International Dysphagia Diet Standardisation Initiative (IDDSI)

The Academy of Nutrition and Dietetics (AND), the Association of Nutrition & Foodservice Professionals (ANFP), and the American Speech-Language-Hearing Association (ASHA) support ongoing interprofessional collaborative practice to implement the International Dysphagia Diet Standardisation Initiative (IDDSI) since its official launch in May 2019 in the United States. IDDSI is an international collaboration of professionals who developed a standardized framework for labeling texture-modified foods and thickened liquids. 

Recognizing that total IDDSI implementation will take time and effort, AND, ANFP, and ASHA are committed to supporting its members during their transition. The United States IDDSI Reference Group (USIRG) was formed in November 2020 with the goal of facilitating and supporting implementation of IDDSI in the United States and Territories over the following 1–2 years. Representatives of AND, ANFP, and ASHA engage with the USIRG in ongoing implementation efforts across the country.

Note: The National Dysphagia Diet (NDD) was part of the full Nutrition Care Manual (NCM)® established by the Academy of Nutrition and Dietetics (AND). The AND announced that beginning in October 2021, IDDSI will be the only texture-modified diet recognized by NCM®.  The NDD and associated resources are no longer included in the NCM® after October 2021.
