The analysis of plasma samples indicated that some metabolites are related to the progression of cognitive impairment and dementia. The results reveal a protective association between metabolites derived from cocoa, coffee, mushrooms and red wine, microbial metabolism of polyphenol-rich foods (apple, cocoa, green tea, blueberries, oranges or pomegranates) and cognitive impairment in the elderly. As Mireia Urpí-Sardà, from the Department of Nutrition, Food Science and Gastronomy and CIBERFES, notes, "what we analysed in the cohorts under study is the modulating role of the diet in the risk of suffering cognitive impairment." Urpí-Sardà points out that "the results show a significant association between these processes and certain metabolites." The study analyses the relationship between the metabolism of dietary components, intestinal microbiota, endogenous metabolism and cognitive impairment. Metabolomics to study the impact of diet on health This European study, part of the Joint Programming Initiative "A Healthy Diet for a Healthy Life" (JPI HDHL), was carried out over 12 years with the participation of 842 people aged over 65 in the Bordeaux and Dijon regions (France). The paper, published in the journal Molecular Nutrition and Food Research, is led by Cristina Andrés-Lacueva, professor at the Faculty of Pharmacy and Food Sciences and head of the Biomarkers and Nutritional Metabolomics of Food Research Group of the UB and the Biomedical Research Network Center in Frailty and Healthy Aging (CIBERFES), which is also part of the Food Innovation Network of Catalonia (XIA).
