Effects of calcium supplementation, calcium source and lactose on iron absorption in the rat

Fortificación de alimentos con hierro y zinc: pros y contras desde un punto de vista alimenticio y nutricional

“…Para el caso del hierro, el agregado de ácido ascórbico ha demostrado ser efectivo en solucionar en parte este efecto inhibitorio. Sin embargo la vitamina C en medios líquidos, como la leche fluida, se degrada rápidamente a ácido dicetoglucónico, provocando importantes cambios en las características sensoriales del alimento 5,17,[29][30][31][32] .…”

Microencapsulated Ferrous Sulfate to Fortify Cow Milk: Absorption and Distribution in Mice.

“…In the case of calcium, some con tradictions are noted with regard to the degree of its inhibitory effect and the mechanism by which it interferes with the iron absorption. Minotti et al (14) studied the effect of different calcium sources on iron absorption in rats, de monstrating that the chemical form of the calcium source and the physiological conditions of the animals are determinate factors for iron absorption. Deehr et al (15) studied the effect of calcium sources such as calcium citrate malate or milk on iron absorption in postmenopausal women, finding that in the case of milk the inhibitory effect on iron absorption is more important.…”
