According to the National Foundation of Swallowing Disorders, over 590 million people worldwide live with dysphagia. For those diagnosed, understanding what does level 2 dysphagia mean is crucial for safe eating, as it involves significant diet modifications to prevent choking and aspiration.

Quick Summary

This article explains the meaning of level 2 dysphagia by detailing the diet requirements, food preparation, and potential health risks. It compares the older National Dysphagia Diet (NDD) with the newer International Dysphagia Diet Standardisation Initiative (IDDSI), providing clear guidance for managing this condition.

Key Points

NDD vs. IDDSI: Be aware that "Level 2" can mean different things under the older National Dysphagia Diet (Mechanically Altered Solids) versus the newer, global IDDSI framework (Mildly Thick Liquids).
Mechanically Altered/Minced & Moist Diet: The goal for solids is a soft, moist, cohesive texture with small, uniform particles to reduce chewing effort and minimize risk.
Proper Preparation: Foods should be minced, ground, or mashed and combined with gravy, sauce, or other moisture-adding liquids to prevent dryness.
Fluid Consistency: If following IDDSI, mildly thick liquids (Level 2) are used for people who struggle with thin liquids, and the thickness should be verified with the IDDSI flow test.
Safe Eating Techniques: Always eat in an upright position, take small bites, and swallow carefully. Speech-language pathologists can provide specific swallowing exercises.
Avoid Risky Foods: Stay away from dry, hard, tough, sticky, or fibrous foods, which pose a significant choking hazard for individuals with level 2 dysphagia.
Address Nutrition & Hydration: Work with a dietitian to ensure adequate intake of calories, protein, and fluids, which can be challenging on a modified diet.

Deciphering Dysphagia: Understanding the Different Frameworks

When a healthcare professional, such as a Speech-Language Pathologist (SLP), diagnoses dysphagia, they determine the appropriate diet texture based on swallowing ability. The term "Level 2 dysphagia" can refer to different things depending on which dietary framework is used: the older National Dysphagia Diet (NDD) or the newer International Dysphagia Diet Standardisation Initiative (IDDSI).

The National Dysphagia Diet (NDD) Level 2: Mechanically Altered

The NDD was the primary framework in the U.S. until the adoption of the more standardized IDDSI system. Under the NDD, a Level 2 diet is known as "Mechanically Altered". This involves modifying regular foods to make them soft, moist, and easy to chew.

Food Texture: Foods are ground, chopped, or mashed into small pieces, typically no larger than 1/4 inch.
Key Characteristics: The food is moist and cohesive, meaning it sticks together well and doesn't separate into a thin liquid and a solid portion.
Chewing Ability: This diet is for individuals who have some chewing ability but struggle with hard, tough, or crunchy foods.

The International Dysphagia Diet Standardisation Initiative (IDDSI) and Level 2

The IDDSI is the current global standard, providing a more detailed and consistent framework. In the IDDSI system, a Level 2 designation applies specifically to liquids, while the solid food equivalent for the NDD Level 2 is IDDSI Level 5. This is a crucial distinction that healthcare providers communicate to ensure patient safety.

IDDSI Level 2: Mildly Thick Liquids
- Consistency: Mildly thick drinks flow slower than thin liquids (Level 0) and slightly thick liquids (Level 1) but can still be consumed from a cup or with a straw.
- Purpose: These liquids are easier to control in the mouth for individuals who have difficulty managing thinner fluids safely.
- Testing: The IDDSI flow test, using a 10 mL syringe, is the standard method for checking the thickness.
IDDSI Level 5: Minced and Moist Solids
- Consistency: This level corresponds to the NDD's mechanically altered diet, with foods finely minced or mashed and always combined with a moist sauce or gravy.
- Particle Size: Food particles must be small, typically no larger than 4mm for adults, and the texture must be soft and easy to mash with a fork.

Foods for a Mechanically Altered Diet (NDD Level 2 / IDDSI Level 5)

Navigating a dysphagia diet requires careful meal planning and preparation to avoid unsafe food textures. Here is a list of recommended and prohibited foods for a Mechanically Altered diet.

Foods to Enjoy

Grains: Moist, soft pancakes or bread with syrup; cooked cereals like oatmeal; moistened dry cereals with little texture.
Meats and Protein: Moistened ground or finely chopped meat, poultry, or fish with gravy; tuna or egg salad without large chunks; soft-cooked eggs.
Vegetables: Well-cooked, soft vegetables that are diced or mashed and served with sauce.
Fruits: Canned, drained fruits without seeds or skin; ripe banana; fruit pies with only a soft bottom crust.
Dairy: Pudding, custard, yogurt with no chunky fruit, cottage cheese, and soft cheeses.
Other: Soups with small, soft pieces of meat and vegetables (less than 1/2 inch); sauces, gravies, and dressings.

Foods to Avoid

Grains: Dry, crusty breads; tough crackers; rice; cereals with seeds or dried fruit.
Meats and Protein: Tough, dry meats; sausages, hot dogs, or bacon; cheese cubes or slices.
Vegetables: Raw or undercooked vegetables; corn; peas; fibrous vegetables like broccoli and asparagus.
Fruits: Raw, fibrous fruits; pineapple; fruits with skins or seeds; coconut; dried fruits.
Other: Sticky foods like peanut butter; nuts; seeds; tough or chewy candies.

Comparison of NDD Level 2 and IDDSI Level 5 Standards


Aspect	NDD Level 2 (Mechanically Altered)	IDDSI Level 5 (Minced and Moist)
Terminology	Older, U.S.-based terminology. Sometimes called "mechanical soft."	Newer, internationally standardized term. More specific and descriptive.
Food Particle Size	Food pieces generally no larger than 1/4 inch.	Adult size: particles up to 4mm wide and 15mm long. Pediatric size: 2mm particles.
Moisture Requirement	Requires added moisture (gravy, sauce) to keep food cohesive.	Explicitly requires food to be soft, moist, and cohesive throughout.
Testing Method	No standardized bedside testing method for texture consistency.	Uses a fork pressure test: food should squash easily and leave clear fork marks.
Mixed Consistencies	Often discouraged due to increased aspiration risk.	Strongly discouraged, as a mix of thin liquid and solids is unsafe.

Important Considerations for Managing Level 2 Dysphagia

Living with dysphagia requires more than just dietary changes. Following proper eating techniques and managing your environment can significantly reduce risks.

Swallowing Techniques: Your SLP will teach you specific techniques, such as the chin-tuck position, to facilitate a safer swallow.
Positioning: Always sit fully upright when eating and drinking. Remain in an upright position for at least 30 minutes after your meal to aid digestion and prevent reflux.
Oral Hygiene: Good oral hygiene is vital to prevent aspiration pneumonia. Poor swallowing can leave food particles in the mouth, which can lead to bacterial growth.
Hydration: Pay close attention to hydration levels. Thicken liquids according to the level prescribed by your healthcare provider. Thickened water, juice, or milkshakes can help meet fluid needs.
Caregiver Education: If you are a caregiver, it is important to understand the recommended diet and techniques. Attending medical appointments and helping with exercises can improve outcomes.
Watch for Red Flags: Be alert for signs of swallowing difficulty, such as coughing, choking, or a gurgly voice after eating. Report any new or worsening symptoms to a healthcare provider.

Conclusion: Navigating Your Dysphagia Journey

Understanding what does level 2 dysphagia mean is a vital step toward managing this condition safely and effectively. Whether following the NDD or IDDSI guidelines, the focus is on creating a soft, moist, and cohesive food texture to minimize the risk of choking and aspiration. Regular consultation with a healthcare team, including an SLP and a dietitian, is essential to tailor a plan that meets individual needs. By adhering to dietary modifications, practicing safe swallowing techniques, and managing hydration, individuals can maintain proper nutrition and a higher quality of life.

Frequently Asked Questions

The specific textures for each level differ between the NDD and IDDSI systems. Under the NDD, Level 2 is 'Mechanically Altered' (minced/moist), while Level 3 is 'Advanced' (soft, bite-sized). The IDDSI system uses Level 5 (Minced and Moist) for the equivalent of NDD Level 2 solids, and Level 6 (Soft and Bite-Sized) for solids corresponding to NDD Level 3.

For NDD Level 2 (IDDSI Level 5), you can eat foods that are moist, soft, and finely minced or mashed. Examples include moistened ground meat, soft-cooked vegetables, soft scrambled eggs, and well-soaked cereals. Foods must not be hard, tough, or dry.

To prepare mechanically altered foods, you must mince, chop, or mash items into small pieces (about 1/4 inch or smaller). Always add a sauce, gravy, or other liquid to ensure the food is moist and cohesive, preventing it from becoming dry or crumbly.

No, the IDDSI and NDD use different numbering systems, which is a major source of confusion. IDDSI Level 2 refers to 'Mildly Thick' liquids, while the NDD Level 2 refers to 'Mechanically Altered' solids. The IDDSI equivalent for NDD Level 2 solids is Level 5 (Minced and Moist).

Eating foods that are too hard, dry, or challenging to chew can lead to choking or aspiration. Aspiration occurs when food or liquid enters the airway instead of the esophagus, which can cause aspiration pneumonia, a serious lung infection.

Yes, IDDSI Level 2 (Mildly Thick) liquids are generally safe to consume with a straw. They flow at a slower rate than thinner liquids, making them easier to control and swallow safely for many individuals with dysphagia.

Common symptoms include coughing, gagging, or choking during or after eating; the sensation of food getting stuck in the throat or chest; pain when swallowing; or a gurgly, hoarse voice. If you experience these symptoms, consult a healthcare professional.
