder to create robust and varied flavors.
- Use Colorful Ingredients: Create visually appealing plates by using colorful purees. For instance, a vibrant carrot purée next to a green spinach purée.
- Serve at the Right Temperature: Ensure hot foods are served hot and cold foods are served cold to maximize enjoyment.
- Incorporate Fortified Drinks: Use nutritious, moderately thick beverages like milkshakes or smoothies to supplement calorie intake between meals.

Conclusion: Safe Swallowing and Satisfying Nutrition
In summary, what is an example of a Level 3 food? It is any food or drink that has been processed to a liquidised, smooth, and lump-free consistency, allowing for safe consumption by individuals with dysphagia. The IDDSI framework provides clear, international standards that help prevent choking and aspiration, while careful preparation and fortification ensure that nutritional needs are met. By focusing on both safety and enjoyment, caregivers and individuals can manage a liquidised diet successfully, improving quality of life and ensuring satisfying mealtimes.
