Calcium, magnesium, sodium, potassium and iron content of infant formulas and estimated daily intakes

The calcium, magnesium, sodium, potassium and iron content of a total of 22 different infant formulas marketed in Spain were measured by atomic spectrometry, and the mineral intake of infants fed exclusively with these formulas was estimated. The contents (mg/100kJ) are in the following ranges: Ca, 14-24; Mg, 1.1-2.8; Na, 5.6-9.8; K, 19-35; Fe, 0.02-0.50. These values coincide with those recommended by the Codex and European Society for Paediatric Gastroenterology and Nutrition (ESPGAN), and do not exceed the limits established by the European Union (EU). The mean values and ranges of estimated intakes for each formula type and period of infancy (0-1, 1-2, 2-3, 3-4 and 4-5 months) expressed…
