The International Dysphagia Diet Standardisation Initiative (IDDSI) developed a global framework to provide standardized terminology for texture-modified foods and thickened liquids. This was designed to eliminate the confusion caused by varied and ambiguous descriptors previously used across healthcare settings. At the top of this framework is Level 7, a category with two distinct components: Regular (RG7) and Regular Easy to Chew (EC7). Both are assigned the color black in the IDDSI framework.
Regular (RG7): The Standard Diet
The Regular (RG7) diet is for individuals who do not have any identified chewing or swallowing problems. For this group, there are no restrictions on food size, shape, or texture. This includes hard, tough, chewy, fibrous, or crunchy foods, as the individual is considered fully capable of safely managing and chewing all everyday foods and drinks. For example, a person on a regular diet can safely eat raw vegetables, steak, nuts, and crispy snacks. Because there are no restrictions, there is no specific testing method for this sub-level beyond simply confirming the individual has a normal, healthy swallow function.
Easy to Chew (EC7): The Modified Normal Diet
The Easy to Chew (EC7) diet is a modified version of the Regular diet, intended for individuals who experience difficulty or pain when chewing hard or tough foods but do not have a clinically identified swallowing disorder (dysphagia) or an increased risk of choking. This might be due to age-related changes, dental issues, or recovery from an illness. The key characteristic is that while normal, everyday foods can be served, they must be soft and tender.
Characteristics of Easy to Chew (EC7) Foods
- Soft and Tender: Foods must be soft enough to be easily broken apart or separated with the side of a fork or spoon. A knife is not required for cutting.
- Easy to Mash: When pressed with a fork, the food should easily squash and not regain its shape when the pressure is released.
- Variable Particle Size: Unlike lower IDDSI levels, there is no specific restriction on the size of the food pieces. The individual is able to safely take appropriately sized bites.
- No Hard, Tough, or Chewy Bits: Foods with hard bits, tough skins, or chewy textures are to be avoided.
- Appropriate for Mixing: Mixed-consistency foods, such as soups with soft food pieces, may be included, unlike diets for those with higher choking risks.
Examples of Suitable Easy to Chew (EC7) Foods
- Soft Meats: Tender, slow-cooked meat that flakes easily, or meatloaf.
- Tender Vegetables: Softly boiled, steamed, or roasted vegetables like carrots, cauliflower, or sweet potato.
- Soft Fruits: Ripe bananas, peeled peaches, or canned fruit.
- Moistened Starches: Well-cooked pasta, soft rice, or moistened cereals.
- Fish: Flaked fish or tender fish cakes.
- Eggs: Scrambled or soft-boiled eggs.
Examples of Foods to Avoid on an Easy to Chew (EC7) Diet
- Hard Foods: Nuts, seeds, popcorn, or raw carrots.
- Tough Foods: Steak, tough meat, or fibrous pineapple.
- Chewy Foods: Chewy sweets, marshmallows, or dried fruit.
- Stringy Foods: Runner beans, celery, or rhubarb.
- Crumbly Foods: Dry biscuits or crackers.
- Foods with Skins/Bones: Chicken with skin, peas with skins, or bony fish.
The Role of the IDDSI Framework in Clinical Practice
Adopting the IDDSI framework helps improve patient safety by ensuring clear and consistent communication regarding diet modifications. Health professionals, including doctors, dietitians, and speech-language therapists, work together to prescribe the correct diet level based on a patient's individual chewing and swallowing abilities. The specific terminology and testing methods allow kitchen staff and caregivers to prepare and check food textures accurately. This reduces the risk of errors and potential adverse events, such as choking. The IDDSI website provides comprehensive resources and testing methods to aid in implementation, making it an invaluable tool for global healthcare. For more information, visit the IDDSI website.
Conclusion
Understanding what a level 7 diet texture entails is vital for ensuring appropriate care for individuals with varying chewing abilities. The distinction between the Regular (RG7) and Regular Easy to Chew (EC7) sub-levels provides a clear and safe pathway for managing diet consistency. While Regular is for those with no chewing or swallowing issues, Easy to Chew offers a modified option for individuals who struggle with harder textures due to factors like dental problems or fatigue. By following the IDDSI framework and its clear guidelines, caregivers and clinicians can promote comfortable, safe, and dignified eating experiences for all.
Comparison of IDDSI Levels 6 and 7
| Feature | IDDSI Level 6: Soft & Bite-Sized | IDDSI Level 7: Easy to Chew (EC7) | 
|---|---|---|
| Chewing Required | Minimal chewing needed. | Chewing is required, but without fatigue or pain from hard/tough foods. | 
| Food Particle Size | Standardized, controlled size (e.g., adult 1.5 cm pieces). | No restriction on food piece size. | 
| Texture | Soft, moist, and tender, with no separate thin liquid. | Soft and tender, may include dual consistencies. | 
| Testing Method | Fork pressure test (thumbnail blanches white) and particle size check. | Fork/spoon pressure test to ensure food mashes easily. | 
| Appropriate For | Individuals who can chew but have reduced bite force due to missing teeth or poorly-fitting dentures. | Individuals with good chewing ability who find hard foods difficult or tiring, often due to dental issues or general fatigue. | 
| Risk of Choking | Still requires monitoring, as controlled particle size is needed. | Not for those with an identified choking risk. |
