Infant formula iron dialysability related to other nutrients

The dialysable iron in relation to total iron, to protein sources, to calcium, magnesium, copper, zinc, and vitamin C of 17 infant formulas, from four different multinational companies were analyzed. Total iron, calcium, magnesium, copper, and zinc were determined by atomic absorption spectrophotome...

Total iron, calcium, magnesium, copper, and zinc were determined by atomic absorption spectrophotometry. the dialysable iron was determined. the considered vitamin C concentration was that declared on the labels. There was no significant statistical relationship between total iron and dialysable iron (P = 0.54, r = 0.09) when considered separately. When analyzed considering protein sources, this relationship was shown to be inversely proportional to protein hydrolysate (P = 0.03, r = -0.72), and soy protein (P = 0.02, r = -0.93). the percentage of dialysable iron was significantly greater from the protein hydrolysate (P < 0.01). the dialysable iron showed a negative correlation with calcium (P < 0.05, r = -0.61). in conclusion, the infant formulas whose protein sources are casein and casein plus whey protein should present Ca:Fe and Fe:vitamin C ratios that allow considerable iron dialysability.
