IDDSI is the International Dysphagia Diet Standardisation Initiative.
Why is this food texture needed?
It can be recommended for people who may have difficulties biting off pieces of food, chewing and swallowing but are able to chew bite-sized pieces down into little pieces that are safe to swallow. A moderate amount of chewing is required. The pieces are ‘bite-sized’ to reduce choking risk.
Non-urgent advice: What is soft and bite sized food?
- It is soft, tender, and moist but with no thin liquid leaking/dripping from the food.
- It requires chewing. Ability to ‘bite off’ a piece of food is not required.
- It can be mashed or broken down with pressure from a fork. A knife is not required to cut this food.
- Bite sized pieces, no larger than 1.5cm X 1.5cm (1/2 inch) each way.
- Usually requires a smooth thick sauce.
Urgent advice: Do not
- Do not use foods that are hard, tough, chewy, fibrous, have stringy textures, pips/seeds or bones.
- No juicy food where juice separates off in the mouth.
- No mixed (thick-thin) textures for example cereal in milk, mince in thin gravy, dried fruit in sponge.
- No husks, skins or outer shells for example on peas, grapes.
Food Examples
All Level 6 foods must be chopped into bite sized pieces (1.5cm x 1.5 cm (½ inch)) before eating.
Meat
- Cooked until tender and chopped so pieces are no longer than 1.5cmx1.5cm lump size.
- If you cannot serve soft and tender, serve as minced and moist
Fish
- Cooked soft enough to break and serve in pieces no larger than 1.5cmx1.5cm
Fruit
- soft and chopped to pieces no larger than 1.5cmx1.5cm pieces (drain any excess liquid).
- Do not use the fibrous parts of fruit (for example, the core or zest such as the white parts of an orange).
- Be extra careful if you are eating fruit with a high water content, where the juice separates from the solid in the mouth during chewing (for instance, fruits like watermelon or other melons).
Vegetables
- Vegetables steamed or boiled with final cooked size no larger than 1.5cmx1.5cm.
- Stir fried vegetables are too firm and are not suitable for this texture.
Cereal
- Served with pieces no bigger than 1.5cmx1.5cm, with their texture fully softened.
- Drain excess liquid before serving.
Dessert
- No ice-cream or jelly if a person requires thickened fluids (because these can change to thin fluid in the mouth)
Rice
- Requires a sauce to moisten it and hold it together.
- Rice should not be sticky or gluey and should not separate into individual grains when cooked and served.
- May require a thick, smooth, non-pouring sauce to moisten and hold the rice together
