OPTIPROT, Targeted Precision Nutrition for Protein Needs in Ageing

This multicenter, cross-sectional observational study aims to use precision nutrition tools to identify metabolic clusters in adults aged 50-75 years, enabling tailored nutritional and protein recommendations based on specific metabolic characteristics. Conducted at Eurecat-Reus (Catalonia) and AZTI (Bizkaia), the study will enroll 200 participants (75 at Eurecat, 125 at AZTI). Analyses will include metabolomics, gut microbiota profiling, epigenomics, and glycomics, with the goal of refining dietary guidelines and protein intake recommendations to address the specific needs of aging populations.
