Vitamin C supports brain structure and memory in adults over 60, study finds

Researchers at Japan's University of Hirosaki analysed MRI scans and blood samples from 2,044 adults aged over 64. Participants with lower plasma vitamin C levels showed reduced gray‑matter volume and weaker connectivity in the brain's default‑mode network, while those with adequate vitamin C preserved these structures. The study, published in PLOS One, recommends regular intake of vitamin‑C‑rich foods such as citrus fruits, kiwi, acerola, guava, broccoli, kale and yellow peppers to help maintain brain health in older age.

Separately, health experts outline eight practical signs of healthy aging after 65, including stable walking and balance, effortless stair climbing, efficient everyday memory, restful sleep, normal appetite and digestion, active social engagement, and independence in daily tasks. Maintaining these abilities is linked to better physical, cognitive and emotional well‑being for seniors.
