A Level 5 diet, or Minced and Moist, is part of the IDDSI framework designed for people with dysphagia, or swallowing difficulties. This food texture is soft, moist, and cohesive, requiring minimal chewing and no biting, making it easier and safer to swallow. Food on this diet must hold its shape but be easy to mash with a fork, and lumps must be no larger than 4mm for adults. By understanding the principles and allowed food types, individuals and caregivers can prepare a varied and enjoyable diet.
Key Principles of a Level 5 Diet
For a meal to be considered safe for a Level 5 diet, it must adhere to several key characteristics.
- Soft and Moist: The food must be thoroughly moistened with thick, non-pouring sauces, gravy, or other liquids to prevent dryness. No thin liquid should separate from the solid food.
- Small Lumps: For adults, any lumps present should be no larger than 4mm, roughly the size of the gap between the tines of a standard dinner fork.
- Cohesive and Non-Sticky: The food should form a cohesive bolus, or ball, in the mouth and not be sticky, which could cause it to adhere to the teeth, roof of the mouth, or throat.
- Minimal Chewing: Minimal chewing is required, as the food should break apart easily with pressure from the tongue. Biting is not required.
Allowed Foods on a Level 5 Diet
Protein Sources
- Meat, Poultry, and Fish: Finely minced or chopped, tender meats, and poultry without skin, gristle, or bones are suitable when served in a thick, smooth, non-pouring sauce or gravy. Examples include cottage pie, mashed fish, and mince with gravy.
- Eggs: Scrambled or mashed poached eggs are excellent choices.
- Legumes: Mashed beans and soft, mashed lentils (dahl) are suitable, ensuring they are well-cooked and free of tough skins.
- Tofu: Small pieces of very soft tofu are acceptable.
Fruits and Vegetables
- Vegetables: Cooked, soft vegetables that have been finely minced and mashed, with all skins and stalks removed, are permitted. Examples include mashed potatoes, carrots, parsnips, and cauliflower. Excess liquid should be drained.
- Fruits: Mashed or stewed fruits like bananas, apples, and pears are allowed, provided skins and pips are removed and excess fluid is drained.
Grains and Starches
- Cereals: Porridge or soaked breakfast cereals, such as Weetabix, are safe as long as all fluid is fully absorbed and there is no excess milk.
- Bread: Regular dry bread is a choking risk. Pre-gelled, soaked bread that is moist and gelled throughout is a safe alternative.
- Rice and Pasta: These can be included when mashed into a thick, smooth, non-pouring sauce or gravy to ensure cohesiveness. Examples include creamy risotto or mashed ravioli in a thick sauce.
Dairy and Desserts
- Dairy Products: Smooth, creamy yogurt, custard, and milk puddings are acceptable. Finely grated cheese can be incorporated into dishes but must be melted completely.
- Desserts: Mousse, crème caramel, and mashed sponge puddings with custard or cream are safe choices.
Preparing Level 5 Minced and Moist Meals
Home preparation of a Level 5 diet is achievable with the right techniques and equipment.
- Tools: Use a potato masher for softer items, a fork for mashing smaller portions, and a food processor or blender for mincing meats and vegetables. A whisk can help incorporate thickeners or dry milk powder.
- Moisture is Key: When mashing fruits or vegetables, add a small amount of liquid like milk, juice, or cream, and then drain any excess. When mincing meat, blend with gravy, stock, or cream to create a moist, smooth texture.
- Testing: Always perform the IDDSI Fork Drip and Spoon Tilt tests on prepared food to ensure it meets the requirements before serving.
Comparison: Level 5 Minced & Moist vs. Other Textures
| Feature | Level 4 Pureed | Level 5 Minced & Moist | Level 6 Soft & Bite-Sized |
|---|---|---|---|
| Chewing | Not required. | Minimal chewing needed; food mashes with the tongue. | Chewing is required before swallowing. |
| Texture | Completely smooth, with no lumps or particles. | Soft, moist, and cohesive with small, soft lumps (4mm for adults). | Soft, tender, and moist, with bite-sized pieces (15mm for adults). |
| Biting | Not required. | Not required. | Biting is not required. |
| Liquid Separation | Must not separate into thin liquid. | No separate thin liquid. | No separate thin liquid. |
| Example | Smooth custard, vegetable puree. | Mashed potatoes with gravy, minced meat with sauce. | Soft-cooked pasta, finely diced casserole. |
Foods to Avoid on a Level 5 Diet
For safety, certain food characteristics must be avoided:
- Hard, dry, or crumbly foods (e.g., toast, biscuits).
- Tough or fibrous foods (e.g., steak, pineapple).
- Chewy or crispy foods (e.g., nuts, bacon).
- Food with skins, husks, pips, seeds, bones, or gristle (e.g., peas, grapes).
- Sticky foods (e.g., nut butter, sticky rice).
- Foods with mixed textures, such as chunky soups.
- Dry rice or individual grains that separate.
Conclusion
Navigating what foods are allowed on a Level 5 diet is essential for both the safety and nutritional well-being of individuals with dysphagia. By following the IDDSI guidelines, including the specific texture, lump size, and moisture requirements, it is possible to create safe, varied, and appealing meals that minimize the risk of choking and make mealtimes a positive experience. Consult with a healthcare professional, such as a Speech and Language Therapist or Dietitian, for personalized recommendations.
