Trace minerals and atherosclerosis

Abstract

Although there is no evidence for a direct cause-effect relationship between mineral and trace element status and atherosclerosis in humans, many elements exert a strong influence on individual risk factors for cardiovascular disease, such as disorders of blood lipids, blood pressure, coagulation, glucose tolerance, and circulating insulin. Studies in humans and animals have shown that optimal intakes of elements such as sodium, magnesium, calcium, chromium, copper, zinc, and iodine can reduce individual risk factors; some of these studies are consistent with the results of epidemiologic correlations. Influences of local geochemical environment and of dietary practices can result in mineral and trace element imbalances; deficiencies of chromium, iron, copper, zinc, selenium, and iodine are well defined. Detection and correction of such imbalances in populations, through diminishing individual risk factors, might ultimately reduce the incidence of atherosclerotic heart disease.
