Retinol and fat from breast milk of Brazilian mothers at high risk for food unsafe.

Abstract

Promotion and protection of breastfeeding is an important strategy in prevention of Vitamin A (Retinol) deficiency in childhood. Breast milk retinol’s allows us the chance to reach the maternal nutritional status and go over infant status. This study aimed to know the retinol and fat content in mature breast milk from Novo Cruzeiro’s population, Brazil. It was analyzes 63 samples of breast milk that belonged to 81 children. The fat content was reached by crematocrit procedure and Retinol content by HPLC. Others datas had gotten through semi-structured pre-coded questionnaires. Statistics analyses were performed nonparametric for paired samples. The median of Retinol was 0,62 μg/100mL and 1,7μg/100mL from breast milk before and after the infant had breastfed. The samples were considered statistically different (p<0,001) for Retinol contents and for fat contents (p<0,001). The results shows that Vitamin A’s content after the suck one , in each class of alimentary security, are strongly bigger than the content before suck (The Alimentary Security p=0,005; Light Unreliability p < 0,001; Moderate Unreliability p < 0,001; Deep Unreliability p< 0,001). The results suggest that the breast milk from the end of the suck provides greater retinol ingestion; breast milk before feed allows to reach The Brazilian Scale of Unreliability Alimentary. Although it is important to guide mothers to not interrupt the suck one and not to limit the manual expression only to initial breast milk.
