New research by French scientists has revealed important links between the levels of three metals – magnesium, copper and zinc – in the body and the risk of developing cancer and heart disease.
Research carried out by Dr Nathalie Leone of the Lille Pasteur Institute showed that high serum levels of magnesium were linked to a 40% lower risk of mortality (from all causes), and a similar reduction for cardiovascular deaths. By contrast, high serum levels of copper and low levels of zinc were associated with increased risk of death from all causes.
Dr Leone’s research was published recently in the journal Epidemiology. In her paper she comments on the need to research further the apparent interactions between magnesium, copper and zinc. She writes: “Decreased zinc and either increased copper or decreased magnesium might synergistically enhance oxidative damage and inflammatory response.” Oxidative damage and inflammation are at the root of almost every disease, including cancer and cardiovascular disease, as well as premature ageing.
The research has attracted the interest of nutritionists since recent dietary surveys have shown that large parts of the adult population are failing to achieve the recommended daily allowance (RDA) for magnesium.
