[Metabolic balance of zinc in infants and children].

The zinc intake chemically measured oscillated in the broad limits from 0,2 to 17,1 mg/d according to the age and to the manner of feeding; the highly positive zinc retentions were obtained only in infants with high intake of this element. Zinc in the diet of infants in some part derived from water.
