On the basis of intake data and isotope studies, iron bioavailability has been estimated to be in the range of 14–18% for mixed diets and 5–12% for vegetarian diets in subjects with no iron stores, and these values have been used to generate dietary reference values for all population groups.
Iron deficiency is the most common cause of microcytic anemia. The definitive test for iron deficiency anemia (IDA) is measurement of serum ferritin.
The bioavailability of iron is approximately 14% to 18% from mixed diets that include substantial amounts of meat, seafood, and vitamin C (ascorbic acid, which enhances the bioavailability of nonheme iron) and 5% to 12% from vegetarian diets [2,4].
In an attempt to identify the most likely etiology of anemia, the laboratory component of NHANES III included measurements of total iron-binding capacity as well as whole blood folate, vitamin B 12, serum iron, ferritin, free erythrocyte protoporphyrin (sensitive to iron deficiency), C-reactive protein, plasma glucose, creatinine, and ...
