Dysphagia Diet: Understanding the Categorization

A dysphagia diet is a diet in which food or drinks are modified to help with the swallowing process due to issues swallowing. Swallowing difficulties can be caused by various factors, such as neurological disorders, structural issues in the throat or esophagus, or certain medical treatments.

The main objective of a dysphagia diet is to ensure that individuals with swallowing difficulties can safely and comfortably consume food and liquids while minimizing the risk of choking or aspiration (when food or liquids enter the airway instead of the digestive tract). Dysphagia diets are typically prescribed by healthcare professionals, such as speech-language pathologists, based on the severity and underlying cause of the swallowing impairment.

The diets is often categorized into different levels, with each level indicating the texture and consistency of foods and liquids allowed for the particular person’s needs. The levels can vary in terms of thickness, viscosity, and ease of swallowing. The exact terminology might differ depending on the specific guidelines used (IDDSI.org is an excellent resource), but here's a general overview for foods and liquids:


Level 0: Dysphagia Level 0 Liquids: Beverages do not need any altercation and can be consumed thin, flows like water.

Level 1: Dysphagia Level 1 Liquids Slightly Thick: Beverages should be slightly thicker than water and would require a little more effort to consume. Perhaps to the consistency for milk or infant formula.

Level 2: Dysphagia Level 2 Beverages Mildly Thick: Beverages should easily flow off a spoon, but slower than thin liquid.

Level 3: Dysphagia Level 3 Beverages Moderately Thick: These beverages can be consumed from a cup, and it would require moderate effort to suck through a straw.

Level 4: Dysphagia Level 4 Beverages Extremely Thick: Beverages are very thick and it might be easiest to consume with a spoon. This is the level in which Naturally Thick beverages are produced. They are packages in a malleable container with a spout to easily be consumed from the package to one’s mouth.


Level 3: Liquidized Food: Food at this level can we eaten with a spoon, but no oral processing is required. This is the first level where foods and liquids overlap.

Level 4: Pureed: Foods are pureed to a smooth, cohesive texture with no lumps. They should be easily swallowed without the need for chewing. Examples include smooth pureed vegetables, fruits, and meats. This is the second and final level where liquids and food overlap.

Level 5: Minced and Moist Alterations: Foods are moist and soft, but not necessarily pureed. They should be easy to mash with a fork or easily broken down in the mouth.

Level 6: Soft and Bite Sized: Foods are chopped into small, bite-sized pieces that require more chewing. However, this level still requires foods that soft and easy to manage, but no items in which thin liquids can separate.

Level 7: Regular Diet with Modifications: This level involves eating a regular diet of various textures but paying attention to what is appropriate for the age and development of the individual.

It's important that the appropriate dysphagia diet level will depend on the individual's swallowing abilities/needs, and the diet plan may need to be adjusted over time as the person's condition improves or changes. It’s so important to work with a healthcare professional, I.e. a speech-language pathologist, to understand and determine the most suitable dysphagia diet for each person's needs.
