  • Lipídeos totais e alfa-tocoferol no leite maduro: Existe relação após suplementação com vitamina E

    Open AccessJuliane Oliveira De Medeiros, Juliana Oliveira de Medeiros et al.ARTICLEDEMETRA Alimentação Nutrição &…2022

    Introdução: O consumo de lipídeos durante a lactação pode alterar a concentração de vitamina E do leite materno, provavelmente, por ambos os nutrientes possuírem caráter lipossolúvel e compartilharem vias similares de distribuição, metabolismo e ação molecular. Sabe-se que o alto consumo materno de vitamina E via suplementação altera a concentração de alfa-tocoferol no leite, porém ainda não foi estudado se essa suplementação afetaria a quantidad…

  • Relationship between the dietary intake, serum, and breast milk concentrations of vitamin A and vitamin E in a cohort of women over the course of lactation

    Open AccessAna Gabriella Costa Lemos da Silva, Amanda de Sousa Rebouças et al.ARTICLEMaternal and Child Nutrition2018

    This study evaluated the nutritional status of lactating women with regard to vitamins A and E and the relationship between dietary intake and concentrations in serum and milk. A longitudinal study was conducted with 43 women at a hospital in northeastern Brazil. Blood and milk samples and food intake recalls were obtained at three moments during the breastfeeding period. Retinol and alpha-tocopherol were analysed by high-performance liquid chrom…

  • Association between maternal vitamin E status and alpha‐tocopherol levels in the newborn and colostrum

    Open AccessKarla Danielly da S Ribeiro, Mayara Santa Rosa Lima et al.ARTICLEMaternal and Child Nutrition2016

    Vitamin E is important because of its antioxidant activity in situations of oxidative stress, especially postnatally. Hence, the objective was to verify whether maternal alpha-tocopherol level is associated with the alpha-tocopherol levels of the newborn and colostrum. This is a cross-sectional study of 58 women and their term newborns from a public hospital. Blood and colostrum were collected to measure alpha-tocopherol levels by high-performanc…

  • Correlation of vitamin A nutritional status on alpha‐tocopherol in the colostrum of lactating women

    Open AccessLarissa Queiroz de Lira, Mayara Santa Rosa Lima et al.ARTICLEMaternal and Child Nutrition2011

    The adequate supply of vitamins A and E to newborns is essential. However, factors such as maternal nutritional status and nutrient interaction may limit its bioavailability. The aim of this study was to establish nutritional status for vitamins A and E and evaluate the correlation of retinol on colostrum alpha-tocopherol in lactating women. A total of 103 lactating women were recruited at a Brazilian public maternity hospital. Fasting serum and …

  • Suplementação materna com retinil palmitato no pós-parto imediato: Consumo potencial por lactentes

    Open AccessDanielle Soares Bezerra, Katherine Feitosa de Araújo et al.ARTICLERevista de Saúde Pública2009Cited by: 1References: 14

    OBJETIVO: Avaliar o efeito da suplementação materna com dose única de retinil palmitato no pós-parto para o fornecimento de vitamina A ao lactente. MÉTODOS: Ensaio clínico realizado em Natal (RN), entre março e dezembro de 2007, com 85 mulheres aleatoriamente distribuídas em dois grupos. As suplementações de retinil palmitato no pós-parto corresponderam à dose única de 200.000 (grupo experimento) UI e 0 UI (grupo controle). A quantificação do nív…

  • Impacto da suplementação com retinil palmitato no pós-parto imediato sobre os níveis de retinol do colostro

    Open AccessRoberto Dimenstein, Raquel Maria da Silva Lourenço et al.ARTICLERevista Panamericana de Salud…2007

    The increase in colostrum retinol levels following vitamin A supplementation was sufficient to guarantee double the retinol requirements of a newborn infant

  • Níveis de retinol no leite materno ao início e final da mamada

    Open AccessKarla Danielly da S Ribeiro, Roberto DimensteinARTICLERevista Panamericana de Salud…2004

    Our results suggest that hindmilk provides a higher intake of vitamin A. Therefore, it is important to guide mothers to not limit the baby's time at the breast and to avoid expressing only foremilk. In addition, it is important to standardize the time of breast milk collection in order to allow comparisons between the results of different studies on this topic
