Food for thought: Study shows relation of key nutrients with slower brain aging

Researchers aim to understand brain health for better aging, particularly in preventing cognitive decline. A recent study in Nature Publishing Group Aging by the University of Nebraska-Lincoln and the University of Illinois at Urbana-Champaign delves into the role of specific nutrients in brain aging.

They examined 100 cognitively healthy individuals aged 65-75, analyzing their demographics, physical activity, cognitive assessments, MRI scans, and blood plasma for nutrient biomarkers. Results revealed two brain aging patterns—accelerated and slower-than-expected—with the latter linked to a unique nutrient profile.

Beneficial biomarkers included fatty acids, antioxidants, carotenoids, vitamin E forms, and choline, akin to the Mediterranean diet associated with healthy brain aging. Unlike prior studies reliant on food frequency questionnaires, this research integrated brain imaging, blood biomarkers, and cognitive assessments. It offers valuable insights for future therapies promoting brain health.
