Brief Summary
The investigators propose to study the effects of increased iron intake by home fortification of complementary foods on the gastrointestinal microbial development, inflammatory responses, and zinc (Zn) absorption. The proposed subjects are 9 month olds living in a malaria endemic area of rural Kenya who are randomized at 6 months of age to one of three fortificant groups: 1) Sprinkles™ with 12mg Iron(Fe)/day + other micronutrients, including 5mg/d Zn (test); Sprinkles™ with 0 mg/d Fe + other micronutrients, including 5mg/d Zn (control); Sprinkles™ with no micronutrients (placebo). The investigators hypothesize that the microbiome will be significantly different in the three groups and that Zn absorption and status, in addition to immune and oxidant status will be improved in the non-Fe fortified groups when compared to the Fe-fortified group.
