Which diet texture level is suitable for individuals with severely reduced oral preparatory function and should be spoon-thick or pudding-like?

The diet texture level suitable for individuals with severely reduced oral preparatory function that is spoon-thick or pudding-like is indeed the pureed level. This texture is specifically designed for those who have significant difficulties with chewing and swallowing, making it essential for ensuring safe intake of nutrients without risking aspiration or choking.

Pureed diets consist of foods that have been processed into a smooth, thick consistency, resembling pudding. This texture requires minimal oral manipulation, making it easier for individuals with compromised swallowing abilities to consume. It helps in achieving adequate nutrition while reducing the risk of complications associated with ingestion.

In contrast, the mechanically altered level involves foods that have been modified to be softer and easier to chew but still require some oral processing. The advanced level includes textures that are more challenging and require a greater degree of chewing, and a regular diet encompasses all types of foods without texture modifications, which would not be appropriate for someone with severely reduced oral preparatory function.
