Copper: Copper is a part of several enzymes in the body. It is an antioxidant and plays an important part in the utilization of iron and formation of red blood cells. Copper deficiency is extremely rare and may occur in formula-fed premature babies. Copper deficiency leads to anemia, recurrent diarrhea and bone problems. Copper deficiency can also occur in a genetic disease such as Menke's disease (leads to hair and brain involvement).

Excess of copper in the body can occur when milk boiled and stored in brass utensils is consumed. It leads to a liver problem such as Indian Childhood Cirrhosis (ICC). Copper excess can also occur in a genetic disorder - Wilson's disease (characterized by liver, eye and brain problems). Diagnosis of copper deficiency can be established by measuring the blood copper levels. Copper excess can be determined by measuring the copper content in the organ that is involved.

Sources of Copper - Oysters, fish, whole grains, nuts, legumes, milk boiled and stored in brass utensils.
