The International Dysphagia Diet Standardisation Initiative (IDDSI) was founded in 2013 with the goal of developing new international standardised terminology and definitions to describe texture modified foods and thickened liquids used for individuals with dysphagia of all ages, in all care settings, and all cultures.
Three years of work by the International Dysphagia Diet Standardisation Committee culminated in the 2016 release and 2017 publication of the IDDSI Framework consisting of a continuum of 8 levels (0-7). Levels are identified by numbers, text labels and colour codes.
