homeostatic mechanisms control the amount of Zn
present in tissues, high concentrations of Zn in soil have
not been reported to be associated with human disease.
Certain clays consumed during geophagia might
adsorb Zn from contents of the small intestine and
thus contribute to Zn defi ciency (Halsted
et al
., 1972;
Çavdar
et al
., 1983).
The Zn content of foods varies widely (Table 1).
Reported Zn intake, including children, in several
industrialized countries and India varies widely, from
3.1 (Campbell-Brown
et al
., 1985) to 18.6 mg (Simon-
Hettich
et al
., 2001). A national survey of the United
States found the Zn intakes in Table 2. For comparison,
a 2000-2001 survey of British adults, aged 19-64 years,
