Our objective was to compare the capacities of biofortified and standard black beans (Phaseolus vulgaris L.) to deliver iron (Fe) for hemoglobin (Hb) synthesis. Two lines of black beans, one standard and the other biofortified (high) in Fe (71 and 106 microg Fe/g, respectively), were used. Maize-based diets containing the beans were formulated to meet the nutrient requirements for swine except for Fe (Fe concentrations in the 2 diets were 42.9 +/- 1.2 and 54.6 +/- 0.9 mg/kg). At birth, pigs…

Polyphenolic compounds appear to limit the nutritional benefit of biofortified higher iron black bean (Phaseolus vulgaris L.)
Fe-biofortified beans remain a promising vehicle for increasing intakes of bioavailable-Fe in human populations that consume high levels of these beans as a dietary staple, and the bean polyphenol profile must be further evaluated and modified if possible in order to improve the nutritional quality of higher-Fe beans.
Biofortified red mottled beans (Phaseolus vulgaris L.) in a maize and bean diet provide more bioavailable iron than standard red mottled beans: Studies in poultry (Gallus gallus) and an in vitro digestion/Caco-2 model
In-vitro analysis showed lower iron bioavailability in cells exposed to standard ("Low Fe") bean based diet, which justifies further work on the large-seeded Andean beans which are the staple of a large-region of Africa where iron-deficiency anemia is a primary cause of infant death and poor health status.

High bioavailablilty iron maize (Zea mays L.) developed through molecular breeding provides more absorbable iron in vitro (Caco-2 model) and in vivo (Gallus gallus)
Maize shows promise for Fe biofortification; therefore, human trials should be conducted to determine the efficacy of consuming the high bioavailable Fe maize to reduce Fe deficiency.
Using the domestic chicken (Gallus gallus) as an in vivo model for iron bioavailability.
The broiler chicken is assessed as a model for hemoglobin (Hb) maintenance studies and a unique duodenal loop technique is presented for direct measurement of intestinal Fe absorption to indicate that this model exhibits the appropriate responses to Fe deficiency.

Common bean (Phaseolus vulgaris L.) is a staple food of smallholder farmers and poor urban consumers in Latin America and eastern-southern Africa among whom iron deficiency is frequent, and breeding progress has been slow, likely due in part to homeostatic mechanisms whereby organisms moderate iron and zinc uptake.
Iron bioavailability of four iron sources used to fortify infant cereals, using anemic weaning pigs as a model
Ferrous fumarate and MDFP were equally as bioavailable as the reference salt, and were used significantly better than EI in piglets, contributing to extend the evidence-based results for recommending the most suitable fortificant for infant cereals.
Iron bioavailability of four iron sources used to fortify infant cereals, using anemic weaning pigs as a model.
Iron (Fe) deficiency anemia in young children is a global health concern which can be reduced by Fe fortification of foods. Cereal is often one of the first foods given to infants, providing adequate
Iron Biofortified Carioca Bean (Phaseolus vulgaris L.)—Based Brazilian Diet Delivers More Absorbable Iron and Affects the Gut Microbiota In Vivo (Gallus gallus)
The results demonstrate that the Fe-biofortified carioca bean variety was able to moderately improve Fe status and to positively affect the intestinal functionality and bacterial populations.
Demonstrating a Nutritional Advantage to the Fast-Cooking Dry Bean (Phaseolus vulgaris L.).
It is suggested that fast-cooking bean varieties have improved nutritive value through greater nutrient retention and improved iron bioavailability in faster cooking entries in the same market class.


Genetic selection for enhanced bioavailable levels of iron in bean (Phaseolus vulgaris L.) seeds.
The bioavailability of Fe from 24 select genotypes of bean (Phaseolus vulgaris L.) seeds containing a range of concentrations of Fe, myo-inositol pentaphosphate plus phytic acid, and tannin seed concentrations was studied using a rat model, finding no significant correlation between the Fe concentration in different bean genotypes and Fe bioavailability to rats attributable to variations in IP5+IP6 or tannins.
Supplemental dietary inulin affects the bioavailability of iron in corn and soybean meal to young pigs.
It is concluded that supplementing 4% inulin improved utilization of intrinsic iron in the corn and soybean meal diet by young pigs, and this benefit was associated with soluble Fe and sulfide concentrations but not pH or phytase activity in the digesta.
Iron-biofortified rice improves the iron stores of nonanemic Filipino women.
Consumption of biofortified rice, without any other changes in diet, is efficacious in improving iron stores of women with iron-poor diets in the developing world.
Effects of dietary iron supplementation on growth performance, hematological status, and whole-body mineral concentrations of nursery pigs.
Results suggest that Fe contributed by feed ingredients was not sufficient to maintain indices of Fe status and the lessening of a pig's Fe stores during this rapid growth period may result in the occurrence of anemia during the subsequent grower and finisher periods.
Biofortification of staple food crops.
Scientific evidence shows biofortification as being important in the armamentarium for controlling micronutrient deficiencies and the challenge is to get producers and consumers to accept biofortified crops and increase their intake of the target nutrients.
Food-based strategies to meet the challenges of micronutrient malnutrition in the developing world
Linking community development policies to national programmes for the alleviation of hunger and malnutrition, with an emphasis on increasing the variety of foods consumed, is probably the best strategy for improving micronutrient malnutrition sustainably.
Impact of Feeding High-Iron Rice on Plasma Iron, Hemoglobin and Red Blood Cell Variables of Early-Weaned Piglets
Modifications regarding study design, study duration and subject’s growth rate are recommended to increase the possibility of detecting changes in the iron status triggered by diets having small differences in dietary iron.
Nutrition and health implications of dry beans: a review.
The nutrient composition of dry beans makes them ideally suited to meet two major dietary recommendations for good health--increased intake of starches and complex carbohydrates and decreased
Effect of ascorbic acid intake on nonheme-iron absorption from a complete diet.
The facilitating effect of vitamin C on iron absorption from a complete diet is far less pronounced than that from single meals, which may explain why several prior studies did not show a significant effect on iron status of prolonged supplementation with vitamin C.
