A recent study in Molecular Nutrition and Food Research found a direct link between sticking to the Mediterranean diet and a lower risk of cognitive decline in older adults. Unlike previous research relying on self-reported diets, this study used blood biomarkers to measure adherence to the diet, revealing a 10% decrease in mild cognitive impairment risk in one region and 9% in another among those with higher adherence scores over 12 years. This approach, focusing on metabolites, offers more reliable evidence supporting the diet’s cognitive benefits.
What are your thoughts on the use of blood biomarkers and metabolomics in dietary studies?
