Muscle protein synthesis
Achtergrond van het onderzoek
A major cause of global environmental change is food production, with animal based food products having the greatest impact on the environment. Therefore, consumers are increasingly encouraged to consume more plant-based foods and lower their consumption of foods from animal origin. However, the consequences of such a transition on muscle mass still remains to be explored. This is of particular importance in the older population, where sarcopenia is highly prevalent. Therefore, we aim to investigate the short-term effect of a vegan diet on daily muscle fractional synthesis rates in comparison to an omnivorous diet in community-dwelling older adults. The study will have a randomized controlled cross-over design and will include healthy older adults, aged 65-79 years.
Doel van het onderzoek
The vegan diet will differently affect muscle protein synthesis rates in older adults than the omnivorous diet.
