Abstract

A study was made in diets offered to a group of pre-school children,whose mean age was 67 months and remained the whole day in three day carecenters from Juiz de Fora, M.G., Brazil. For sampling, the duplicate portiontechnique was used, and the diets were collected and analyzed separately eachday in the 3 nurseries. Instrumental neutron activation analysis was appliedto the determination of 16 elements. The daily dietary intake values werecompared to the RDA (children 4–6 years old). Based on this reference,Ca, Fe, Se and Zn were found to be deficient, Mg and Mn were comparable tothe RDA and the Cl and Na concentrations were higher compared to their RDA.For the other elements measured, there are no RDA's for children.
