Final answer:
The least restrictive level of the National Dysphagia Diet (NDD) is Level 1, also known as the Dysphagia-Pureed diet. This diet consists of pureed foods that are easier to swallow and require less chewing. It is recommended for individuals with severe swallowing difficulties.
Step-by-step explanation:
The National Dysphagia Diet (NDD) is a diet classification system that categorizes foods and liquids based on their texture and consistency for individuals with swallowing difficulties. The least restrictive level of the NDD is Level 1, which is also known as the Dysphagia-Pureed diet. This diet consists of food that has been pureed to a smooth, cohesive texture, and it is often recommended for individuals with severe swallowing difficulties. The pureed food is easier to swallow and requires less chewing and manipulation in the mouth.
For example, pureed foods can include mashed potatoes, pureed vegetables, and smoothly blended soups. The Dysphagia-Pureed diet helps to maintain adequate nutrition and hydration while minimizing the risk of aspiration, which is when food or liquid enters the airway instead of going down into the stomach.
Although the Dysphagia-Pureed diet is the least restrictive level of the NDD, it is important to note that individuals with dysphagia may have different swallowing difficulties, and the appropriate diet level should be determined by a healthcare professional or speech-language pathologist based on the individual's specific needs.
