IRON ABSORBABILITY FROM DIFFERENT DIETS IN IRON DEFICIENT ANEMIC CHILDREN BY NEUTRON ACTIVATION ANALYSIS OF A STABLE ISOTOPE (~(58)Fe) / 营养学报

ABSTRACT

The neutron activation analysis of a stable isotope (58Fe)was used successfully in the study of iron absorption from different diets in children suffering from iron deficient anemia. The method was correct and convenient, and uninjured to human body. The principle, procedure and the control of errors were also discussed. The iron absorbability of the balance diet,soy protein diet and soy protein diet plus vitamin-C were (group average?SD) 12.0? 3.6%, 10.7?4.7%, and 18,1?3.6% respectively. According to the results and the animal experiments which were reported in another paper, we agreed that soy protein unfavor or reduce the bioavailability of iron from diet, which was made by International Nutritional Anemia Consultative Group (INACG) and others, but it is still a disputing question. The data of iron absorbability from diets in children suffering from iron deficient anemia and the method of neutron activation analysis of a stable isotope (58Fe) have not be seen up to now in China. This paper will be valuable for studing, preventing and treating iron deficient anemia in our country.
