A new prospective study has provided more definitive evidence linking the Mediterranean diet to a deceleration in cognitive decline among older individuals.
The study departed from the reliance on self-reported dietary data, a common limitation in previous research (Source: Medical News Today). Instead, blood serum biomarkers were employed to gauge participants’ adherence to the Mediterranean diet, offering a more accurate measurement of their dietary intake.
The study, conducted in two French regions, utilized a nested case-control design to minimize bias. By measuring metabolites in blood samples taken at baseline, researchers established an MDMS (Mediterranean Diet Metabolomic Score) to assess adherence. The results indicated that individuals with higher MDMS scores were 10% less likely to develop mild cognitive impairment in Bordeaux and 9% less likely in Dijon.
Published in the journal Molecular Nutrition and Food Research, this research encourages a shift toward biomarker-based assessments for a more accurate understanding of the impact of dietary patterns on cognitive well-being. As the field advances, this study provides valuable insights into the potential benefits of the Mediterranean diet and its role in mitigating age-related cognitive decline.
Unlike previous studies examining the link between diet and cognitive decline, the approach in this research sets a new standard by using blood serum biomarkers. The study focuses on the Mediterranean diet, known for its potential health benefits, to address the increasing global aging population and the projected rise in dementia cases.
The World Health Organization estimates that the global population over the age of 60 will nearly double by 2050. With expectations of over 152 million people developing dementia by 2050, especially Alzheimer’s disease, researchers emphasize the urgency of exploring alternative options beyond pharmaceutical interventions.
Dr. Perlmutter underscores the critical role of diet in the context of cognitive decline, emphasizing the limited efficacy of pharmaceuticals in preventing or significantly improving cognition in diagnosed cases of dementia. The study’s findings highlight the importance of dietary choices in promoting cognitive health as the global population ages.
