    Objectives: To determine the amount of proteins and micronutrients contained in breast milk of nursing mothers treated at a Family Health Unit, in relation to those described in the literature and highlighting their importance in feeding. Methods: Quantitative, descriptive study with cross - sectional design. Nursing mothers were included in exclusive breastfeeding, from 21 days to 6 months incomplete. Obtaining infant and infant data (anthropometric data), as well as maternal milk for analysis of protein and minerals (calcium, magnesium, potassium, sodium and zinc). At the moment of collection of the breast milk sample, she was advising on the milking, hygiene and storage of the same, following the protocol recommended by Fiocruz. Results: The sample consisted of 14 nursing mothers and infants from 21 days to 6 months incomplete. In the analyzed breastmilk composition, we observed a significant difference in mean values of protein and minerals (calcium, magnesium, potassium, sodium and zinc) when compared to those described in the literature. There was no significant difference when we compared the mean values of the breast milk composition of our sample with the maternal body mass index. Conclusion: the composition of the analyzed breast milk presents a significant difference of its average values when compared to those described in the literature, considering that the geographical and cultural factors may influence the values associated with the composition of the breast milk of the samples and that are few studies on the subject.

    Objetivos: Determinar a quantidade de proteínas e micronutrientes contidos em leite materno de nutrizes atendidas em uma Unidade de Saúde da Família, relacionando com os descritos na literatura e destacando sua importância na alimentação. Métodos: Estudo quantitativo, descritivo com delineamento transversal. Foram incluídas nutrizes de lactentes em amamentação exclusiva, a partir de 21 dias até 6 meses incompletos. Obtendo dados da nutriz e do lactente (dados antropométricos), além de leite materno para análise de proteína e minerais (cálcio, magnésio, potássio, sódio e zinco). No momento da coleta da amostra do leite materno, foi orientando sobre a ordenha, higienização e armazenamento do mesmo, seguindo o protocolo preconizado pela Fiocruz. Resultados: A amostra foi composta por 14 nutrizes e lactentes de 21 dias a 6 meses incompletos. Na composição do leite materno analisado, observamos uma diferença significativa dos valores médios da proteína e dos minerais (cálcio, magnésio, potássio, sódio e zinco) quando comparados com os descritos na literatura. Não houve diferença significativa quando comparamos os valores médios da composição do leite materno da nossa amostra com o Índice de Massa Corporal materno. Conclusão: a composição do leite materno analisado, apresenta uma diferença significativa dos seus valores médios quando comparados com os descritos na literatura, devendo levar em consideração os fatores geográficos e culturais podem influenciar nos valores associados a composição do leite materno das amostras e que são poucos os estudos sobre o tema. ABSTRACT Analysis of protein and micronutrients in human milk samplesObjectives: To determine the amount of proteins and micronutrients contained in breast milk of nursing mothers treated at a Family Health Unit, in relation to those described in the literature and highlighting their importance in feeding.
