The influence of dietary pectin on iron absorption and retention was studied in rats. Basal diet with low and normal iron levels were fed with and without addition of 2% citrus pectin. After 40 days rats were fasted for 24 hours and were given 59Fe in dilute HCl with or without 2% pectin by gavage. Whole-body counting techniques were employed to monitor 59Fe absorption and turnover. Rats maintained on low iron diet absorbed and retained a much higher proportion of 59Fe than rats maintained on normal level of iron. Dietary pectin at the level fed in this study had no influence on iron uptake and/or turnover in rats.
在大鼠中研究了膳食果胶对铁吸收和潴留的影响。给低铁水平和正常铁水平的基础饮食分别添加和不添加2%柑橘果胶进行喂食。40天后，大鼠禁食24小时，然后通过灌胃给予含或不含2%果胶的稀盐酸中的59Fe。采用全身计数技术监测59Fe的吸收和周转。维持低铁饮食的大鼠比维持正常铁水平的大鼠吸收和潴留59Fe的比例要高得多。本研究中所喂食水平的膳食果胶对大鼠的铁摄取和/或周转没有影响。
