Influência da ingestão de sardinha nos níveis de ácidos graxos poliinsaturados da série ômega3 no leite materno

Abstract

Objectives: The purpose of this study was to investigate what effect the ingestion of sardines, rich in omega-3 series polyunsaturated fatty acids, has on the composition of breastmilk.Methods: This was a prospective study of 31 nursing mothers under observation at the Hospital Guilherme Álvaro. Each was given 2 kg of fresh sardines twice with a 15-day interval. Milk was sampled and a 24-hour dietary recall questionnaire was applied on days 0, 15 and 30. Milk was assayed for fatty acid content by gas chromatography. Statistical analysis of the results was performed using nonparametric tests with significance set at p < 0.05. Results:The results demonstrate that the nutritional intake of the nursing mothers was adequate at all three sample points. With regard to the omega-3 series fatty acid content of the breastmilk, it was observed that regular consumption and shorter intervals between ingestion and milk collection resulted in higher concentrations of docosapentaenoic acid and docosahexaenoic acid at 15 and 30 days into the study. Fatty acids from the omega-3 and omega-6 series exhibited a significant correlation, r 2 was 0.58 and 0.59 at 15 and 30 days, respectively. Conclusion:These results suggest that incorporating fish into the diets of nursing mother during lactation, in the form of 100 g of sardines two or three times a week, contributes to an increase in omega-3 series fatty acids.J Pediatr (Rio J). 2006;82(1):63-9: Breastmilk, human milk, polyunsaturated fatty acids, fish intake, fish consumption, docosahexaenoic acid (DHA), omega-3 fatty acids, lactation, breastfeeding.

“…O aproveitamento dos resíduos de pescado para consumo humano vem de encontro às orientações para o aumento de consumo de ácidos graxos da série ômega-3, levando-se em consideração a importância nutricional na prevenção e no combate de doenças cardiovasculares, câncer e distúrbios neurológicos (Etherton et al, 2002;Hartvigsen et al, 2003;Patin et al, 2006;USDA/HHS, 2005).…”
