A Summary of The Latest Medical News: A recent study reveals that **moderate dietary copper intake** may help protect brain health in older adults, boosting cognitive function up to a certain level[1][2][3][4]. **Optimal Amount of Copper for Brain Health** Researchers analyzed health data from 2,420 Americans aged 60 or older to explore the link between dietary copper and cognition. They found optimal cognitive test scores with daily copper intake in the range of **1.2 to 1.6 milligrams per day**. Going beyond this amount did not yield further brain benefits[2][3][4]. **How Copper Supports the Brain** Copper is crucial for the brain’s energy metabolism, neurotransmitter production, and antioxidant defenses. As a cofactor for enzymes such as superoxide dismutase, copper helps neutralize harmful free radicals that can damage brain tissue, especially as we age[4]. **Cognitive Tests and Observed Benefits** Participants consuming moderate copper showed better results on several cognitive measures: - **Digit Symbol Substitution Test (DSST):** Processing speed peaked at about 1.6 mg/day copper[2][4]. - **Animal Fluency Test (AFT):** Verbal fluency was best at approximately 1.4 mg/day copper[2][4]. - **Global Cognition Z Score:** Maximum benefit appeared around 1.2 mg/day copper[2][4]. Those with a history of stroke benefitted most, possibly because copper reduces post-stroke inflammation and aids neuron repair[3]. **Balancing Copper Intake: Not Too Little, Not Too Much** Both copper deficiency and excess pose risks. Too little copper may impair synaptic connections and energy production in the brain, while too much can increase oxidative damage and inflammation, which can be harmful[4]. **Limitations of the Study** It’s important to note that the findings are based on self-reported dietary data, which rely on participants remembering what they ate in the last 24 hours. This method can introduce error, and as the study was observational, it cannot prove that copper directly boosts brain health. Long-term follow-up is needed to further clarify the relationship[1][2][3]. **A Cautious Take on Copper and Cognition** The new research adds to a growing body of evidence suggesting that getting the right amount of copper in your diet may play a role in maintaining cognitive sharpness—especially as we age. However, more research is needed before making specific dietary recommendations. In the meantime, focusing on a balanced diet that includes moderate amounts of copper-rich foods, such as nuts, seeds, shellfish, and whole grains, may support overall health and well-being[1][3][4].
