IDDSI Framework Levels

The IDDSI framework consists of 8 levels (0-7) describing food textures and liquid thickness. Levels 0-4 apply to drinks, while levels 3-7 apply to foods.

DDrink Levels (0-4)

Level 0

Thin

Flows like water. No modification needed for typical thin beverages.

Level 1

Slightly Thick

Thicker than water. Requires slightly more effort to drink than thin liquids.

Level 2

Mildly Thick

Flows off a spoon quickly. Can be drunk from a cup with some effort.

Level 3

Moderately Thick / Liquidised

Can be drunk from a cup. Will drip in dollops through fork tines. Smooth with no lumps for liquidised foods.

Level 4

Extremely Thick / Pureed

Usually eaten with a spoon. Does not require chewing. Falls off spoon in a single spoonful when tilted.

FFood Levels (3-7)

Level 3

Moderately Thick / Liquidised

Can be drunk from a cup. Will drip in dollops through fork tines. Smooth with no lumps for liquidised foods.

Level 4

Extremely Thick / Pureed

Usually eaten with a spoon. Does not require chewing. Falls off spoon in a single spoonful when tilted.

Level 5

Minced & Moist

Soft, moist pieces with no separate thin liquid. Pieces small enough that minimal chewing required.

Level 6

Soft & Bite-Sized

Soft, tender, moist food cut into bite-sized pieces. Requires chewing before swallowing.

Level 7

Regular / Easy to Chew

Normal everyday foods of soft-tender textures or regular textures depending on patient needs. Full range of textures.
