Researchers have found that incorporating specific nutrients into a regular diet may reduce iron buildup in the brain—a factor associated with cognitive decline in normal aging. In this project, researchers specifically looked at non-heme iron, which is critical for brain health. This type of iron does not bind with storage proteins and, with age and in excess, can contribute to oxidative stress, potentially affecting neuronal integrity and cognition. Excessive brain iron has been linked to poor cognitive performance, even in normal aging. "Despite mounting evidence connecting iron overload to negative cognitive outcomes, there are currently no established methods for reducing...
