Copper in tap water linked to Alzheimer’s
Copper in tap water linked to Alzheimer’s disease.
Dr George Brewer, lead researcher at the American Chemical Society(1) explains that metals are essential to the body’s functions; they assist the transportation of oxygen through the body and specifically, ‘copper plays an important role in the communication between nerve cells, bone growth and hormone secretion, so it is important to get enough of the metal in your diet’(2).
This is easy to achieve, as copper is naturally present in many foods including fruits and vegetables, nuts, red meat and shellfish.
Copper is also included in many vitamin and mineral supplements and is present in tap water in homes with copper pipes. Copper in foods seems to be non-problematic, but researchers warn that “inorganic copper in drinking water and in supplements is handled differently than food copper, and is therefore more toxic”.(1)
Scientists have found that even very small traces of copper in drinking water — one-tenth that of US legally permitted levels — “greatly enhanced an Alzheimer’s-like disease in an animal model”. (1)
According to a study in the Proceedings of the National Academy of Sciences (PNAS), researchers found that ‘copper prevents the clearance of beta-amyloid’(3). When this protein accumulates in the brain, it forms plaques associated with Alzheimer’s disease.
Dr Brewer warns that the Alzheimer’s risks associated with copper are particularly of concern to people aged 50 and over, when the body can no longer efficiently process the metal.
A common-sense approach would be to continue to consume naturally-occurring, food-based copper through a balanced diet, but avoid mineral supplements containing copper and ensure that your drinking water does not contain copper. You can do this simply and cost-effectively by installing a Pure H2O USA. Quatreau Tap with our patented RODI system
Our water purifiers remove copper as well as other metals, trace elements, bacteria, hormones and pesticides and guarantee safe, healthy drinking water that will not compromise your health. Quatreau Pure Water also tastes delicious and is environmentally sustainable.
