Research Abstract	Iron deficiency anemia is one of the most serious forms of malnutrition. Elimination of iron deficiency on nutrition is a major issue. The aim of this study was to investigate the corresponding to iron deficiency as a whole diet, instead of exploring the iron preparation in effect for iron deficiency. In this study period, to investigate the improvement of iron bioavailability by the three major nutrients under iron deficiency, it examined whether or not the oligosaccharide was useful for iron deficiency in cases of low iron intake and pregnancy increased iron demand. It demonstrated that acidic xylooligosaccharide added diet could preserve storage of hepatic iron in adult female rats fed a low iron diet and promote of dietary iron absorption in pregnancy female rats. These results suggested that acidic xylooligosaccharide could prevent iron deficiency anemia by promotion of dietary iron absorption, and/or improvement of iron bioavailability.
