ABSTRACT. Iron and zinc are currently the trace minerals of greatest concern when considering the nutritional value of vegetarian diets. With elimination of meat and increased intake of phytatecontaining legumes and whole grains, the absorption of both iron and zinc is lower with vegetarian than with nonvegetarian, diets.

Zinc is a critical trace mineral involved in the activity of over 100 enzymes and supports protein synthesis, tissue growth, DNA synthesis, and cell division. Despite its importance, the body does not have a specialized zinc storage mechanism and must be obtained through the diet or supplementation to ensure adequate levels are maintained.

Identified as an element in 1746, but known to the Greeks and Romans before 20BC. The name is derived from the German, 'zinc', which may in turn be derived from the Persian word 'sing', meaning stone. A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell.

· Sphalerite (zinc sulfide) is the primary ore mineral from which most of the world's zinc is produced, but a number of other minerals that do not contain sulfide contain zinc as a major component. Much of the early zinc production was from nonsulfide deposits; however, as these resources were exhausted, production shifted to sulfide deposits.
