Zinc and iron contents and their bioaccessibility in cereals and pulses consumed in India

Evaluation of the content and bioaccessibility of iron, zinc, calcium and magnesium from groats, rice, leguminous grains and nuts

“…The release for Mg also fell within a wide range of values from 2.2% (barley groats) to 49.6% (shelled peas). Hemalatha et al (2007a) found lower biaccessibility of iron and zinc from cereals (Fe: 4.13-8.05%; Zn: 5.5-21.4%) and pulses (Fe: 1.77-10.2%; Zn: 27-56%) consumed in India in compared to products analysed in this experiment. In this study the release of minerals (expressed as the percentage of total content) varied considerably depending on the type of mineral and a particular food matrix.…”

“…The study of Karamac et al (2007) showed that tannins present in buckwheat groats are strong chelators of Cu, Fe and Zn. Hemalatha et al (2007a) showed that tannin in cereals and pulses consumed in India did not have any significant influence on zinc and iron biaccessibility. Moreover, mentioned authors found significant negative correlation between phytate content and zinc biaccessibility in pulses, while phytic acid content had a negative influence on iron release from cereals.…”

Nutritional Composition of Five Varieties of Pap Commonly Consumed in Maroua (Far- North, Cameroon)

“…The four most important micronutrients in human nutrition are vitamin A, iron, and iodine and zinc [Hemalatha et al, 2007]. Iron deficiency is the most widespread nutritional deficiency [Hemalatha et al, 2007], afflicting over half of the world's population in 2000, and increasing particularly among poor women in developing countries [Welch & Graham, 2005].…”

Biofortification in Cereals:Progress and Prospects

“…has also been observed which affects bioavailability of grain Fe and Zn 36 . Bioaccessibility of Fe and Zn from sorghum was reported to be very low at 4.13% and 5.51% respectively 37 . At International Crops Research Institute for the SemiArid Tropics (ICRISAT), a total of 2267 core germplasm accessions were screened and promising donors were identified with Fe ranging from 20 to 70 ppm and Zn from 13 to 47 ppm under the HarvestPlus programme.…”
