Understanding the Level 6 Soft and Bite-sized Diet
The International Dysphagia Diet Standardisation Initiative (IDDSI) created a global framework to categorize food and fluid textures for people with swallowing difficulties (dysphagia). The Level 6, or 'Soft and Bite-sized' diet, is for those who can chew but may have trouble biting or safely managing more complex food textures. The primary characteristics of this diet are foods that are soft, tender, and moist throughout. All food pieces must be cut to a specific size—no larger than 1.5cm by 1.5cm for adults—to minimize choking risk. Foods should also be easily mashed or broken down with the pressure of a fork.
Categories of Unsafe Foods for a Level 6 Diet
To ensure safety on a Level 6 diet, certain food characteristics must be strictly avoided. These textures are challenging to chew and manipulate in the mouth and can increase the risk of aspiration or choking.
Hard, Crunchy, and Crumbly Textures
Foods that are hard, crunchy, or crumbly can break into small, sharp fragments that are difficult to gather and swallow safely. Raw vegetables like carrots, cauliflower, and broccoli are too firm, as are crispy items such as cornflakes, crisps, popcorn, and crackers. Nuts and seeds are also hazardous. Dry, crumbly baked goods like certain cakes and biscuits without added moisture should also be avoided.
Chewy and Sticky Foods
Sticky and chewy foods can cling to the teeth or the roof of the mouth, making them very difficult to clear during the swallowing process. Examples of high-risk items include tough or fibrous meats, dried fruits (raisins, figs), chewy candies (marshmallows, gummy bears), and some nut butters. Even sticky mashed potato can be a problem.
Stringy and Fibrous Items
Fibrous or stringy textures can clump together and get stuck, leading to an increased risk of choking. Foods like celery, pineapple, runner beans, and certain types of bacon are examples of fibrous items that are not suitable for this diet. Tender meat should be cut against the grain to reduce stringiness.
Foods with Skins, Seeds, or Husks
Skins and seeds, even small ones, can be difficult to manage and swallow safely. This includes the skins on fruits (grapes, peaches), vegetables (peas, baked beans), and other items with husks or pips. When preparing fruits for a Level 6 diet, skins should be removed, and the fruit should be soft and chopped.
Mixed Consistency Foods
Foods with both a thin liquid and a solid component can be particularly dangerous. The thin liquid can be swallowed before the solid part is ready, increasing the risk of aspiration. Examples to avoid include watery soup with lumps, mince in a thin gravy, and breakfast cereal in milk where the cereal does not soften sufficiently. Any sauces or gravies should be thick enough to bind to the food.
Tough Meats and Foods with Bones
Any meat that is not cooked until tender and moist should be avoided. This includes tough cuts of beef, gristly meat, and meat with skins or bones. Similarly, fish must be checked carefully to ensure all bones are removed. Instead, opt for slow-cooked, tender meats or finely minced preparations.
Risky Shapes and Sizes
Some foods, due to their size and shape, are more likely to cause choking. Small, round foods like whole grapes, cherries, and olives should be avoided or cut into smaller pieces. Long, cylindrical foods like sausages must also be cut appropriately.
Foods That Melt to Thin Liquid
If thickened fluids are also prescribed, foods that melt into a thin liquid in the mouth are unsafe. This includes ice cream, gelatin (jelly), and frozen yogurt. The change in consistency can pose a significant aspiration risk.
Comparison: Safe vs. Unsafe Foods on a Level 6 Diet
| Category | Unsafe Food Example | Safe Food Alternative/Modification |
|---|---|---|
| Meat | Tough steak, jerky, sausages with skins | Slow-cooked casserole meat cut into 1.5cm pieces; skinless sausages cut and served with thick gravy |
| Fruits | Whole grapes, raw apple, pineapple, dried fruit | Soft, ripe banana; chopped canned peaches (drained); stewed apple (peeled) |
| Vegetables | Raw carrots, celery, corn on the cob | Soft-boiled or steamed carrots (cut small); cooked cauliflower and broccoli florets |
| Grains | Dry toast, crackers, hard cereal | Porridge; Weetabix soaked well in milk; pasta cooked until very soft |
| Snacks | Nuts, crisps, popcorn, hard candies | Smooth yogurt; custard; soft sponge cake with cream |
| Desserts | Pie with hard pastry, crumble topping, dry cake | Plain sponge cake with custard; soft milk puddings; cheesecake topping |
Essential Tips for Food Preparation and Modification
Following a Level 6 diet involves careful food preparation to ensure safety and proper nutritional intake. Here are some key tips:
- Cut to Size: All solid food pieces must be cut into bite-sized pieces, no larger than 1.5cm by 1.5cm for adults, before serving. This applies to meat, vegetables, and fruit.
- Ensure Moisture: Foods must be kept moist with thick sauces, gravy, or custard to prevent them from becoming dry and crumbly. For instance, serve tender meat in a thick sauce.
- Use Proper Cooking Methods: Boiling, steaming, and slow-cooking are preferred methods to ensure foods are tender. Avoid frying or stir-frying, as this can make food too firm.
- Bind Ingredients: In dishes like rice and pasta, use a thick, smooth sauce to bind the food together, preventing it from separating into individual, hard-to-manage pieces.
- Modify Cereals: For breakfast, choose cereals that soften completely when soaked in milk, like porridge or Weetabix. Drain off any excess thin liquid before eating.
- Handle Fruits and Vegetables with Care: Peel all skins from fruits and vegetables, and remove all pips, seeds, and fibrous parts. Cook vegetables until they are tender and easily mashable with a fork.
- Avoid Mixed Textures: Be mindful of foods that naturally have mixed consistencies. If a soup contains lumps, strain it or ensure the liquid is thick and fully binds with the solids.
Conclusion: The Importance of Professional Guidance
While this guide provides a comprehensive overview of what foods are unsafe for level 6 diet, it should not replace the advice of a healthcare professional. A speech and language therapist or a registered dietitian can provide a personalized assessment and create a safe and nutritionally adequate eating plan. Adhering to the recommended food texture and consistency is vital for reducing the risk of choking and aspiration pneumonia, ensuring both safety and quality of life for those with dysphagia.

Safety Procedures for Eating on a Level 6 Diet
In addition to selecting and preparing the right foods, following safe eating procedures is paramount:
- Sit Upright: Always ensure an upright sitting position while eating and for at least 30 minutes afterward to aid safe swallowing.
- Take Small Bites: Encourage small, manageable bites and sips. Avoid taking large mouthfuls.
- Concentrate on Eating: Minimize distractions and avoid talking while chewing and swallowing.
- Check the Mouth: After eating, check the cheeks and mouth for any leftover food residue.
- Supervise Meals: If necessary, a caregiver or family member should supervise mealtimes to ensure the process is safe.
