IDDSI Standard

Diagram showing different types of transitional foods based on texture and thickness. From thin to thick: thin, slightly thick, mildly thick, moderately thick, extremely thick, pureed, minced & moist, soft & bite-sized, regular. The categories are color-coded and labeled with their respective numerical codes.

The IDDSI framework consists of a continuum of the 8 levels (0 - 7). 

  • Drinks are measured from Levels 0 – 4.

  • Foods are measured from Levels 3 – 7.  

The IDDSI Framework provides a common terminology to describe food textures and drink thickness.

IDDSI Testing Methods are intended to confirm the flow or textural characteristics of a particular product at the time of testing.  Testing should be done on foods and drinks under the intended serving conditions (especially temperature).  The clinician has the responsibility to make recommendations for foods or drinks for a particular patient based on their comprehensive clinical assessment.
