What is a level 3 National Dysphagia Diet?

A level 3 National Dysphagia Diet includes moist foods in bite-sized pieces. These foods are easier for you to chew and swallow. Avoid foods that are hard, sticky, crunchy, or very dry. Your healthcare provider will tell you how long you need to follow this diet. He or she may also explain the International Dysphagia Diet Standardization Initiative (IDDSI). The IDDSI contains 8 levels, from the thinnest liquids and foods to the thickest. Foods from the National Dysphagia Diet level 3 diet are on IDDSI level 6. Your provider may show you how to use IDDSI guidelines to test the thickness of your food or liquid.

What do I need to know about liquids?

Your healthcare provider will tell you how thick your liquids need to be. This depends on your ability to swallow. For the IDDSI system, liquids are levels 0 through 4. Your healthcare provider will tell you if which liquids you can have. Liquids can be thickened, if needed, with thickeners, flour, cornstarch, or potato flakes. Foods that are liquid at room temperature should also be thickened. These include frozen malts, yogurt, milk shakes, eggnog, ice cream, and gelatin.

• Thin liquids flow quickly. These liquids take little or no effort to drink. Examples include water, non-fat milk, no-pulp juice, coffee, tea, and soft drinks. The IDDSI level for these liquids is 0 (thin).
• Slightly thick liquids are thicker than water but still flow through a bottle's nipple. A little more effort is needed to drink these liquids. The IDDSI level for these liquids is 1 (slightly thick).
• Nectar-thick liquids have the same thickness as vegetable juices and milkshakes. It should take some effort to drink the liquid through a straw. The IDDSI level for these liquids is 2 (mildly thick).
• Honey-thick liquids should be difficult to drink through a straw. The IDDSI level for these liquids is 3 (moderately thick).
• Pudding-thick liquids need to be eaten with a spoon. You should not be able to drink them through a straw. The IDDSI level for these liquids is 4 (extremely thick).

How do I prepare foods?

• Cut all food into small pieces. Pieces need to be smaller than 1 inch (2.54 cm).
• Moisten the food by adding gravy, sauce, vegetable or fruit juice, milk, or half and half. Pour sauce or gravy over bread slices or syrup over pancakes. Allow the food to soften and dissolve.
• Add dry milk powder to foods for extra protein and calories, if needed.
• Cook vegetables so they are tender enough to be mashed with a fork.
