Abstract
Few studies have evaluated iron absorption in small children after the first year of life. Our objectives were to examine the relations among iron intake, iron absorption, and iron status in a group of healthy children. We studied 28 children, ages 12 to 48 mo, after a 7-d home adaptation to a diet representative of their usual daily mineral intake. A multi-tracer stable isotope study was performed to assess iron absorption both from a meal (^sup 58^Fe) and from a reference iron dose (^sup 57^Fe) given with ascorbic acid without a meal. Iron intake was 6.9 ± 2.4 mg, approximately the 35th percentile of typical U.S. intakes. Absorption of ^sup 58^Fe was related to serum ferritin ...
