Results of a recently-published study suggest what we eat may help protect our brains from iron accumulation and associated cognitive decline.
Researchers assessed the nutrient intake of 73 healthy adults ages 61 to 86 years. They assessed participants’ brain iron concentrations (using non-invasive scans) and tested their memory. Participants who consumed more foods (like plant oils) rich in omega-3 and omega-6 fatty acids and vitamin E, as well as the amino acid lysine, had lower brain iron concentrations and better working memory performance.
While these results are observational, consuming nuts, plant oils like soybean, olive, canola, and sunflower oil, and fish has consistently been associated with better overall health. Enjoy these foods as part of a healthy dietary pattern, and you may be protecting your brain in the process!
