The aim of this study is to determine the effect of proteins from cereals and legumes on heme iron (Fe) absorption. The absorption of heme Fe without its native globin was measured. Thirty adult females participated in two experimental studies (15 per study). Study I focused on the effects of cereal proteins (zein, gliadin and glutelin) and study II on the effects of legume proteins (soy, pea and lentil) on heme Fe absorption. When heme was given alone (as a control), study I and II yielded 6.2% and 11.0% heme absorption (p > 0.05). In study I, heme Fe absorption was 7.2%, 7.5% and 5.9% when zein, gliadin and glutelin were added, respectively. From this, it was concluded that cereal proteins did not affect heme Fe absorption. In study II, heme Fe absorption was 7.3%, 8.1% and 9.1% with the addition of soy, pea and lentil proteins, respectively. Only soy proteins decreased heme Fe absorption (p < 0.05). These results suggest that with the exception of soy proteins, which decreased absorption, proteins derived from cereals and legumes do not affect heme Fe absorption.
本研究的目的是确定谷物和豆类蛋白质对血红素铁（Fe）吸收的影响。测定了去除天然球蛋白的血红素铁的吸收情况。30名成年女性参与了两项实验研究（每项研究15人）。研究I聚焦于谷物蛋白（玉米醇溶蛋白、麦醇溶蛋白和谷蛋白）的影响，研究II聚焦于豆类蛋白（大豆、豌豆和小扁豆）对血红素铁吸收的影响。当单独给予血红素（作为对照）时，研究I和II的血红素吸收率分别为6.2%和11.0%（p>0.05）。在研究I中，添加玉米醇溶蛋白、麦醇溶蛋白和谷蛋白时，血红素铁吸收率分别为7.2%、7.5%和5.9%。由此得出结论，谷物蛋白不影响血红素铁的吸收。在研究II中，添加大豆、豌豆和小扁豆蛋白时，血红素铁吸收率分别为7.3%、8.1%和9.1%。只有大豆蛋白降低了血红素铁的吸收（p<0.05）。这些结果表明，除了降低吸收率的大豆蛋白外，谷物和豆类来源的蛋白质不影响血红素铁的吸收。
