A greater adherence to the Mediterranean diet which had been assessed through an index made with biomarkers during a 20-year scientific monitoring is associated with a lower mortality in adults over 65. This is one of the main conclusions of a study led by Cristina Andrés-Lacueva, head of the Research Group on Biomarkers and Nutritional & Food Metabolomics of the Faculty of Pharmacy and Food Sciences of the University of Barcelona (UB) in Barcelona (Spain, Catalonia)and the CIBER on Fragility and Healthy Ageing (CIBERFES), also formed by the Food Innovation Network of Catalonia (XIA).
The study is based on the InCHIANTI project, conducted in the region of the Italian Tuscany, a study that has been carried out during twenty years in a total of 642 participants (56% women) aged over 65 or more and which enabled researchers to obtain complete data on food biomarkers.
This study highlights the use of dietary biomarkers to improve the nutritional assessment and guide a customized assessment for older people. As noted by the CIBERFES researcher of the UB Tomás Meroño, co-first signatory of the study, the researchers “confirm that an adherence to the Mediterranean diet assessed by a panel of dietary biomarkers is inversely associated with the long-term mortality in older adults, which supports the use of these biomarkers in monitoring evaluations to study the health benefits associated with the Mediterranean diet”.
