The aim of this study is to evaluate the dietary intake and prevalence of inadequate micronutrient intake in preschool children (1–4 years old) attending two-day care centers. To assess children’s dietary micronutrient intake, 24-hour duplicate diets (n = 64) were collected for one week-day, including everything the children ate and drank both at home and in kindergarten. Anthropometric measurements were carried out to evaluate the children’s nutritional status. The micronutrients copper, iron, calcium, magnesium, selenium, zinc, potassium, sodium, and manganese were determined by inductively coupled plasma mass spectrometry or graphite furnace atomic absorption spectrometry. Calcium and selenium were found with high inadequate intake rates: 50% and 42%, respectively, for children aged 1–3 years old, and 93% and 90% for children aged 4 years. Potassium was consumed in very low amounts, 13% and 5% of children aged 1–3 and 4 years old, respectively, achieved the adequate intake for the nutrient. Sodium int...
