Bioavailability of iron from a traditional Tunisian meal with chickpeas fed to healthy rats.
The influence of a diet of couscous with chickpeas, a traditional Tunisian meal, or one providing iron as ferrous sulfate, on the utilization of 59Fe was evaluated in studies with rats. The iron content of the couscous and chickpea preparation was 30 mg/kg dry weight. There was no difference in the relative absorption of iron from ferrous sulfate or couscous with chickpeas, suggesting that iron from this preparation may be a good dietary source of nonheme iron for rats. Couscous and chickpeas consumption in Tunisia are estimated at 13.3 and 3.2 kg per capita/year, respectively. Our results in rats indicate that these foods could contribute a large proportion of an individual's iron requirement. We conclude that the plant foods, especially the chickpeas, can be excellent sources of dietary-available iron.
