A. Gleerup et al., DURATION OF THE INHIBITORY EFFECT OF CALCIUM ON NONHEME IRON-ABSORPTION IN MAN, European journal of clinical nutrition, 47(12), 1993, pp. 875-879
We investigated the duration of the inhibitory effect of calcium from
milk and cheese (340 mg) in a breakfast meal on non-haem iron absorpti
on from a hamburger meal eaten 2 or 4 h after the breakfast. The effec
t of calcium on iron absorption was studied in 21 human subjects by us
ing paired observations and a dual-radioisotope method (Fe-55 and Fe-5
9). No duration effect of calcium on iron absorption was observed in t
his study. The present findings offer an opportunity for theoretical i
mprovement of iron nutrition by a redistribution of the daily intake o
f calcium to the meals with a minor iron content, i.e. breakfast and t
he evening meal.
