Since diets low in iron is usually also low in zinc, zinc deficiency --which has negative consequence on growth-- is common in iron deficiency area. In Southeast Asia, the condition is exacerbated by the rich phytate content in the complementary foods which inhibits the absorption of iron as well as zinc (Gibson, 1994). Thus, combining both iron and zinc, hence, is expected to decrease both iron and zinc deficiencies and hence improve growth and development of the children.
