ambas contendo 10% de proteina e isoenergeticas ouainda, com uma dieta com muito baixo teor de proteina. O ensaio biologico foi realizado em 28 dias, ao longodos quais se determinou a concentracao de nitrogenio na urina e nas fezes, alem dos calculos do Quocientede Eficiencia Alimentar (ganho de peso dividido pelo consumo de dieta), do Quociente de Eficiencia Proteica(ganho de peso dividido pelo consumo de proteina), da Razao Proteica Liquida (ganho de peso corrigidodividido pelo consumo de proteina) e da Digestibilidade Verdadeira.

Micronutrient deficiencies in normal and overweight infants in a low socio-economic population in north-east Brazil.

Background:Micronutrient deficiencies are the most prevalent form of malnutrition worldwide. Although commonly related to underweight, micronutrient deficiencies can occur in both normal and overweight children in medium- and low-income populations undergoing nutritional transition. Objective:To describe haemoglobin and micronutrient levels in infants from a low-income area in Brazil in relation to their weight-for-length Z-score. Methods:A cross-sectional survey was undertaken of 2–11-month-old infants in Laranjeiras, a small urban community in North-east-Brazil between April 2009 and February 2010. Anthropometry and assays for haemoglobin, ferritin, plasma zinc, copper and selenium and erythrocyte zinc and copper concentrations were investigated. Results:The total number of full-term infants born in the study period was 222, of whom 153 were available for the study. Three (2%) children were wasted, 98 (66%) were of normal weight, 37 (25%) were at risk of overweight and 11 (7%) were overweight or obese. Nearly all (97%) children had at least one micronutrient deficiency, 102 (67%) had anaemia, 86 (58%) and 100 (67%) had plasma and erythrocyte zinc deficiency, respectively, and 7 (5%) and 113 (76%) had plasma and erythrocyte copper deficiency, respectively. 138 (91%) children had selenium deficiency. Except for plasma zinc, the proportion of infants with micronutrient deficiencies did not differ by weight-for-length status. Conclusions:The increased risk of overweight and micronutrient deficiencies in this population highlights the need to address the double burden of excess weight with micronutrient deficiencies in medium- and low-income settings.

Development of enteral homemade diets for elderly persons receiving home care and analysis of macro and micronutrient composition

Objetivo: Desenvolver e analisar a composicao de macro e micronutrientes de dietas enterais semiartesanais para uso domiciliar. Metodo: Foi desenvolvida uma receita de dieta enteral semiartesanal padrao, com tres concentracoes caloricas, de 1500, 1800 e 2100 Kcal. Apos o preparo e teste de viscosidade, estabilidade, odor, cor e custo as dietas tiveram a composicao quimica de macro e micronutrientes analisada. O folato e vitamina D e B12 tiveram seus valores estimados por meio de tabelas de composicao quimica. Os resultados encontrados foram comparados com as recomendacoes nutricionais para idosos. Resultado: As dietas apresentaram distribuicao normal de macronutrientes. A dieta de 1500 Kcal apresentou diversas deficiencias de minerais e vitaminas. Nos demais niveis caloricos, obteve-se valores adequados para todos os minerais exceto o magnesio. As vitaminas estavam todas adequadas no nivel calorico de 2100 Kcal e no de 1800 Kcal, a vitamina E, D e B6 nao alcancaram as recomendacoes dieteticas diarias. Conclusao: A dietas padroes desenvolvidas podem contribuir para seguranca alimentar e nutricional de idosos em terapia nutricional domiciliar, desde que todas suplementadas com magnesio, e a de 1800 Kcal com vitamina E, D e B6. A formula de 1500 Kcal nao se mostrou segura nutricionalmente no que tange aos micronutrientes.Objective: the development and analysis of the macro and micronutrient composition of homemade enteral diets. Method: A standard homemade enteral diet was developed at three caloric concentrations 1500, 1800 and 2100 Kcal. After preparation and testing of viscosity, stability, odor and color, plus evaluation of cost, the chemical composition of Palavras-chave: Atenção Domiciliar. Nutrição Enteral. Análise de Alimentos.
