Copper is an essential trace mineral present in all body tissues.
Diet - copper
Copper works with iron to help the body form red blood cells. It also helps keep the blood vessels, nerves, immune system, and bones healthy.
Oysters and other shellfish, whole grains, beans, nuts, potatoes, and organ meats (kidneys, liver) are good sources of copper. Dark leafy greens, dried fruits such as prunes, cocoa, black pepper, and yeast are also sources of copper in the diet.
Normally people have enough copper in the foods they eat. Menkes disease (kinky hair syndrome) is a very rare disorder of copper metabolism that is present before birth. It occurs in male infants.
Lack of copper may lead to anemia and osteoporosis.
In large amounts, copper is poisonous. A rare inherited disorder, Wilson's disease, causes deposits of copper in the liver, brain, and other organs. The increased copper in these tissues leads to hepatitis, kidney problems, brain disorders, and other problems.
The Food and Nutrition Board at the Institute of Medicine recommends the following dietary intake for copper:
