What's Happening?
A new study published in Scientific Reports has found a potential link between copper intake and improved cognitive function in older adults. Conducted by four anesthesiologists in China, the research analyzed health data from 2,420 adults aged 60 and older, collected between 2011 and 2014. Participants reported their dietary habits and underwent cognitive tests. The study concluded that higher copper intake was associated with better cognitive performance, particularly in individuals who had previously suffered a stroke. However, the researchers caution that excessive copper can be toxic, suggesting an optimal daily intake slightly above the current Recommended Dietary Allowance.
Why It's Important?
As global dementia cases are projected to rise significantly, this study highlights the potential role of dietary copper in maintaining cognitive health among older adults. The findings could influence dietary recommendations and public health strategies aimed at preventing cognitive decline and neurodegenerative diseases. By identifying copper as a key micronutrient, the study encourages a balanced diet rich in copper-containing foods, which could benefit the aging population. However, it also warns against excessive intake, emphasizing the need for careful dietary planning.
