Serum Magnesium in Greenland Eskimos

Abstract
Serum Mg in Greenland Eskimos living in Greenland is significantly higher (P < 0.001) than in Greenlanders and Danes living in Denmark. Danes living in Greenland show intermediate values. The higher serum Mg may be due to a high intake of nutrients from fish and sea mammals. A more complete intestinal absorption of Mg caused by a low dietary Ca should also be considered. The high serum Mg may contribute to the rare occurrence of urinary calculi in Greenlanders.
