Scientists have claimed people should remove old copper pipes from their homes, or else install special filters, because the metal has been shown to build up in your body and cause serious health problems.
Tiny traces of copper from pipes mix with tap water and are then consumed. Over a long period of time this leads to a build-up of copper in your body, which in turn leads to Alzheimer's disease, heart disease and diabetes because your body cannot process the metal.
People over 50 should also avoid vitamin and mineral pills that contain cooper and iron. They should also donate blood regularly to reduce iron levels.
