The report, by Dr. George Brewer at the University of Michigan Medical School, is in the American Chemical Society (ACS) journal, Chemical Research in Toxicology and it is a review of toxicity research.  Dr. Brewer indicates that copper and iron toxicities are so severe in the population that they are a public health problem.

Unfortunately, the body stores excess metals, and they build up as we age.  After 50, these toxic metals can contribute to Alzheimer's and other neurodegenerative diseases, arteriosclerosis, diabetes, and several other diseases.  One study found that those in the top fifth in copper intake lost cognition at three times the normal rate, if they were also eating a relatively high fat diet. 

Copper is found in drinking water, especially if it comes from copper pipes, but Dr. Brewer indicates that even one-tenth the amount of copper that is allowed in human drinking water by the Environmental Protection Agency induced cognitive decline in animal models. 

"It seems clear that large segments of the population are at risk for toxicities from free copper and free iron, and to me, it seems clear that preventive steps should begin now," Dr. Brewer said.  And he indicates that people over the age of 50 should avoid vitamins and minerals that contain copper and iron, lower their meat intake, avoid drinking water from copper pipes, and take zinc supplements to lower copper levels.  Additionally, he advises those who are able to give blood regularly, as that will reduce iron levels.

Time to overhaul older homes & biz sites alone

Time for PVC piping & fiber optic networks & Witricity: electric power via wireless modes.

Esp the NE Central Eastern US area alone.

More jobs alone.

More growth.

& yes copper pipes are worth $$$$$$$ to anyone.

Maybe some got Alhz due to home environments or workplace.

More jobs to clean up worksites alone.
