Understanding Nutrition: What is an example of a Level 2 diet?

According to the International Dysphagia Diet Standardisation Initiative (IDDSI), a framework used globally, dysphagia diets are categorized into eight levels to ensure patient safety. The Level 2 diet, also known as a mechanically altered diet, is an important intermediate step for those transitioning from pureed textures back to more solid foods.

Quick Summary

A Level 2 mechanically altered diet features soft, moist foods that are easy to chew and swallow. It is typically prescribed for individuals with dysphagia who can tolerate some texture but need modified food for safety. This diet serves as a transitional stage between pureed and advanced textured foods.

Key Points

• Definition: A Level 2 diet, also known as a mechanically altered diet, consists of moist, soft, and finely minced foods.

• Purpose: It is designed for individuals with dysphagia who can chew minimally but require texture modification for safer swallowing.

• IDDSI Alignment: Under the International Dysphagia Diet Standardisation Initiative (IDDSI), this corresponds to Level 5, or 'Minced and Moist'.

• Food Preparation: Foods must be cooked until tender, finely chopped or mashed, and mixed with extra moisture from sauces or gravies.

• Examples: Typical meals include moistened ground meats, mashed potatoes, and soft-cooked vegetables.

• Foods to Avoid: Tough meats, dry breads, crunchy cereals, nuts, seeds, and fibrous vegetables should be avoided.

What is the Purpose of a Level 2 Mechanically Altered Diet?

A Level 2, or mechanically altered, diet is specifically designed for individuals experiencing mild to moderate dysphagia, which is a medical term for difficulty swallowing. This diet is a critical step for patients who can manage some texture but are not yet ready for regular solid foods. The primary goal is to minimize the risk of choking or aspiration—when food or liquid enters the lungs—by modifying food consistency. This diet bridges the gap between a pureed diet (Level 1) and an advanced or regular diet (Levels 3 and 4). A healthcare team, including a speech-language pathologist and a registered dietitian, will determine if this diet is appropriate for an individual's specific needs.

Key characteristics of a Level 2 diet:

• Moisture is essential: All foods must be soft, moist, and cohesive to help them form a single, easy-to-swallow mass, or bolus. Dry, tough, or crumbly foods are strictly avoided.
• Finely minced or ground texture: Food is finely chopped, ground, or mashed into small, manageable pieces, typically no larger than 1/4 inch.
• Minimal chewing effort: Foods should require minimal effort to chew and move around in the mouth.
• Increased variety from puree: Unlike a pureed diet, a Level 2 diet includes more varied textures, which can improve the overall dining experience for the individual.

Example Foods for a Level 2 Diet

A meal on a Level 2 diet might consist of foods from several different food groups, all prepared to meet the specific texture requirements. The examples below illustrate how a typical menu could be adapted.

Protein sources

• Moist ground meats: Ground beef, chicken, or turkey mixed with gravy or sauce.
• Flaked, moist fish: Fish fillets that are cooked until soft and flaky, served with a sauce.
• Egg salad or tuna salad: Made without large chunks of celery or onion and moistened with mayonnaise or dressing.
• Soft-cooked eggs: Scrambled or poached eggs, mashed and moistened with butter or sauce.
• Soft tofu: Cooked and mashed.

Fruits and vegetables

• Well-cooked and mashed vegetables: Potatoes, carrots, or squash that are boiled or baked and easily mashed with a fork.
• Soft, canned fruits: Peaches, pears, or applesauce without skins or seeds.
• Ripe bananas: Mashed or sliced.
• Diced, soft-cooked vegetables: Vegetables chopped into small, moist pieces.

Grains and starches

• Moist pancakes or French toast: Served with syrup or sauce.
• Well-cooked cereals: Oatmeal or cream of wheat with milk.
• Moistened dry cereals: Cereals like corn flakes soaked in milk.
• Well-cooked pasta: Pasta in sauce, like macaroni and cheese, without large chunks.

Dairy and other items

• Pudding and custard: Smooth, soft-textured options.
• Yogurt and cottage cheese: Smooth varieties.
• Thickened liquids: For individuals who also have difficulty with thin liquids, mildly thick beverages (IDDSI Level 2 for liquids) may be recommended by a speech therapist.

International Dysphagia Diet Standardisation Initiative (IDDSI)

The IDDSI framework provides a global standard for dysphagia diets and liquid thickness. It uses a numbering system from 0 (thin liquids) to 7 (regular foods). It is important to note that the National Dysphagia Diet (NDD) Level 2 corresponds to IDDSI Level 5, which is described as "Minced and Moist". This level features foods that are finely minced and mixed with a moist sauce or gravy to hold them together but remain easily separated with a fork. This international standard helps ensure consistency of care across different regions and healthcare providers.

Comparing Dysphagia Diet Levels

Feature	Level 1: Pureed (IDDSI Level 4)	Level 2: Mechanically Altered (IDDSI Level 5)	Level 3: Advanced (IDDSI Level 6)
Texture	Smooth, uniform, and pudding-like consistency.	Soft and moist, with finely minced or ground particles.	Soft and bite-sized; foods are soft, tender, and moist throughout.
Chewing	No chewing is required.	Requires minimal chewing.	Requires some chewing.
Moisture	High moisture content; holds its shape but is not sticky.	Extra moisture is added via sauces or gravies to ensure cohesion.	Foods are naturally moist or have added moisture.
Particle Size	No lumps or pieces.	Finely minced, generally less than 1/4 inch (or 4mm for IDDSI).	Soft, bite-sized pieces (15mm for adults).
Example Food	Pureed carrots	Mashed potatoes with gravy	Soft cooked pasta
Tool for Prep	Blender or food processor.	Food processor, fork, or chopper.	Knife and fork, though food is already tender.

How to prepare foods for a Level 2 Diet

Proper food preparation is crucial for a Level 2 diet to ensure safety and palatability. Here are some techniques to follow:

• Use a food processor: A food processor is ideal for creating the finely minced or ground texture required for many foods, such as meats and vegetables.
• Add moisture: Always incorporate extra moisture to prevent dryness and help foods form a cohesive bolus. This can include sauces, gravy, milk, butter, or broth.
• Cook thoroughly: Ensure all vegetables and meats are cooked until they are very tender and soft before mincing or mashing them.
• Mash with a fork: For softer items like potatoes, bananas, and soft-cooked eggs, a fork may be enough to achieve the desired texture.
• Soften bread products: Moisten soft breads or pancakes with sauce or syrup to make them easier to swallow.

Conclusion

What is an example of a Level 2 diet? An example of a Level 2 diet is a meal of moist ground beef with gravy, mashed potatoes, and well-cooked, finely diced carrots. This diet is a critical nutritional tool for managing dysphagia by providing a safe and palatable transition from pureed foods. Adhering to the specific texture and moisture requirements, such as those outlined by the IDDSI framework, is essential for a patient's safety. Always consult with a healthcare provider or speech-language pathologist to ensure the diet is appropriate for an individual's specific swallowing abilities and nutritional needs.
