Selenium in human health and disease with emphasis on those aspects peculiar to New Zealand
1980
Thomson, Christine D. | Robinson, Marion F.
Recent studies suggest that selenium (Se) may soon be added to the list of essential trace elements. Because New Zealand soil Se content is extremely low (from less than 0.1 to over 4 ppm), human blood and tissue Se in New Zealand is also low by world standards, making the country a natural laboratory for the examination of Se in human health and disease. In residents with a normal diet, deficiency disease has not been found, but a Se-responsive muscular syndrome was described in a surgical patient on hyperalimentation. Groups vulnerable to Se deficiency are: children with metabolic disorders, premature babies, neonates, cancer patients with lowered dietary intake, and patients with either cardiovascular disease, hypertension, and rheumatoid arthritis. Though no minimum Se requirement has been set, New Zealanders might be on the borderline, and effective means of Se supplementation are being studied.
