Laboratory rats were fed several types of carbohydrates incorporated into iron-deficient diets. The lowest active transport of 59Fe++ across the intestinal wall as well as the lowest intestinal accumulation of radioiron occurred in rats fed either dextrin or fructose, while rats fed cornstarch, sucrose, or sucrose plus lactose exhibited the highest active transport and the highest accumulation of radioiron in the intestinal tissue. Animals which received dextrin as the dietary carbohydrate also maintained the highest hematocrit and hemoglobin levels during the iron depletion period.
给实验大鼠喂食添加了几种碳水化合物的缺铁饮食。喂食糊精或果糖的大鼠，其59Fe++跨肠壁的主动转运最低，肠道放射性铁的积累也最少，而喂食玉米淀粉、蔗糖或蔗糖加乳糖的大鼠，其肠道组织中的主动转运最高，放射性铁的积累也最多。在缺铁期间，以糊精作为膳食碳水化合物的动物还保持了最高的血细胞比容和血红蛋白水平。
