title: Mineral insufficiency and cancer.
abstract: There are excellent theoretical reasons why the mineral nutrients selenium, manganese, copper and zinc, known as the antioxidant minerals, may be involved in the prevention of cancer aetiogenesis. The biochemistry is discussed of the part played by the antioxidant minerals, in the wider context of the other dietary antioxidants vitamins A, E and C, and beta carotene, in preventing tissue damage caused by activated metabolites of oxygen. The likely part played by these oxygen metabolites is described and a detailed review given of the evidence that suggests a role for antioxidant minerals, notably selenium, in preventing carcinogenesis in a range of animal models. There follows a summary of the emerging epidemiological evidence that suggests clearly that low selenium intake is a risk factor in the aetiology of human cancer.
