Young children in Guatemala are at risk for nutrient deficiencies due to plant-based diets and poor sanitation. Stunting, frequent diarrhea, and respiratory infections are common. Supplementation of Zn to children during diarrhea episodes has been shown to diminish duration and severity of illness. Poor Zn absorption due to high fiber and phytate in this diet might play a role in these processes. Supplementation of this micronutrient in the diet might be beneficial. The investigators will compare absorption of Zn from white maize tortillas enriched with 20% amaranth to traditional white corn tortillas in preschool children in Guatemala.
