This study was undertaken to make comparative study on the effect of kinds(Cellulose, Agar) & contents(2.5%, 5%, 10%) of the dietary fiber with the normal Fe intakes(66ppm) on the Fe metabolism in rats during the four weeks of growth period Sixty-four male rats of wistar strain weighing $76.2pm2.5g$ were randomly designed to one of the 8 groups. All the groups received basal diet with 9% casein and no acorbic acid. The results obtained are summarized following; 1) Feed consumption per 100g b.w. & body weight gain in normal Fe intake groups tended to be higher than Fe deficient groups, but, there was no significant difference among the 8 groups. However, body weight gain & feed consumption in cellulose sloops were significantly higher than agar groups in all the levels tested.(P<0.01). 2) Fecal Fe excretion per 100g b.w. increased significantly with increase in dietary fiber during the four weeks, but there was no significant increase in fecal weight per l00g b.w. & urinary Fe excretion. 3) Hemoglobin concentration & hematocrit decreased slightly in SFe-10% up with SFe - C group after fourth weeks, but, the difference was not significant. 4) In cellulose groups, serum-Fe remakendly decreased & TIBC increased with increase in the levels of cellulose during the fourth weeks. In agar groups, serum-Fe & TIBC tended to decrease with increased dietary fiber intake. Therefore, at high intakes of both fibers, the levels of transferrin saturation were similar to that of DFe group. 5) Contents of Fe in liver, kidney & spleen increased significantly only in 10% agar diet. The remaining 7 groups did not differ significantly. It may imply agar affect in Fe utilization from storage in rats. In conclusion, inhibitory effect of dietary fiber on Fe absorption depended upon the kinds & level of consumption Results from the present study shoves the effects of purified dietary fiber on Fe absorption in gastrointestinal tract and it may be different from those of dietary fibers consumed as a part of complex diet.
