In vitro digestion of protein-rich dairy products in the ageing gastrointestinal tract
Abstract
Interest for specific populations – Older adults
Insufficient protein intake can lead to sarcopenia, characterized by the loss of muscle
mass, strength, and function.
• Healthy older adults (> 65 y.) need to increase the amount of high-quality proteins in
their diet (1 g protein /kg body weight /day). ESPEN guidelines
• Ageing leads to changes in the functionality of the digestive tract but the impact of
ageing on digestion, and absorption of nutrients is still unclear (Lee et al., 2021).
