目的 :比较在稀释酸中可转化的焦磷酸铁和延胡索酸亚铁的铁生物利用度 ,同时评估抗坏血酸对婴儿延胡索酸亚铁的铁生物利用度的影响。实验设计 :在服用标记食物 1 4天后 ,用掺入红细胞中稳定同位素铁来测量铁的生物利用度 ,标记食物为 2 5g干小麦黄豆婴儿谷类食物 ,1 0 0 g水和 OBJECTIVE: To compare the bioavailability of iron that can be converted to iron pyrophosphate and ferrous fumarate in dilute acids, and to assess the effect of ascorbic acid on iron bioavailability of infant fumaric acid ferrous. Experimental Design: The bioavailability of iron was measured by incorporation of stable isotope iron in erythrocytes 14 days after taking the labeled food, labeling the food as 25 g dry whey soy baby cereal, 100 g water and
