“We developed a dietary biomarker based on the food groups included in the Mediterranean diet and they I evaluated their association with mortality.
In this study, the researchers selected reference levels of the following dietary biomarkers in urine: total polyphenols and the metabolite resveratrol (from grape intake) and blood concentrations. plasma, carotenoids, selenium, vitamin B12, fatty acids, and their ratios of monounsaturated and saturated fatty acids. They used a predictive model and are evaluating the association of the Mediterranean diet index and food frequency questionnaire (FFQ) with mortality.
During the years of study follow-up, there were 425 deaths (139 from cardiovascular diseases and 89 from cancer-related causes). After the models were analyzed, scores of the Mediterranean diet using biomarkers were inversely associated with all-cause mortality.
This study therefore emphasizes the use of dietary biomarkers to improve the assessment of nutritional factors and guide it for older adults. As noted by UB CIBERFES researcher Toms Meroo, the study’s first co-signer, the researchers “confirmed that adherence to the Mediterranean diet was assessed by a panel of biomarkers Studies of diet are inversely associated with long-term mortality in older adults, supporting the use of these biomarkers in follow-up evaluation to study the associated health benefits. to the Mediterranean diet.”
