Understanding Your Nutrition Diet: What level of IDDSI is pureed?

According to research published in 2022, tailored interventions focusing on IDDSI can significantly improve meal compliance and staff knowledge in aged care facilities. This demonstrates the importance of the IDDSI framework, which clarifies what level of IDDSI is pureed and other modified textures to ensure safety for individuals with swallowing difficulties.

Quick Summary

Pureed food is classified as IDDSI Level 4, representing a smooth, lump-free texture that requires no chewing. This diet is essential for people with dysphagia, ensuring adequate hydration and nutrition while minimizing choking risk.

Key Points

• Pureed is IDDSI Level 4: The pureed diet corresponds to Level 4 in the IDDSI framework, standardized globally for dysphagia management.

• Requires No Chewing: IDDSI Level 4 food is smooth and lump-free, prepared to be swallowed directly without the need for chewing.

• Texture is Moist and Cohesive: Level 4 food holds its shape on a spoon but is moist and easily slides off, and it must not be sticky.

• Tested for Safety: Caregivers can use simple tests, like the Spoon Tilt Test and Fork Drip Test, to verify the food's consistency and safety.

• Fortification is Key for Nutrition: Because pureed diets can sometimes be less calorically dense, adding ingredients like full-fat dairy or butter can help boost protein and energy.

The International Dysphagia Diet Standardisation Initiative (IDDSI)

The International Dysphagia Diet Standardisation Initiative (IDDSI) was established to create a globally recognized framework for describing texture-modified foods and thickened liquids. Before IDDSI, different facilities and regions used inconsistent terminology, which led to confusion and compromised patient safety. The IDDSI framework consists of a continuum of eight levels, ranging from Level 0 (Thin liquids) to Level 7 (Regular foods), with specific tests for each level to ensure consistency and accuracy. These standards are critical for providing safe and effective nutritional care to individuals with dysphagia, or swallowing disorders. The framework is designed to be person-centred, acknowledging that a person might be able to tolerate more than one level safely, giving them a greater variety of food choices.

What level of IDDSI is pureed?

The answer is straightforward: pureed food corresponds to IDDSI Level 4. This level is represented by the color green and is characterized by a thick, uniform, and smooth consistency. Pureed food should be moist and cohesive, meaning it holds its shape on a plate or spoon but is not sticky. It requires no chewing and is prepared to be swallowed directly. Importantly, liquids must not separate from the solids in a Level 4 food. This level is connected to Extremely Thick Drinks (also Level 4) on the IDDSI framework because they share similar flow characteristics, though they are prescribed independently.

Characteristics of IDDSI Level 4 (Pureed)

• Smooth and Lump-Free: The food must have a completely smooth consistency with no visible lumps or pieces. This is typically achieved using a food processor or blender.
• Moist and Cohesive: The texture should be moist throughout. It should hold its shape when scooped but slide off a spoon easily when tilted.
• Not Sticky: The food must not be sticky, as this increases the risk of it adhering to the mouth or throat, which can be a choking hazard.
• No Chewing Required: This is a crucial feature, as a pureed diet is intended for individuals who have difficulty chewing or controlling food in their mouth.
• Holds its Shape: The food should form a mound or pile on a plate and not spread out excessively.

Who needs an IDDSI Level 4 diet?

An IDDSI Level 4 diet is recommended by a speech pathologist or other healthcare professional for individuals with severe dysphagia. The diet is particularly beneficial for those with:

• Reduced tongue control: Difficulty in moving food to the back of the mouth for swallowing.
• Poor or no chewing ability: This can be due to neurological conditions, missing teeth, or poorly fitting dentures.
• Painful swallowing: A pureed texture can be less painful to swallow than coarser foods.
• Inability to form a bolus: The pureed consistency is pre-formed and ready for swallowing, eliminating the need for the individual to manipulate it in their mouth.

How to Test for IDDSI Level 4

To ensure food meets the IDDSI Level 4 standard, caregivers and food service staff can perform simple tests. Temperature is an important factor, as it can alter consistency.

The Spoon Tilt Test:

1. Scoop a spoonful of the food.
2. Hold the spoon at a tilt or lightly flick it.
3. The food should be cohesive enough to hold its shape on the spoon but slide off easily with minimal residue left behind.

The Fork Drip Test:

1. Place a small amount of food on the tines of a fork.
2. The food should sit in a cohesive mound and not continuously drip or flow through the tines.

Nutritional Considerations for a Pureed Diet

While a pureed diet is safer for swallowing, it presents nutritional challenges. The process of pureeing can sometimes reduce the nutrient density if liquids like water are added, and individuals with small appetites may not consume enough volume.

How to Boost Calories and Protein

To prevent malnutrition and ensure adequate energy intake, food fortification is recommended. Examples include:

• Adding full-fat dairy: Stir in full cream milk, double cream, or cheese to pureed dishes, soups, and porridge.
• Using butter or margarine: Mix into mashed potatoes, vegetables, or sauces to increase caloric content.
• Incorporating milk powder: Add dry milk powder to milk-based drinks and meals to boost protein and calories.
• High-protein alternatives: Use pureed beans, lentils, or tofu mixed with sauces for extra protein.

Ensuring Adequate Hydration

Individuals on pureed diets may also need thickened fluids, but this is assessed separately from food textures. It is important to ensure proper hydration with a variety of appropriate beverages, such as milkshakes, soups, or nutritional supplements, thickened to the required IDDSI fluid level.

Delicious and Nutritious Pureed Meal Ideas

A pureed diet doesn't have to be monotonous. With creativity, meals can be flavorful, visually appealing, and nutritionally dense.

• Breakfast: Smooth, lump-free porridge made with full-cream milk and a scoop of milk powder, topped with pureed fruit.
• Lunch: Creamy, thick pureed soup with no lumps, fortified with cream or cheese.
• Dinner: Pureed chicken casserole or shepherd's pie, with the meat and vegetables blended with a thick, smooth sauce or gravy. Serve with pureed, fortified mashed potatoes.
• Snacks/Desserts: Set fruit yoghurts, fruit mousses, or instant puddings.

Foods to Avoid on an IDDSI Level 4 Diet

To ensure safety, certain foods must be completely avoided as they pose a significant choking or aspiration risk.

• Hard or Dry Foods: Examples include nuts, raw vegetables, and crackers.
• Mixed Textures: Any food with both thin liquid and solid pieces, such as soup with lumps or cereal with milk that separates.
• Stringy or Fibrous Foods: This includes celery, pineapple, and some cuts of meat.
• Sticky or Gummy Foods: Foods like nut butter or overcooked oatmeal can stick to the mouth and throat.
• Foods with Husks, Skins, or Seeds: Such as corn, grapes, or berries with seeds.
• Crumbly Foods: Dry biscuits or cake crumbles.

Frequently Asked Questions

What is the difference between IDDSI Level 3 and Level 4?

IDDSI Level 3 (Liquidised) is thinner than Level 4 (Pureed). Level 3 pours quickly and cannot be piped or molded, while Level 4 is thick enough to hold its shape on a spoon or plate.

Who benefits most from an IDDSI Level 4 pureed diet?

Individuals with severe dysphagia benefit most, including those with reduced tongue control, poor chewing ability, or painful swallowing. It is prescribed by a speech pathologist or other healthcare provider.

How can I make pureed food more appetizing and flavorful?

Use herbs, spices, and flavorful liquids like gravies, stocks, or juices instead of water when blending. Pureeing foods separately and plating them individually can also preserve flavor and color.

Are pureed fruits and vegetables safe for an IDDSI Level 4 diet?

Yes, as long as they are properly prepared. This means removing all skins, seeds, and tough fibers before pureeing them to a smooth, lump-free consistency.

Can I use store-bought baby food for an IDDSI Level 4 diet?

Some strained baby foods may be appropriate, but they should always be checked against the IDDSI guidelines for Level 4 using the Spoon Tilt and Fork Drip tests to ensure they are the correct consistency.

What happens if pureed food is too thick or sticky?

If pureed food is too thick or sticky, it can increase the risk of it adhering to the mouth or throat, which is a potential choking hazard. It is important to add enough liquid to achieve the correct moist, cohesive texture.

Does food temperature affect IDDSI compliance?

Yes, food temperature is critical for IDDSI compliance. For example, some chilled foods may pass the Fork Drip test, but become thinner at room temperature and fail. Testing should always be done at the intended serving temperature.
