“Nutrient Intake, Brain Structure, and Cognitive Function: New Study Shows Link for Healthy Aging”

A new study conducted by scientists from the University of Illinois Urbana-Champaign has revealed a strong correlation between nutrient intake, brain structure, and cognitive function, all of which are independently known to predict healthy aging. Published in the Journal of Nutrition, the study found that blood markers of saturated fatty acids, omega-6, -7 and -9 fatty acids were linked to better scores on memory tests and larger brain structures in multiple regions. By using a data-fusion approach to combine MRI scans of brain structures, biomarkers of 52 dietary nutrients, and cognitive performance tests in 111 healthy older adults, the researchers were able to identify dozens of traits that work together to promote brain and cognitive health in older adults. The data-fusion approach allowed the researchers to look at relationships among all of these factors together and overcome some of the limitations of analyzing individual factors. Researchers emphasized that while the study only implies an association between dietary habits and brain health, it highlights the importance of nutrition in healthy aging.
