Previous studies suggest that vegetarians may not receive enough zinc
 in their diets and the zinc requirement is especially important during
 pregnancy. Twenty-three women were monitored: twelve vegetarians who
 were pregnant, six nonvegetarians who were pregnant, and five
 vegetarians who were not pregnant. Is there any evidence that
 pregnant vegetarians tend to have lower zinc levels than pregnant
 nonvegetarians?
