Use of ferrous fumarate to fortify foods for infants and young children

NUTRITION REVIEWS, Issue 9 2010
Richard Hurrell
Ferrous fumarate is currently recommended for use in the fortification of foods for infants and young children. This recommendation is based on the compound's good sensory properties and on results from isotope studies in adults that reported similar iron absorption values for ferrous fumarate and ferrous sulphate (relative bioavailability [RBV] of ferrous fumarate, 100). However, later isotope studies conducted on both iron-replete and iron-deficient young children found that iron absorption from ferrous fumarate was only about 30% of that achieved from ferrous sulphate (RBV, 30). The reasons for the differences observed in adults compared with children are unclear but could be related to the following factors: lower iron status in children resulting in greater iron absorption via upregulation from ferrous sulphate but not from ferrous fumarate; reduced gastric acid secretion in children leading to retarded dissolution of ferrous fumarate; or an influence of added ascorbic acid on RBV. Ferrous fumarate-fortified complementary foods have been demonstrated to improve iron status in iron-deficient infants and, more recently, to prevent iron deficiency equally as well as ferrous sulphate in iron-replete infants. However, current evidence indicates that iron-deficient infants and young children may absorb iron from ferrous fumarate less well than iron from ferrous sulfate and that, for equivalent efficacy, complementary foods targeted at such infants and young children should contain more iron in the form of fumarate.

The effect of weekly iron supplementation on anaemia and on iron deficiency among female tea pluckers in Bangladesh

Aim To investigate the effect of weekly iron supplementation on anaemia and iron deficiency among adult, female tea pluckers. Method A randomized double-blind intervention trial was conducted in a tea estate in Bangladesh where a total of 280 women received either weekly iron supplementation (200 mg ferrous fumarate and 200 mg folic acid) for 24 weeks or a matching placebo. Capillary blood samples were drawn at baseline and post-trial to determine haemoglobin, haematocrit and ferritin concentration. Mean corpuscular haemoglobin concentration (MCHC) was calculated using the haemoglobin and haematocrit values. Results The mean haemoglobin concentration in the supplemented group increased by 5.52 g L,1 over the study period, on average, while ferritin values decreased by 0.33 ,g L,1. The control group showed a decrease in both mean haemoglobin (,0.24 g L,1) and ferritin (,5.32 ,g L,1). Those individuals in the supplemented group with the lowest pretrial haemoglobin and ferritin values experienced the greatest improvements post-trial, whereas nonanaemic individuals showed a decrease in both haemoglobin and ferritin concentrations. A total of 62.2% of women in the supplemented group reported feeling better and more energetic compared to 51.1% in the placebo group; 14.4% of the supplemented group and 22.7% of the control group complained about side-effects. Conclusion Weekly iron supplementation was logistically simpler and cheaper than daily supplementation but would have to be continued on a longer term basis in order to combat both anaemia and iron deficiency.
