Copper nutrition and biochemistry and human (patho)physiology.

Area of Science:

• Biochemistry
• Human Physiology
• Nutritional Science

Background:

• Copper is an essential trace mineral crucial for numerous physiological processes.
• Imbalances in copper homeostasis are linked to diseases like ischemic heart disease, neurodegenerative disorders, and non-alcoholic fatty liver disease (NAFLD).
• Copper's role in immune function and lipid metabolism is increasingly recognized.

Purpose of the Study:

• To highlight unanswered questions in copper biology and metabolism.
• To emphasize the need for better biomarkers for assessing copper status, especially in sub-clinical deficiency.
• To address the adequacy of current dietary recommendations for copper intake.

Main Methods:

• This review synthesizes current research on copper's physiological roles and its implications in various diseases.
• It identifies gaps in knowledge regarding copper metabolism and nutritional requirements.
• The abstract calls for further human balance and interventional studies.

Main Results:

• Copper homeostasis is critical for preventing various health conditions.
• Current understanding of copper's role in immunity and lipid metabolism is expanding.
• There is a potential need to re-evaluate copper dietary recommendations due to emerging evidence of deficiency.

Conclusions:

• Further research is essential to elucidate the precise roles of copper in human health and disease.
• Developing sensitive biomarkers for copper status is a priority.
• Revisiting and potentially revising Recommended Dietary Allowances (RDAs) for copper may be necessary.
