Researchers believe copper combined with cholesterol may prevent the brain removing a protein which produces the brain-clogging plaques associated with Alzheimer’s.
The tap water link emerged from a study of rabbits fed a high cholesterol diet.
It has long been known that rabbits fed a cholesterol-rich diet develop many of the features of Alzheimer’s, leading researchers to use them as a model for studying the disease.
But two US scientists noticed that cholesterol-fed rabbits given distilled water to drink developed fewer amyloid beta plaques than those drinking tap water.
Further investigation revealed significant amounts of copper in the tap water of many laboratories housing rabbits used in Alzheimer’s research.
To test the copper connection, the scientists added trace amounts of the metal to distilled water given to a group of cholesterol-fed rabbits.
Rabbits receiving the copper additive for 10 weeks developed significantly more plaques and precursors called senile plaque-like structures (SPs) than cholesterol-fed rabbits that drank “pure” distilled water.
The copper-dosed rabbits were also less able to learn a difficult conditioning task than animals not receiving the supplement.
The study was reported in the journal Proceedings of the National Academy of Sciences.
The researchers concluded: “Although we can only speculate about how the effects of copper consumption in cholesterol-fed rabbits relate to those in humans, it is of note that the levels of copper in the cholesterol-fed rabbit drinking water that induced amyloid beta and SP-like structures are well below those considered safe for humans.”

We’re delighted to announce that as well as supplying domestic and commercial settings with our multi-function taps and water purifiers, we now serve the marine market.
Maintaining ample quantities of drinking water of sufficient quality poses several problems to the boat owner, most -significantly finding storage space for plastic bottled water, or risking the effects of stomach-churning impurities present in a fresh water tank.
The Quatreau SmartTap solves both problems and delivers additional benefits. The compact drinks station dispenses chilled, sparkling, boiling and / or ambient water at the touch of a button, which means no trips to the supermarket for bottled or sparkling water, no lost storage space for all those plastic bottles, and no saucepan required on board for hot drinks or blanching vegetables.
MotorBoat & Yachting features the Quatreau SmartTap in their November issue, commenting “Really convenient and will put a stop to the familiar bottled water avalanche every time you open the fridge after a rough trip”
Recently featured in Boating Business, innovator and company M.D. Roger Wiltshire advises that the Quatreau SmartTap is suitable for retrofit or new builds and is available in a range of finishes including brushed or polished solid 316 stainless steel, with left and right hand options.
The recently refitted Mia Elise II*, a 197 ft custom motor yacht with impressive leisure and entertainment facilities currently available for charter, benefits from the Quatreau SmartTap. Accommodating 12 guests and 15 crew, the yacht’s water requirements are assured thanks to the high volumes delivered by our Quatreau SmartTap, with purity guaranteed by the addition of our RODI water purifier.
The Quatreau SmartTap was also specified on performance cruiser Elfje. As Yachting World reports, energy efficiency and sustainability were top of owner Wendy Schmidt’s priorities for her custom built 172ft ketch. Quatreau SmartTap ensures the lowest possible energy consumption and highest performing thermal insulation, its solid 316 stainless steel build ensuring strength and longevity with low environmental impact.
The SmartTap’s standard in-line filtration removes impurities from the vessel’s water tank, but for extra peace of mind specifiers and vessel owners will undoubtedly opt for the optional under-counter water purifier which delivers up to 99.99% pure water, guaranteed free from micro-organisms and every other health-compromising contaminant or impurity. This purifier is the only system on the market to carry EPA certification for the removal of micro-organisms, and the Quatreau SmartTap is the only one of its kind manufactured in the UK, which guarantees excellent build quality compared to imported systems.
