Iron is a vital mineral for brain health, but excessive accumulation can contribute to cognitive decline as we age.
Recent research from the University of Kentucky suggests that our diet may play a crucial role in maintaining a delicate balance of iron in the brain.
A 3-year study of 72 older adults used specialized MRI techniques to track iron accumulation in the brain, revealing a buildup in regions responsible for memory and problem-solving.
However, the study found that participants who consumed more antioxidants, vitamins, and iron-chelating nutrients showed significantly less iron accumulation.
These individuals also maintained better memory and executive function over time.
According to Dr. Valentinos Zachariou, who led the study, “The significance of this finding lies in the possibility that brain iron accumulation during aging may not be an inevitable process but one that could be influenced by dietary choices.”
The study’s findings suggest that a diet rich in antioxidants, vitamins, and iron-chelating nutrients may help regulate brain iron levels, potentially reducing the risk of cognitive decline.
As Dr. Zachariou noted, this discovery offers hope that individuals can take proactive steps to support their brain health through informed dietary choices.
