Abstract
Dysphagia is a combination of symptoms affecting a person’s ability to swallow. On the other hand, swallowing is about transferring of liquids and boluses from the mouth into the stomach. Boluses may have several solid-like consistencies and drinks may have different viscosities. Because rheology is the study of the deformation and flow of matter; the connection between swallowing and rheology and thus dysphagia is clear. This rheology science helps to better understand how a bolus is deformed and thus flowing during the swallowing process. Knowledge of the deformability and flow of a bolus is important to better understand dysphagia, or swallowing impairment. This chapter is organized as follows. Section 2 gives a short description of the material functions or rheological properties. Rheological data of products used for dysphagia are used as examples. Section 3 focuses on the rheological aspects of oral processing and bolus transportation. This is followed by a practical example on how to design new products for the nutritional management of dysphagic patients. The chapter ends with some concluding remarks.
