Copper toxicity toxicity. Some of the effects of aging may be associated with excess copper. One manifestation of copper toxicity, cirrhosis of the liver in children (Indian childhood cirrhosis), has been linked to boiling milk in copper cookware. The Merck Manual states recent studies suggest that a genetic defect is associated with this particular cirrhosis. An inherited condition called Wilson's disease causes the body to retain copper, since it is not excreted by the liver into the bile. This disease, if untreated, can lead to brain and liver damage, and bis-choline tetrathiomolybdate is under investigation as a therapy against Wilson's disease. Elevated
Copper in health excess free copper in the brain as the copper can cross the blood-brain barrier directly. Normally, organic copper in food is first processed by the liver which keeps free copper levels under control. If insufficient quantities of copper are ingested, copper reserves in the liver will become depleted and a copper deficiency leading to disease or tissue injury (and in extreme cases, death). Toxicity from copper deficiency can be treated with a balanced diet or supplementation under the supervision of a doctor. On the contrary, like all substances, excess copper intake at levels far above World Health Organization limits can
