Too much iron can age the brain. Here’s what diet can do about it. |
Iron is essential for brain health — until it isn’t. As we age, this vital mineral can accumulate in our brains, potentially contributing to cognitive decline. But new research suggests our diet might help keep this delicate balance in check.
In a 3-year study, University of Kentucky researchers tracked iron accumulation in the brains of 72 older adults using specialized MRI techniques. They found that iron built up in regions crucial for memory and problem-solving.
However, participants who consumed more antioxidants, vitamins, and iron-chelating nutrients showed significantly less accumulation. Those with less iron buildup maintained better memory and executive function over time.
“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,” explained Dr. Valentinos Zachariou, who led the study.
