Macro- and trace-mineral intakes of exclusively breast-fed infants

Am J Clin Nutr. 1987 Jan;45(1):42-8. doi: 10.1093/ajcn/45.1.42.


Intakes of calcium, phosphorus, magnesium, zinc, sodium, potassium, iron, and copper of 45 exclusively breast-fed infants were determined during the first 4 mo of life. Direct 24-h measurements of milk intake and mineral contents of human milk were used to estimate mineral intakes. Daily intakes of Ca, P, Zn, K, Na, Fe, and Cu decreased significantly over the study period while the intake of Mg increased. With the exception of Mg, mineral intakes on a weight basis displayed significant quadratic trends over the 4 mo. In spite of seemingly low-mineral intakes, growth progressed satisfactorily.
