  • This study was conducted to evaluate dietary fiber intake, iron status, and their correlations in 50 female college students living in Seoul. The nutritional status was analyzed using 3-day dietary record, duplicated diet collection, and venous blood sampling. The mean values for age, height, weight, BMI, and blood pressure of the subjects were 23.2 years, 160.2cm, 53.9kg, 21.0kg/$m^2$, and 110.1/68.4mmHg, respectively. Daily intakes of enery, protein, fiber, crude fiber, iron, and heme iron were 1635.5㎉, 54.3g, 22.5g, 6.8g, 16.2mg, and 0.2mg, respectively. Fiver intake was positively correlate with energy, protein, carbohydrate, vitamin C, iron, and crude fiber intakes. Also, iron intake was positively correlated with energy, protein, lipid, carbohydrate, and vitamin C intakes. There was a significant correlation between heme iron and MFP(meat, fish, poultry) intakes. To exame the iron balance, iron intake and excretion were measured. Iron intake and excretions through urine and feces were 19.5mg, 8.5mg, and 1.6mg, respectively. Based on these iron retention and iron apparent absorbability were calculated as 9.4mg and 52.4%, respectively. There was no significant relationship between dietary fiber intake and iron status. However, there were significant positive correlation between fiber intake and urinary iron excretion.
