Evaluation of Erythrocyte Iron Incorporation in Beijing Prepubertal Children Using a Single Stable Isotope Tracer Method.

Objective: To analyze the rate of erythrocyte iron incorporation and provided guidance for the iron nutrition for prepubertal children.

Methods: Fifty-seven prepubertal children of Beijing were involved in this study and each subject was orally administered 3 mg of Fe twice daily to obtain a total of 30 mg Fe after a 5-d period. The stable isotope ratios in RBCs were determined in 14th day, 28th day, 60th day, and 90th day.

Zinc Absorption from Representative Diet in a Chinese Elderly Population Using Stable Isotope Technique.

Objective: To determine the dietary zinc absorption in a Chinese elderly population and provide the basic data for the setting of zinc (Zn) recommended nutrient intakes (RNI) for Chinese elderly people.

Methods: A total of 24 elderly people were recruited for this study and were administered oral doses of 3 mg 67Zn and 1.2 mg dysprosium on the fourth day.
