FortiPhy: Protein Bioavailability, Satiety and Appetite

Summary

Older adults have very specific food and nutrient requirements and often struggle to meet these needs due to poor appetite, reduced functionality and dexterity. Protein (both quality and quantity) is an important macronutrient in maintaining muscle in older adults which can help prevent falls, delay disease onset and help individuals maintain independence. Fortifying regular/ everyday foods with additional protein is one strategy to help older adults meet these increased protein needs. However, it is well established that protein is the most satiating of the nutrients we eat, yet less is known about how this is impacted by age and protein type. This study aims to test 2 protein fortified porridge recipes in older adults (and a control recipe) with outcomes focused on protein bioavailability, appetite and satiety responses.
