Oral Processing and Appetite in Older Adults

University of Reading88 enrolled

Overview

The goal of this observational study is to learn about changes in oral processing and appetite in older adults aged 65+ years old. The main question it aims to answer is if oral processing affects gastric emptying in older adults (≥65 years old).

* To investigate if food intake and satiety differ between faster and slower eaters, within older adults (≥65 years old). * To assess if chewing rate, salivary flow rate, oral processing and gastric emptying differ between older adults (≥65 years old) with smaller versus bigger appetites.
