The International Dysphagia Diet Standardisation Initiative (IDDSI) was founded to develop the international standardisation terminology to describe texture-modified foods and thickened liquids used by people with Dysphagia.
The IDDSI Committee found that a number of countries had developed their own range of Dysphagia standards using different labels, numbers and levels. People with Dysphagia may come across a confusing array of terminologies for any one thickness of drink such as Nectar, Syrup, Level 150, and Mildly Thick.
The IDDSI Committee has created a universal Dysphagia diet framework consisting of 8 levels for food and drink. Within this framework, liquids are now defined as - thin (Level 0), slightly thick (Level 1), mildly thick (Level 2), moderately thick (Level 3), and extremely thick (Level 4).
