Scientists have identified a link between copper in the diet and memory retention
The nutrients found in everyday foods may play an important role in slowing cognitive decline in the elderly. This is evidenced by the data of a study published on the Medical Xpress portal.
The authors analyzed data from older Americans, recording their diets through detailed nutrition diaries and comparing them with the results of memory and attention tests. It turned out that participants whose diets regularly included copper—rich foods, such as nuts, shellfish, and dark chocolate, showed higher cognitive results.
At the same time, the study also revealed limitations. The group with increased copper intake was predominantly represented by men with higher income and education, without bad habits and concomitant diagnoses such as hypertension or diabetes. This may indicate that nutrition is not the only factor affecting brain function in old age.
Scientists emphasize that full access to high-quality food and medical care can improve cognitive performance, regardless of the level of copper in the diet. However, according to the portal, improving nutrition is especially important for representatives of socially vulnerable groups.
Other work in this field confirms the potential role of copper in maintaining mental abilities. One study showed that cognitive decline progressed faster over time in people with copper deficiency. It was found that with a higher content of this trace element, memory deterioration occurred more slowly, and there was also a lower accumulation of plaques associated with Alzheimer's disease.
At the same time, as scientists specify, the level of copper in brain tissues does not always reflect its consumption with food. The biological mechanisms of assimilation of this trace element remain complex and insufficiently studied.
It is noted that copper is necessary for energy production in brain cells, transmission of nerve impulses and protection from oxidative stress. Deficiency of this element can be manifested by chronic fatigue, anemia, weakened immunity, and even neurological disorders.
Meanwhile, experts warn against uncontrolled intake of copper additives. Excessive intake of this trace element, as well as iron, can cause oxidative stress and damage to neurons. It is especially important to maintain a balance between copper, zinc and iron, as a violation of the proportions between them can negatively affect the health of the brain.
Ilnur Zubairov, a rheumatologist, doctor of preventive and integrative medicine, and expert at Solgar, told Izvestia on April 7 that calcium is an important mineral for maintaining bone strength, supporting muscle function, and regulating nerve impulses. Calcium deficiency can lead to muscle spasms and cramps, numbness and tingling in the hands and feet, especially in the fingers and toes. Fatigue and weakness may occur, as calcium is involved in energy production.
