A pilot duplicate diet study on manganese, selenium and chromium intakes in institutionalised children and adolescents from Guatemala

摘要: Hidden hunger occurs in the presence of an otherwise nutritionally or energetically appropriate diet that is deficient essential vitamins and minerals. Guatemala has highest rate child malnutrition Latin America prevalence hidden high. The aim this study was to determine Mn, Se Cr dietary intakes Guatemalan institutionalised children (4-14 years), a population group at high risk mineral deficiency. For purpose, contents were analysed duplicate (for 7 consecutive days) by electrothermal atomisation-atomic absorption spectrophotometry following acid digestion. from diets range 1·3-2·31 mg/d, 58·7-69·6 µg/d 6·32-27·57 µg/d, respectively. Mn values below current recommended daily intakes. A cereal- legumes-based habitually consumed population. Local vegetables, fruits nutritional supplements are included daily, but consumption fish, meat, eggs dairy products very infrequent negligible. Mean energy intake 7-d 8418·2 kJ (2012 kcal), with macronutrient distribution carbohydrates 69·4 %, proteins 12·3 % fats 18·3 %. Correlations between other nutrient also evaluated. present findings will help establish new strategies for similar groups.
