Summary

This study is testing whether eating wild blueberry powder every day for 16 weeks can improve blood flow and insulin sensitivity in the brains of older adults. Researchers will use MRI scans to measure changes in 36 overweight volunteers aged 60-75. The goal is to understand how blueberries might help keep the brain healthy as we age.
