Question: what are the nutritional differences between human breast milk and infant formula?
Answer: The iron content of human milk is low: 0.5 mg/L compared with 10 to 12 mg/L in supplemented cow-milk formulas. The absorption rate, however, is considerably higher. Breastfed infants absorb up to 50 percent of consumed iron, compared with a 7- to 12-percent absorption rate for formula-fed infants (Fomon et al., 1993).
