Understanding the IDDSI Framework and Easy-to-Chew Foods
The International Dysphagia Diet Standardisation Initiative (IDDSI) created a global framework to classify textured food and liquids for individuals with swallowing difficulties (dysphagia). The framework uses eight levels, numbered 0 to 7, to ensure consistency and safety for patients worldwide. A Level 7 diet encompasses regular foods, with a specific sub-category known as "Regular Easy to Chew". This sub-category focuses on soft and tender foods that are easy to break down, accommodating people with compromised chewing ability.
Who Needs a Level 7 Easy to Chew Diet?
This diet is typically recommended for individuals who can chew and swallow safely but find harder textures difficult or uncomfortable to manage. Common reasons include:
- Dental Issues: Lack of teeth, poorly fitting dentures, or pain from dental problems can make chewing tough foods challenging.
- Recovery from Illness: Individuals recovering from an illness or injury may have weaker chewing muscles and find softer foods easier to manage.
- Age-related Fatigue: As people age, muscle strength, including those used for chewing, can diminish, leading to tiring during meals.
- Rehabilitation: It can also be used as a transitional step for patients working towards advanced chewing skills.
It is crucial to note that this diet is not suitable for people with a high risk of choking or significant swallowing problems, as it does not impose size restrictions on food pieces.
Key Characteristics of a Level 7 Easy to Chew Diet
To ensure food safety and comfort on this diet, specific guidelines must be followed. These characteristics relate to the food's texture and are easily tested.
- Soft and Tender Texture: All foods must be naturally soft or cooked until tender.
- Easily Separated: Foods should break apart easily with the side of a fork or spoon. The 'Fork Pressure Test' can confirm this: press down with a fork until the thumbnail blanches white, then lift the fork to see if the food is completely squashed and holds its shape.
- Moist Consistency: Food should be served with adequate moisture from sauces, gravies, or cooking liquids to aid swallowing and prevent crumbling.
- No Size Restrictions: Unlike lower IDDSI levels, there are no specific particle size limits. Individuals are expected to bite and chew appropriately.
- Foods to Avoid: Hard, tough, chewy, stringy, fibrous, or crunchy foods should be omitted.
Examples of Suitable and Unsuitable Foods
Suitable Level 7 Easy to Chew Foods
- Proteins: Tender, cooked meats (e.g., stews, casseroles), flaked fish, eggs (scrambled, poached), soft tofu, and cooked beans.
- Fruits: Soft, fresh, or canned fruits like ripe bananas, peaches, pears, and mangoes. Remove skins and seeds.
- Vegetables: Softly boiled or steamed vegetables like carrots, cauliflower, potatoes (without skin), and sweet potato.
- Grains: Soft cereals soaked in milk, well-cooked pasta, rice, and moist, soft bread without tough crusts.
- Dairy: Yogurt, smooth cottage cheese, ricotta cheese, and creamy puddings.
Unsuitable Foods to Avoid
- Proteins: Tough cuts of meat, crispy bacon, chicken with skin, and any meat with bones or gristle.
- Fruits/Vegetables: Raw vegetables (e.g., carrots, celery), crunchy apples, pineapple, corn kernels, and fruits with seeds or tough skins.
- Grains: Hard bread crusts, crunchy crackers, dry cakes, popcorn, and flaky pastries.
- Sticky/Chewy Foods: Marshmallows, dried fruits, chewy sweets, and some types of cheese.
- Crunchy/Crispy Foods: Nuts, crisps, crackling, and crunchy cereals.
Comparison of IDDSI Level 7 vs. Other Diets
| Feature | Level 7 Easy to Chew (EC7) | Level 6 Soft & Bite-Sized (SB6) | Level 5 Minced & Moist (MM5) |
|---|---|---|---|
| Food Texture | Regular, soft, tender foods. | Soft, moist, and tender. | Moist, cohesive, and easily mashed with a fork. |
| Particle Size | No specific size restriction. Patient controls bite size. | Limited to 1.5cm x 1.5cm. No lumps. | Limited to 4mm for adults (or 2mm for children). |
| Chewing Ability | Requires strong enough chewing to break down soft/tender food without tiring easily. | Minimal chewing needed. | Minimal chewing needed. |
| Choking Risk | Not for individuals with an identified choking risk. | Lower choking risk due to size limitation. | Significantly reduced choking risk due to texture. |
| Moisture | Foods should be soft and moist. | Moist and cohesive, no separate thin liquids. | Moist and clumped, no separate thin liquids. |
| Who It's For | Patients with mild chewing difficulties (e.g., dental issues, fatigue). | Patients with mild-to-moderate oral phase dysphagia. | Patients with moderate-to-severe dysphagia or reduced chewing ability. |
Preparing Easy to Chew Meals
Meal preparation for a level 7 easy to chew diet focuses on cooking methods that tenderize food and incorporating moisture. Using a pressure cooker or slow cooker can help soften meats, while boiling, steaming, or baking can make vegetables tender. Adding sauces, gravy, yogurt, or melted cheese can enhance moisture and flavor.
Recipe Idea: Tender Chicken Curry
- Prepare: Use skinless, boneless chicken thighs for maximum tenderness. Cube the chicken and brown it lightly in a pot.
- Cook: Add a base of soft, chopped vegetables like boiled carrots and butternut squash. Pour in a mild curry sauce or make one with coconut milk, spices, and broth. Ensure all vegetables are cooked until very soft.
- Simmer: Simmer the curry slowly to allow the chicken to become tender enough to break apart easily with a fork.
- Serve: Serve with well-cooked rice or soft noodles. Check the consistency with the fork test before serving. This meal is naturally moist and flavorful.
Conclusion
A level 7 easy to chew diet, a sub-category of the IDDSI framework's Regular diet, is an essential tool for managing mild chewing difficulties. By focusing on soft, tender, and moist foods while avoiding tough, chewy, or hard textures, individuals can maintain their nutritional intake with greater safety and comfort. Always ensure that you consult with a healthcare professional, such as a Speech and Language Therapist or Dietitian, before beginning any texture-modified diet, especially if there is a risk of choking. The IDDSI framework provides clear, testable guidelines for preparation, making it a reliable standard for caregivers and patients alike.
