  • Title: Nutritional factors in relation to heavy metal toxicants.
    Author: Levander OA.
    Journal: Fed Proc; 1977 Apr; 36(5):1683-7. PubMed ID: 191297.
    Abstract:
    An increased environmental exposure to various toxic heavy metals such as lead, cadmium, or mercury seems to be a fact of 20th-century life. But relatively little attention has been paid to the possible implications of sucy exposure for the nutritional status of humans and animals. This review summarizes the information available concerning the effect of various nutritional factors in resistance to metal toxicants and the effect of heavy metal toxicity on nutritional status. In particular, the following questions are considered: 1) Are there any examples of heavy metal toxicity that are potentiated by a nutritional deficiency? 2) Is there any evidence that nutritional deficiency can be caused by heavy metal toxicity? 3) Is there any proof that heavy metal toxicity can be decreased by an excess intake of nutrients: 4) Is there any proof that heavy metal toxicity can be increased by an excess intake of nutrients? The discussion is focused primarily on studies with animal models but, wherever possible, implications for human health are pointed out.
