Copper in health
Copper is an essential trace element that is vital to the health of all living things (humans, plants, animals, and microorganisms). In humans, copper is essential to the proper functioning of organs and metabolic processes. The human body has complex homeostatic mechanisms which attempt to ensure a constant supply of available copper, while eliminating excess copper whenever this occurs. However, like all essential elements and nutrients, too much or too little nutritional ingestion of copper can result in a corresponding condition of copper excess or deficiency in the body, each of which has its own unique set of adverse health effects.Daily dietary standards for copper have been set by various health agencies around the world. Standards adopted by some nations recommend different copper intake levels for adults, pregnant women, infants, and children, corresponding to the varying need for copper during different stages of life.Copper deficiency and toxicity can be either of genetic or non-genetic origin. The study of copper's genetic diseases, which are the focus of intense international research activity, has shed insight into how human bodies use copper, and why it is important as an essential micronutrient. The studies have also resulted in successful treatments for genetic copper excess conditions, enabling patients whose lives were once jeopardized to live long and productive lives.Researchers specializing in the fields of microbiology, toxicology, nutrition, and health risk assessments are working together to define the precise copper levels that are required for essentiality, while avoiding deficient or excess copper intakes. Results from these studies are expected to be used to fine-tune governmental dietary recommendation programs which are designed to help protect public health.
