Understanding the Level 6 (Soft and Bite-Sized) Diet
A Level 6 diet, as defined by IDDSI, is a modified texture diet designed for people with mild dysphagia or difficulty chewing. The foods are soft, tender, and moist throughout, requiring some chewing before swallowing. Food pieces are typically no larger than 1.5 cm for adults to minimize the risk of choking. This includes well-cooked, minced meat, soft vegetables, and fruits, all served with a smooth sauce or gravy to add moisture. Foods that are crunchy, dry, crumbly, or have skins and seeds are strictly avoided.
While the diet ensures safety, the restrictive nature of food textures can present a nutritional challenge. Patients may have a poor appetite, feel full faster, or simply not consume enough volume of food to meet their daily energy and protein requirements. This can lead to unintended weight loss and malnutrition, making supplementation a critical consideration.
The Role of Food Enrichment on a Level 6 Diet
Before turning to supplements, food enrichment is often the first strategy recommended by dietitians to increase the calorie and protein density of meals. This involves adding extra nutrients to regular food items. It is a highly effective way to bolster nutritional intake without changing the overall meal volume significantly. For example, stirring dried milk powder into milk-based dishes can increase the protein content, while adding butter or oil can boost calories.
Practical ways to enrich your meals
- Add extra dairy: Stir grated cheese into mashed potatoes, pasta, and soups. Use full-fat milk, cream, or yogurt in puddings and smoothies.
- Use healthy fats: Be generous with butter, margarine, or oil when preparing vegetables or sauces.
- Fortify beverages: Make high-calorie shakes or smoothies using ice cream, full-fat milk, and pureed fruit.
- Include protein-rich additions: Blend smooth nut butters into drinks or add them to oatmeal. Add cottage cheese or ricotta to smoothies or sauces.
When Oral Nutritional Supplements (ONS) Become Necessary
Despite best efforts with food enrichment, some individuals on a Level 6 diet may still struggle to meet their nutritional targets. This is where oral nutritional supplements (ONS) may be recommended by a healthcare professional, such as a dietitian or a GP. ONS are specialist, high-calorie, and high-protein products available as drinks or puddings. They are intended to be consumed in addition to regular meals, not as a replacement. A dietitian will monitor weight and overall intake to determine if and when ONS are needed and what type is most suitable.
Comparing Food Enrichment and Oral Nutritional Supplements
| Feature | Food Enrichment | Oral Nutritional Supplements (ONS) |
|---|---|---|
| Mechanism | Adding extra calories and protein to existing food and drinks. | Consuming specialized, high-density nutrition products. |
| Application | Blending fats, powdered milk, or cheeses into homemade meals. | Drinking prescribed nutrition shakes or eating special puddings. |
| Benefit | Enhances the nutritional value of regular food, potentially improving appetite. | Provides a guaranteed, measured dose of calories and protein. |
| Supervision | Often guided by a dietitian, but can be self-implemented with guidance. | Prescribed and monitored by a healthcare professional. |
| Suitability | Ideal for those who can consume sufficient food volume but need higher calorie/protein density. | Best for individuals struggling with appetite, weight loss, or inability to meet needs with food alone. |
The Importance of Professional Guidance
It is crucial to work with a healthcare team, including a dietitian and speech and language therapist, when following a Level 6 diet. These professionals ensure the diet is safe, addresses swallowing issues, and meets all nutritional requirements. A dietitian can conduct a nutritional assessment to identify any gaps in intake and help create a customized plan, which may or may not include supplements. They can also help with meal planning, portion sizes, and strategies to increase overall food intake. Individuals who experience continued weight loss should inform their GP or dietitian immediately.
Conclusion
Supplements are not automatically required for a Level 6 diet, but they can become a necessary tool to prevent malnutrition and weight loss. The decision depends heavily on the individual's ability to maintain adequate nutritional intake through modified foods. A proactive approach starts with maximizing food enrichment techniques and closely monitoring weight. When these efforts prove insufficient, oral nutritional supplements can provide a vital safety net. Any decision to start supplementation should always be made in consultation with a healthcare professional to ensure it is appropriate and properly managed.
