Abstract
The efficacy of intake of iron fortified, wholemeal rye bread on iron status of young women with low iron stores was evaluated in a 5 month single-blind intervention study. Two parallel groups of women (20–38 y) were given 144 g of rye bread/d either fortified with 6 mg iron as ferrous fumarate/100 g bread (i.e. 8.6 mg iron/d) (n=21) or unfortified (n=22) in addition to their normal diet. Blood samples were taken at 0, 2.5 and 5 months. Serum ferritin in the control group changed significantly from 0 mo: 24.6 [21.0–28.8] μg/l to 5 mo: 20.2 [17.5–23.3] μg/l. There was no change in serum ferritin in subjects given iron fortified bread. Haemoglobin was unchanged in the control group, 124±8 g/l. In the fortification group, there was a non-significant increase from 0 to 5 months: 124±6 and 126±8 g/l. Intake of fortified wholemeal rye bread resulted in a stabilisation of iron stores of young women with poor iron status which were otherwise reduced by intake of the unfortified control bread.
