Scientists have long recognized the dangers of cadmium (Cd) exposure to the human body. This heavy metal is emerging as a major cause of vascular disorders, common cancers, osteoporosis, and kidney disease, and can also cause damage to the body’s reproductive and neurological systems. While tobacco smoke can be a significant source of exposure for smokers, the primary source of cadmium exposure for nonsmokers is through consumption of contaminated plant-based foods. A survey of all previous pertinent research (meta-analysis), appearing recently in the British Journal of Nutrition, concluded that organically grown foods are on average 48 percent lower in Cd than conventionally grown foods. Now, in an invited commentary appearing in the same journal, Saint Luke’s Mid America Heart Institute cardiovascular research scientist James J. DiNicolantonio, Pharm.D., and Mark F. McCarty, B.A., place this finding in the context of the growing epidemiology linking Cd exposure to adverse health outcomes, and conclude that consistent consumption of organic foods over a lifetime could be expected to favorably influence health and mortality risk.
