Iron absorption from the meal that included apple juice was significantly correlated with serum ferritin concentration ( P =. Median iron absorption from the meal ingested with orange juice was 7.78% (9.80% ± 6.66% P =. Results Median iron absorption from the meal ingested with apple juice was 7.17% (mean ± SD, 9.48% ± 9.68%). Main Outcome Measures Iron absorption measured by established stable isotope methods. Intervention Identical meals served with orange juice and apple juice were given on consecutive days, in a balanced randomized design. Patients A total of 25 healthy children, 3 to 6 years of age, were recruited, of whom 21 (11 male and 10 female) completed the study. Setting Nutrition research institute in a major metropolitan medical center.
Iron absorption was measured from red blood cell incorporation of the iron stable isotopes 14 days later. The meals were labeled with iron-57 on one day and iron-58 on the other. Objective To measure iron absorption in children from meals containing apple juice or orange juice so as to determine if iron absorption will be greater with orange juice because of its higher ascorbic acid content than apple juice, a noncitrus fruit juice that US children reportedly prefer.ĭesign On 2 successive days, children consumed identical meals that included apple juice on one day and orange juice on the other, in random order.
