A new report published in the journal Chemical Research in Toxicology suggests individuals over the age of 50 consider taking measures to avoid potentially dangerous copper and iron toxicity.

Previous studies have linked high levels of these essential nutrients to Alzheimer’s disease, heart disease, and other age-related disorders.

"This story of copper and iron toxicity, which I think is reaching the level of public health significance, is virtually unknown to the general medical community, to say nothing of complete unawareness of the public," said researcher George Brewer.

Researchers say that although high levels of both copper and iron are beneficial for the reproductive health of younger individuals, high levels after age 50 could damage cells and contribute to a variety of age-related diseases.

"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," said Brewer.

Among the ways the report suggests to avoid toxic levels of these nutrients are lowering meat intake, avoiding drinking water from copper pipes, donating blood regularly to reduce iron levels and taking zinc supplements to lower copper levels.
