The use of Mechanical Soft Diet is for individuals who have difficulty chewing but are able to tolerate a wide variety of foods. Modifications in the diet need to be individualized according to the patient’s needs.
This diet may be used for residents with missing teeth, ill-fitting dentures, general debility or weakness, and other chewing problems; it may be useful for patients with esophageal stricture (narrowing of the esophagus).

chopping, mincing, or mashing. The diet includes foods soft in texture 
such as cooked fruits and vegetables, moist ground meat, and soft bread

mouth such as graham crackers and some ready-to-eat cereals are also 
appropriate. It is most important to individualize or adjust it to the 
tolerance of the resident.
