ABSTRACT

Introduction:

Breast milk has several compounds obtained from food sources, such as conjugated linoleic acid (CLA).

Objective:

To compare the amount of trans fatty acids (TFA), CLA and docosahexaenoic acid (DHA) in the fat of breast milk with reported food consumption. Subjects and

method:

Descriptive study of 10 lactating Chilean women. Breast milk fatty acids were analyzed by gas liquid chrornatography and results compared to data obtained from a food frequency questionnaire.

Results:

Forty-two fatty acids were quantified, TFA (3.6 percent), CLA (0.8 percent), and DHA (0.2 percent). Of the 42 fatty acids, 4 CLA isomers and 3 TFA isomers were identified. The consumption offish, milk and meat was low. A positive correlation (p<0.05) between diet and the amount of two fatty acids, linolenic acid (LNA) and DHA, was found in breast milk fat.

Conclusions:

The amount of CLA and DHA found in food consumed and breast milk had a significant correlation; however, the amount of TFA is similar to that reported in other international studies.
RESUMEN

Introducción:

La leche materna posee una serie de componentes, entre ellos el ácido docosahexaenoico (DHA) y el acido linoleico conjugado (CLA), siendo la dieta el principal aportador.

Objetivo:

Comparar el contenido de CLA, trans industriales (AGT) y DHA de leche materna con la ingesta alimentaria. Sujetos y

método:

Estudio descriptivo de 10 nodrizas, se obtuvo una muestra de leche materna, la materia grasa se analizó por cromatografía de gas-líquido, el resultado se comparó con una encuesta alimentaria.

Resultados:

Se cuantificaron 42 ácidos grasos, trans industriales (3,6 por ciento), el CLA (0,8 por ciento) y DHA (0,2 por ciento) del total de ácidos grasos de la grasa. Se cuantificaron 4 isómeros de CLA y 3 ácidos grasos trans industriales. El consumo de alimentos marinos, lácteos y carnes fue bajo. Al correlacionar la dieta y presencia de ácidos grasos, el ácido linoleico (AL) y el DHA mostraron una correlación positiva (p<0,05).

Conclusión:

Tanto la ingesta como la presencia de DHA y CLA en leche materna es baja, en cambio la presencia de trans industrial es moderada con respecto a otros estudios.
