International Dysphagia Diet Standardisation Initiative (IDDSI) Framework

Summary

The International Dysphagia Diet Standardisation Initiative (IDDSI) is a global standard with terminology and definitions to describe the texture-modified foods and the thickened fluids sometimes used for individuals with dysphagia. IDDSI applies to all ages, in all care settings, and for all cultures. The IDDSI framework consists of a continuum of 8 levels (0-7). Levels are identified by text labels, numbers, and colour codes to improve safety and identification. Each level has standardised descriptors and simple testing methods so that people can consistently produce the required thickness of drinks and/or texture of foods.
