Many Indonesian infants are already iron deficient before they reach the age of six months, which also determines the high prevalence of anemia among under-five children. Iron deficiency ultimately leads to anemia, and there is clear evidence that iron deficiency anemia during early childhood has a marked negative effect on child development and cognitive function (Lozoff et al.1991; Idjradinata & Pollitt, 1993). This negative impact on childhood development is one of the main reasons why iron deficiency during infancy should be prevented or treated.
