護理師指導孕婦預防缺鐵性貧血，下列何種食物組合能達到最佳吸收效果？
A nurse is educating a pregnant client about iron-deficiency anemia prevention. Which food pairing should the nurse recommend for optimal absorption?
- ASpinach salad with a hard-boiled egg菠菜沙拉配水煮蛋
- BLentil soup with a side of yogurt扁豆湯配優格
- CGrilled steak with a glass of milk烤牛排配一杯牛奶
- DFortified cereal with a glass of orange juice✓ 正解強化穀物配一杯柳橙汁
缺鐵性貧血的預防重點在於提升鐵質的生物利用率。膳食中的鐵分為血基質鐵（Heme iron）與非血基質鐵（Non-heme iron）。維生素 C 具有還原作用，能將腸道內的三價鐵（Fe3+）還原為較易吸收的二價鐵（Fe2+），創造酸性環境以利吸收。相反地，鈣質、單寧酸（茶/咖啡）與植酸會與鐵結合形成不溶性複合物，抑制吸收。
Prevention of iron deficiency anemia focuses on enhancing the bioavailability of dietary iron. Dietary iron is classified as heme iron and non-heme iron. Vitamin C, which is a reducing agent, can convert ferric iron (Fe3+) in the intestinal lumen to the more easily absorbed ferrous iron (Fe2+) and create an acidic environment favorable to absorption. Conversely, calcium, tannins (in tea/coffee), and phytates bind to iron to form insoluble complexes that inhibit absorption.
