About this Collection
Aging alters nutritional needs, metabolic processes, and susceptibility to chronic diseases. Malnutrition is common among older adults and contributes significantly to morbidity, functional decline, and healthcare costs.
This will be a Collection of original research papers and will be open for submissions from all authors – on the condition that the manuscripts fall within the scope of the Collection and of Scientific Reports more generally. We are welcoming submissions until 21st July 2026.
Hear from the Guest Editors
"The importance of nutritional diets that contain high protein yoghurt and whey protein may improve microbiota composition with effects on muscle function and strength in the elderly. Dietary protein intake is important to maintain the amino acid balance and to reduce the mortality in kidney failure patients with the aging process. As a Guest Editor I have been most interested in the scope and themes of the Collection. The invitation of top experts and contributors in this field to submit their research work is of importance to the success of this edition. The coordination by the Editors and Reviewers with relevance to the evaluation and revision process has ensured the publication's standards for the Scientific Reports journal. Future submissions may involve nutrition therapy that may reverse the acceleration of the aging process and halt the global diabetes and neurodegenerative disease epidemic."

Contribution highlights
Low Fischer’s ratio is associated with increased mortality in patients with kidney failure
Low Fischer’s ratio — a marker of amino‑acid imbalance — strongly predicts higher mortality in patients with kidney failure. This study shows that disrupted amino‑acid metabolism may be an under‑recognised risk factor, highlighting its potential value for clinical risk stratification and nutritional intervention research.
Protein yogurt and whey protein lead to similar muscle gains in older adults, but they cause distinct shifts in the gut microbiome during strength training. These findings suggest that while both proteins support muscle development, their different effects on gut bacteria may influence long‑term metabolic health and personalised nutrition strategies for ageing populations.
