Time for IDDSI Updates

By: Karen Sheffler

July 28, 2022

Iddsi launched in the US May 1, 2019. See this launch date advertised at the Dysphagia Research Society meeting in 2019 by Karen Sheffler (of SwallowStudy.com) and Peter Lam (an IDDSI co-chair).

IDDSI launched in in the USA per ASHA and the AND in May 2019. Then COVID-19 hit. Where are you now with IDDSI implementation?

7 IDDSI Updates

by Karen Sheffler, MS, CCC-SLP, BCS-S of SwallowStudy.com

Did you know that over well over 40 nations around the world have started to implement IDDSI and formed nationwide work groups (aka, reference groups). It is inspiring to have global IDDSI meetings with large nations like Brazil, Mexico, Canada, and China, as well as smaller nations such as Iceland and Myanmar! The newest countries to join are: Azerbaijan, Portugal, and the United Arab Emirates. It truly is a global wave of standardization of food and liquid textures and dysphagia diets for the safety of people of all ages, in all settings, and across all cultures.

The American Speech-Language and Hearing Association (ASHA) along with the Academy of Nutrition and Dietetics (AND) declared that May 1, 2019 would be the official launch date for IDDSI in the USA. Then COVID-19 hit! Many facilities that were deep in the middle of IDDSI implementation were derailed. In the United States, the United States IDDSI Reference Group (USIRG) formed in early 2021 to support implementation across the nation with a large group of active volunteers who are generating resources and answering questions.

I am on the USIRG’s Communication & Advocacy and Resources & Best Practice work groups. We have been busy! Regarding resource development, we are curating and creating resources that are US-specific. We have been trying to gather resources that facilities have already created. We hope that organizations/facilities around the nation are keeping up with IDDSI updates and sharing with other facilities. It would be nice to not have everyone re-invent the wheel. However, some proprietary regulations in some healthcare organizations have prevented faster dissemination of those resources and handouts. If you are able to share with others around the nation, please contact usa@iddsi.org. You can also contact usa@iddsi.org to ask questions and provide ideas on what resources need to be developed.

Feel free to join one of our 4 committees as seen here:

United States IDDSI Reference Group (USIRG) formed in 2021 to keep up with IDDSI Updates and help the nation with IDDSI implementation. These are our four committees and email contact. Volunteer, ask questions, and plug in to help!

7 IDDSI Updates & Encouragement to Connect

It has been a little while since my last IDDSI Resources blog. Please check that out that resource for many links to documents on the www.IDDSI.org website, as well as a long list of my prior IDDSI blogs dating back to 2014!
When you come back and are ready for more,
here are my latest IDDSI updates:

1. USIRG IDDSI Chart of Many Resources:

Go to —> https://iddsi.org/United-States

Check this United States chart often, as we are adding to it frequently. I highly recommend checking out the resources of other countries that are also listed on the www.IDDSI.org homepage.
Here are some examples of our USIRG resources (which can be used/translated as needed by other countries):
  • USIRG IDDSI Webinars (see section #4 of the US chart): So far we have three IDDSI 101 PowerPoints for Food Service Workers & Caregivers, Healthcare Professionals, and Administrators. These are easy and quick introductions to IDDSI. The links bring you to a YouTube video where the USIRG speaker guides you through the PowerPoints.
    • Our IDDSI 201 Webinars will train the IDDSI Testing Methods across the whole framework. They will be recorded and posted soon. There will be a 201 for Food Service Workers and a more in depth 201 for Healthcare Workers (RDNs, CDMs, SLPs, etc.).
  • USIRG Best Practice IDDSI Terminology (Powerpoint): It is so important to use IDDSI approved terminology. This PowerPoint teaches how it is best practice to use two identifiers when discussing or writing about the IDDSI levels. (We use two identifiers with our patients of name and date of birth and/or medical record number, so IDDSI does the same to avoid confusion). For example: Mildly Thick, Level 2; Minced & Moist, Level 5; Soft & Bite-Sized, Level 6. We cannot change these descriptive labels. For examples, a Minced diet definitely needs Moist attached to it to make it safe. Level 6 needs to be written as “Soft & Bite-Sized” as both of those terms appropriately describe how that diet can mitigate (reduce) a choking risk; the food needs to pass the Fork Pressure Test for “soft” and needs to pass the bite-size of 1.5cm to not block an airway (see Testing Methods details here). This Terminology PowerPoint also provides the 3-character approved abbreviations for your computer systems.
  • Competencies: It is important to document the training that you and your coworkers are undertaking in IDDSI. We have completed the competency quizzes for some of the 101 trainings:
  • Current Resource & Best Practice work group projects include:
    • Making the IDDSI Patient Handouts more user friendly to the United States audience. (They were written with some British-English vocabulary, such as Lollies, Biscuits, and Crisps!).
    • Cataloguing over 500 articles into an IDDSI literature evidence table.
I will keep you all posted on IDDSI Updates & new links above.

Readiness for IDDSI Updates starts with knowing the IDDSI framework with pyramids for solids and drinks/liquids, along with the sidebar for transitional foods. Each IDDSI level has a name, color, number and triangle icon. Use at least two identifiers when talking or writing about IDDSI levels, such as Mildly Thick Liquid, Level 2.

4. Food Scientists & Chefs Train IDDSI:

a. IDDSI Webinar on Myths & Truths:

Peter Lam (IDDSI co-chair) hosted this myth busting online event with expert rheologist and IDDSI Testing guru Dr. Ben Hanson and dysphagia culinary and foodservice specialists Preston Walker and James Ball from Oak House Kitchen. The live panel discussion will cover the science involved and the culinary know-how behind making food for the IDDSI Framework. Go to IDDSI’s YouTube Link: https://youtu.be/mQ75b7sKxtU.

b. More IDDSI & Oak House Kitchen Webinars:

  • The Science Behind IDDSI: Dr. Hanson, IDDSI Board Director, is joined by Peter Lam (IDDSI Co-Chair), and discusses the science and methodology behind IDDSI testing methods
  • Myths and Truths about Modifying Foods for IDDSI levels. Preston Walker and James Ball, of Oak House Kitchen, have been training healthcare catering for over 10 years. Their current focus in this field is on the transition to the IDDSI standards and have been working on how best to achieve this.

c. Rubiconfoods.com

Some chefs and dietitians from the USIRG and Rubicon Foods have teamed up with Pineapple Academy, LLC to make quick videos on how to prepare foods and drinks IDDSI-style. To see examples of how to puree, vacuum seal, shape and plate meats to prepare a perfect Pureed, Level 4, check out this free sneak peak to their trainings: www.rubiconfoods.com/iddsi/.

5. E-Bites & IDDSI website: Stay Informed of Any IDDSI Updates & Events

  • Sign up for IDDSI Global’s e-bites / newsletters
  • Check out the e-bites for the USIRG at the bottom of our resources chart here: https://iddsi.org/United-States.
  • Follow IDDSI on social media: Twitter, Instagram, LinkedIN
  • Follow IDDSI on YouTube for great food and drink testing videos and many webinars. These cover IDDSI across all ages and the continuum of care. These will help you train your staff. Many of these food and drink testing demonstrations have been translated into other languages. My favorite one to add to training PowerPoints is the beginning of this one that covers some of the choking dangers of bread: https://youtu.be/W7bOufqmz18
  • Download the IDDSI app. You can even use this in a person’s home to train the person with dysphagia and their caregivers. Once the content is downloaded, you can view it without the use of wifi.
  • Check out popular IDDSI training posters.
  • IDDSI has been translated into 20 languages so far. See available translations and how you can help expand this list.

6. Keep Asking Questions, such as:

Is IDDSI Mandatory? Do I have to Change?

Can you give me a list of IDDSI approved foods?

I will answer these questions with slides from my PowerPoints that answer them in a pretty way! Here is a link from IDDSI.org, sharing about how IDDSI is now the only professionally-recognized standard of care.

Feel free to use any images or let me know if you need PowerPoint content. IDDSI’s mission has always been to make content free and accessible around the world.

This answers if IDDSI is mandatory. It is not considered mandatory, but it is NOW the only professionally-recognized dysphagia diet framework. Changing to IDDSI is important to stay up-to-date with evidence-based standard of care.

Can IDDSI provide a list of IDDSI-approved foods for each IDDSI level? No, as it is dependent on the testing methods and food and drink characteristics of each level. IDDSI is global and can be used to analyze foods and drinks from around the world.


We need to clear up common confusions and misunderstandings about what IDDSI is:

      • IDDSI does not mandate what patients are or are not allowed to have. That is a decision to be made by the whole medical team, of which the person with dysphagia is the driver. IDDSI pairs with person-centered care well.
      • IDDSI does not mandate what you as a dysphagia clinician or registered dietitian recommend for the person with dysphagia.
      • IDDSI is a set of standardized labels, descriptors and definitions for foods (regular through puree) and drinks (thin liquid through extremely thick).
      • IDDSI provides testing methods to prepare and test foods to standardize what is potentially easier and safer for an individual with difficulty chewing, swallowing or clearing foods through the mouth, throat and esophagus.
      • IDDSI is a tool to help you clearly discuss options related to consuming foods and liquids.
        • We finally are all talking the same language, understanding what we mean by “soft,” “puree,” “thick liquid,” “easy to chew,” and more.
        • Old diet labels (such as “mechanical soft”) have no standard definitions and have been the source of numerous choking deaths around the country.
        • Old diet systems (such as National Dysphagia Diet) were too subjective and did not have testing methods or descriptors based on evidence.
        • Read more on Why IDDSI? in this mission statement found in our USIRG resource chart.
      • Clinicians have a conversation with the person (and/or healthcare proxy if the person is deemed unable to make complex decisions).
        • IDDSI does not dictate what is best or safest for the person. One cannot prevent aspiration and/or choking 100% of the time. We offer options to mitigate risks, though.
        • Clinicians use their clinical judgement, expertise, evidence-based practice, guidance from comprehensive dysphagia evaluations (that may include instrumental evaluations) to make recommendations.
        • Clinicians provide options (aggressive through palliative, as appropriate). We provide education, counseling, and potential prognostic information (i.e., are you having difficulty swallowing, what can we do about it, and how long will it take to get better?). Sometimes we recommend diet modifications temporarily for very acute problems while waiting for further testing, resolution of symptoms, and/or for a targeted therapy program to hopefully improve the swallowing and mealtime success. Sometimes diet modifications are needed more long-term. Each person is an individual.
        • The medical team, which includes the person with dysphagia, discusses and considers options. It is the person (or healthcare proxy) who makes the informed decision on care without coercion of waiver forms (which have been used when a person does not agree with the recommendations of a healthcare provider, who is not using person-centered care). 
Do you have other questions? See IDDSI’s FAQs already posted.
See USIRG’s Frequently Asked Questions section (#5 in chart) for answers that have been carefully crafted by our group of SLPs, dietitians, and food service professionals. More FAQ topics will be added as we process them.
