High-Protein Diet, Strength Training and Gut Microbiota in Aging

This study aimed to investigate whether increasing protein intake through regular foods, combined with strength training, affects the gut microbiota in community-dwelling older adults (65-85 years). With an aging population, maintaining muscle mass and function is crucial for healthy ageing, and higher protein intake is often recommended. However, there are concerns about how such dietary changes might influence gut health. By examining the effects of different protein levels and resistance training on the gastrointestinal microbiota, this research addresses an important question for nutritional strategies aimed at supporting the health and well-being of older adults. Sequencing was performed at the Joint Microbiome Facility of the Medical University of Vienna and the University of Vienna under the project ID JMF-1901-3.
