Abstract: Trace metals are important for normal growth and development of infants. Intakes may be especially necessary for pre-term and low birthweight infants who may exhibit lower nutrient stores at birth and are therefore vulnerable to trace element deficiency. Average daily intakes of zinc, copper, manganese and selenium of 37 pre-term, 24 full-term low birthweight, and 38 full-term control infants were calculated; 24-hour recall and 3 day dietary records were collected from mothers for infants at 1 and 3, and 6 and 12 months of age, respectively. Zinc intakes in all infants up to 6 months old were low by Canadian Dietary Standards (CDS). All infants met CDS levels for copper at all ages, but were deficient after 1 month of age in relation to WHO recommendations. Manganese intakes were adequate, but selenium intakes were low in all 3 groups. However, since mixed feeding is usually practiced by 12 months, trace metal intakes met dietary recommendations after the first year of infancy.
