A diet abundant in antioxidants, iron-chelating nutrients, and polyunsaturated fatty acids mitigates harmful iron accumulation in the brain, preserving cognitive function. www.sciencedirect.com
Although iron is essential for many physiological processes in the body, it can also be harmful, inducing oxidative stress and hindering neurogenesis. The body typically stores iron in protein complexes until needed, but these storage processes decline with age, leading to iron accumulation in body tissues. A recent study revealed that iron can build up in the brain, impairing cognitive function. Nevertheless, dietary components can help reduce iron accumulation in the brain and maintain cognitive health.
Researchers examined the brain health of 72 cognitively healthy older adults by conducting brain scans at baseline and two to three years later. Participants provided details about their dietary habits, physical activity, and overall health. They also underwent cognitive tests that evaluated their episodic memory and executive function.
The brain scans revealed that iron levels increased markedly over time, and higher iron accumulation correlated with poorer cognitive function. However, a higher intake of antioxidants, vitamins, iron-chelating nutrients, and polyunsaturated fatty acids mitigated iron accumulation. Iron-chelating nutrients include polyphenolic compounds, such as gallic acid and catechins (in tea), caffeic acid (in coffee), quercetin (in apples and onions), ellagic acid (in walnuts and pomegranates), curcumin (in turmeric) and others.
These findings suggest that diet mitigates iron accumulation in the brain, ultimately influencing cognitive health. Interestingly, alcohol can promote iron accumulation in the brain. Learn more in this episode featuring Dr. Rhonda Patrick.
